Digga drive key features (up to PD50)

Digga’s range of screw anchor and auger drives are the ultimate in performance, quality and cost effectiveness. With over 30 years of design and development, working in the field and listening to the needs of our customers to exceed their expectations.

All Digga drive units are manufactured in Australia, by Digga - from the hood on the drive to the gear box and Eaton motor. Our drives feature key design modifications to stand them apart from the competition:

Integrated motor and output housing unit

Our custom designed hydraulic motors were developed in conjunction with Eaton, using Eaton Geroler technology. Not satisfied with an off-the-shelf motor we developed the design specifically for the earth moving industry; significantly reducing the weight and overall length of the drive unit by integrating the hydraulic motor into the actual housing.
Merging the motor with the input housing creates a direct connection to the gearset and eliminates the need for several gearbox components. In turn, there are less moving parts and fewer potential leak points.
It also means we have been able to position the hydraulic motor ports in a more practical location; maximising manoeuvrability when drilling and offering greater protection to hoses and fittings during transport and storage.

    Less maintenance and a compact design

    Our gearboxes are made in-house at our factory in Queensland, Australia. Gears are precision machined from high grade alloy steel, specifically formulated for the manufacture of high performance gears in the earth moving industry.
    The compact design of our gear set allows for greater length under the drive, for augers or pile installation. As our drives can go down the hole they provide added depth when drilling allowing you to work more efficiently.

      Two piece shaft design with the highest side load ratings

      Digga drives have more than double the side load capacity of any other gearbox on the market. Under toque load, the Digga two piece shaft design ensures there is no increased load on the bearings. The bearings do the job they were designed for, efficiently maintaining axial and side loading.
      Making the Digga shaft a separate component to the planetary carrier, the planetary gears are isolated from the pushing, pulling and bending forces generated by the machine.
      This is highly beneficial for the operator should there be any side loading; the Digga two piece shaft design ensures there is no increased load on the bearings and the gears are protected, saving you on potential costly repairs.
      Digga drives have the highest shaft pullout rating in the industry with a heavy-duty custom designed lock-nut, and a lifetime warranty on shaft pullout.

      Diggaholics drive to keep Australian manufacturing alive.

      In recent years Australian manufacturing has being said to be in decline with retailers, producers and end users opting for cheaper, foreign imported goods. Some of Australia’s largest brands are fighting cheap international ‘copycat’ brands and competition from low-cost competitors in China, India, Vietnam and Thailand has sent many Australian manufacturers into decline. Ford, General Motors Holden and Toyota have closed their Australian plants, costing many jobs at local component and accessory makers and suppliers.

      For Digga Australia, keeping Australian manufacturing alive and continually developing jobs and trades within Australia, is key in keeping customers loyal to the brand and pivotal in future success of the business.
      Following the devastating fire at the facility and head office in Queensland almost 2 years ago, the company could have easily turned to outsourcing manufacturing overseas. Instead the owner’s dedication to Australia manufacturing and keeping jobs local saw the facility rebuilt and fitted with some of the most advanced machinery in the country.

      Today the company employs over 200 staff here in Australia and growing. Also known as the ‘Diggaholics’ the employees of Digga Australia are proud to work for an iconic Australian brand, being a part of the drive to keep manufacturing in Australia and actively strive to manufacture and distribute quality earth moving attachments and planetary drives.

      Currently supporting numerous apprentices through their work-based-learning as well as ‘up-skill’ government initiatives through a number of traineeships, Digga believes investing into their staff and creating an inspirational and innovative work environment leads to longevity and loyalty which helps the brand continue to deliver proudly made machinery attachments. Digga’s longest serving employee celebrated his 33rd year with the group earlier this year. 

      The Digga brand promises only the strongest and most durable machinery attachments the market has to offer, manufacturing 85% of all parts and components for their earthmoving attachments and planetary gearboxes in-house using some of the most technological advanced manufacturing machinery in Australia.
      Digga Australia - Australian manufacturing
      Practising lean manufacturing, Digga continue to invest into the manufacturing team and their facilities to stay at the forefront of the industry, working streamlined and efficiently to get the job done. Their 12,500sqm factory and main operating facility in Yatala, features a totally refitted machine shop and manufacturing plant of world class machinery including:

      ·      A CNC machine shop with 10 Mazak lathes and mills for precision machining and cutting of parts and components with manual machining options for greater customization
      ·      Bystronic 6kW laser cutting machine gives the facility the capacity to cut steel up to 25mmfrom flat sheets of steel up to 4m x 2m, while their HDP CNC plasma profile cutter allows Digga to cut steel up to 64mm thick with a bed size of 4m by 2.5m
      ·      Multiple press brake bending machines, saws, rollers and flight presses
      ·      4 state of the art robotic welding cells plus 30 manual fabrication bays
      ·      A custom built finishing centre ensuring a quality finish to attachments with media blasting and heavy duty powder coating
      ·      11 gear cutting machines both manual and CNC controlled giving the facility the flexibility to cut internal and external gears and splines of varying diameter and depth

      Digga CEO Suzie Wright explains
       “The fire literally breathed new life in the facility. We are continuing to reduce setup and processing times, which in turn reduce costs and allow us to stay highly competitive in both local and export markets. Our outstanding loyal team who put in day in, day out, and investment in to them is a key part of the businesses success.”

      The Digga Rotary Axe

      extreme slasher - rotary axe - digga attachment
      The Rotary Axe is the ultimate heavy duty attachment for clearing and shredding thick bush and scrub. When Southern Tool + Equipment Co customer John Hile was looking for a tool to help him clear and maintain 140 acres of land his property in Withcott stands on, we were confident the Rotary Axe was going to get the job done.

      Slashing similar products off the market, the Digga rotary axe is in a league of its own with the term ‘rotary axe’ uniquely describing the cutting action of the blades – the alternating bevels on the blades working like an axe.

      Key features of the Digga model include:
      • 20mm thick, hardened reversible steel blades for added life
      • A heavy duty fly wheel which gives smooth rotation while its weight maintains the blades momentum as they strike trees and brush to keep spinning and therefore cutting. 18 carbide grinding teeth are mounted below the fly wheel to grind tree stumps 10mm above ground level
      • Weighing just under a tone the heavy duty design of the Digga rotary axe also stops the attachment from ‘bouncing’ while grinding and hitting debris. A 6mm deck thickness ensures durability
      • Visible pressure gauge to avoid overheating and excessive stalling
      The land at John’s property is overgrown with a mixture of tree, shrub and long thick grasses with vines and rocks thrown in for good measure. John has always maintained their family property but year after year machinery attachments have failed him, not providing the strength and durability needed to tackle the different ground conditions and vegetation.
      Southern Tool - Rotary Axe - Digga Machinery Attachments
      John purchased a Digga rotary axe from Southern Tool + Co in South East Queensland after a full run down of the product and spoke with Andre Patane of their Sales Division and some of the technical team here at Digga HQ regarding the differences between the Digga Rotary Axe and other similar models on the market.

      In the few months that John has owned his Digga Rotary Axe he got in touch to let us know how he was getting on with the Digga Rotary Axe attached to his New Holland L230:

      “Whilst the rotary axe is a new piece of equipment and I’m still learning the reigns with it, I have cleared at a large amount of this difficult overgrown country. I particularly like the tapered frame at the front of the unit, as it allows you to get the axe over the top of undergrowth, tilt the front of the machine forward and drag back over the undergrowth. The heavy blades work a treat in the toughest of scrub and then the tungsten cutters under the blade will remove the stumps. It’s also protecting the top soil and leaving fresh mulch all over the cleared land, providing a great seed bed for improved pasture.
      to date, the Rotary Axe has been great and proving incredibly tough. We have never succeeded with regrowth control as efficiently to date. Our country is predominantly very rough, beautiful and mountainous with great views often spoilt by uncontrollable regrowth – until the arrival of the Rotary Axe from Digga!”

      We’ll be hearing more from John as he updates us on the progress of the regrowth clearing and fuel reduction for fire control and the robustness of the machine!

      In the meantime, click here to check out this video of some land we cleared out using the Digga Rotary Axe.

      Savic Plant Hire tell us they LOVE the Digga 4 in 1 bucket

      David Savic of Savic Plant Hire recently called in to Digga HQ and chatted to us about his Digga tilting 4 in 1 Bucket and Cleana bucket broom.

      The Digga 4 in 1 bucket and Cleana bucket broom are Australian made and feature practical features to make light work of earth moving.

      David’s business offers plant hire to all walks of constructors and earth movers and believes being versatile for his customers if very important; just like supplying them with quality products that can get the job done. That’s why he chooses Digga Australia machinery attachments.

      David has been very happy with his Digga 4 in 1 tilting bucket and Bucket Broom which he regularly uses himself around the yard and on his own property.

      The Digga Tilting 4 in 1 Bucket – sometimes referred to as a 6 in 1 bucket allows him to get full radial control of the cutting angle while maintaining all the features of the standard 4 in 1 Digga bucket.

      He commented, “From the level gage at the back of the bucket to the visibility – I can see all my cutting edges and I love it. It’s works really well”

      After recently putting his Digga Cleana bucket broom to good use around his yard, he told us he thought it was awesome.
      “I like the adjustment handles to move the broom up and down easily and it helps you level the brush on uneven ground and with the rubber guards you don’t scrape into the ground - you have to be careful, more so on bitumen but the set up here [on the Digga Cleana bucket broom] is really practical.”
      The Digga Cleana bucket broom has been designed to help clean up yards, factories, car parks or road construction sites for example. With high performance hydraulic components, a hinged lid for fast emptying, heavy duty wheels and replaceable bucket wear edges the Digga Cleana bucket broom is available in a range of width options and suitable for skid steers, mini loaders, tractors and telehandlers.
      David explained, “To tell you the truth, it was one of the industry reps that kept recommending Digga to me. I’d always used a lot of competitor products but they got damaged and I needed to upgrade. You know, the good thing about Australia is that we’re a big country with a small population and the best ideas – especially our manufacturing for agriculture and technology. The Digga products are manufactured to be easy to use and versatile, and it’s great.”

      The pink Digga screw anchor drive

      Tiah Selkrig is 'screwing' the stereotypes of gender roles in construction and proudly advertises her ‘very girly’ pink Digga screw anchor drive and matching pink excavator when on site!

      Digga screw anchor drive - pink Wanting to show construction sites all over the Hunter Valley region that girls can do just as much as boys, Tiah decided she was going to raise the awareness of being a women in construction and painted her Digga drive pink to match the back of her excavator.

      Tiah works for AAA Down Under offering earth moving, civil construction and foundation services to the Hunter Valley region. AAA Down Under is her Dad’s business and she explained growing up around her father using earth moving machinery inspired her to become an operator just like him. Today she operates her excavator with the Digga MD190 screw anchor drive to install screw piles and said,
      “I love the Digga drive, it’s the best thing I’ve got!”
      Tiah decided to custom paint her Digga MD190 screw anchor drive ‘Breast Cancer Pink’ and she explained “I have a close family friend who got through a battle with breast cancer. The idea of the pink drive was originally for her, but then it also shows it’s mine and that I’m a girl working on the site!”

      Tiah has very strong feelings towards being a woman in construction and feels more women need to get involved. According to a report by the University of NSW women represent only 12% of the workforce in the Australian construction industry in 2016.
      “Unless I went through my Dad’s company I don’t think many other businesses would have given me a go as an operator, because I’m female. My pink drive is a symbol that I’m a girl and that girls can do just as much as boys can. More women need to get in this kind of work because a lot of men under estimate what we can all do, it’s good fun to prove them wrong and I hope everybody loves my very girly pink drive just as much as I do!”

      Drilling expert uses Digga 2-speed auger drives.

      Adrian Eagan, aka Baldy has been drilling in one form or another all his working life. Working for one of Queensland largest earthmovers L&D Earthmoving, we wanted to hear what he makes of the Digga drives he puts to work every day.  

      L&D Earthmoving were established in 1954 and Baldy has been with them for the last 25 years explaining that the company service a mix of commercial and domestic customers “from backyard bobs to major infrastructures – there is virtually no where we can’t service!”

      Covering all of South East Queensland working in light dusty sands and clay to solid blue metal Baldy really puts his drives through their paces.
      “I run a few 4.5 or 6 tonne combos for all our everyday work and light duty drilling with the Digga PD3. Then I operate an 18 tonne excavator with a 2 speed Digga PD30.”
      The Digga PD30 is an upgrade from the PD18 Baldy used to operate but he admits “after 8 years of heavy work, I finally managed to break the PD18…” 

      Of course a regular service and maintenance check-up would have shown what was behind Baldy’s PD18 going bust on him and after learning his lesson with alternative brands says
      “My new Digga 2-speed PD30 is awesome. It has all the power and speed I ever need. Some of the holes I drill can be 4 – 5m deep and 600mm diameter into solid blue metal and it’s handling it all with ease.”
      The range of 2 speed Digga auger drives give you the flexibility to work a wider range of applications with a high speed, low torque setting for the smaller auger jobs when you need that extra RPM and a low speed, high torque for when you really need to grind out that larger diameter hole.

      You can find out more information on our range of auger drives and 2 speed options on our website:

      Benefits of the Digga cradle hitch

      The Digga excavator cradle hitch was designed and manufactured to improve operator and workers safety when manoeuvring around sites whilst also providing a simpler connection to augers and piles.

      The double pin hitch with drive unit cradle allows the operator to angle the drive up to 90 degrees with greater support given by the cradle so it is easier and more stable when connecting to augers or anchors.

      The cradle also acts as a support mechanism when manoeuvring around the work site allowing the drive unit to rest on the cradle, stopping it from swinging around over uneven terrain.

      Designed and manufactured to suit the size of the different drive units available, the hitch can be ordered with loose or fixed pin options and suitable for use with PD3 – PD50 Digga drive models.

      When drilling you should lift the cradle up and away from the drive unit. Do not drill with the cradle resting against the drive unit. This will damage the cradle hitch and your auger drive. See the comparison diagrams below:

      Digga trencher: Bigfoot vs Hydrive

      Diggas range of trenchers are ideal for digging trenches for pipes, road repairs and general construction.

      The range includes the mini trencher, Bigfoot trenchers and Hydrive trenchers and every model ins manufactured in-house to the highest industry quality at our facility in Queensland, Australia. They feature an Eaton motor and Digga made gearbox enquiring reliability and performance, but how do you know which trencher is suitable for you?

      Here we go over the key differences between the Bigfoot and the Hydrive and machine suitability.                                                                       


      Bigfoot Trencher
      • Ideal for inexperienced or experienced operators.
      • The Bigfoot trencher has a skid foot which makes getting the correct consistent depth easier. The foot has 3 or 4 pre-set depth settings dependent on the model.
      • The Bigfoot has 1 spoil auger. All spoil is extracted to one side of the trench leaving one side clear to work. 
      • 100mm to 200mm chain cut width with 1.654" pitch 
      • 150mm to 300mm chain cut width with 2" pitch 
      • Available for mini loaders, skid steers, telehandlers, tractors, backhoes and excavators up to 8 tonne. Not suitable for 3pt linkage.

      Hydrive Trencher
      • Ideal for experienced operators and operators who trench for a living. 
      • The Hydrive trencher has no skid foot, instead it has a spoil auger on each side. This helps clear the trench of spoil more efficiently, leaving the trencher to do more cutting and less clearing.
      • The Hydrive features a 3 point drive system with the motor sitting in the highest sprocket well out of the dirt.
      • Due to the 3 point drive system the chain is never in contact with the boom reducing drag and resulting in increased efficiency. 
      • 100mm to 300mm chain cut width with 1.654" pitch 
      • 150mm to 350mm chain cut width with 2" pitch 
      • Recommended for use on skid steer loaders, track loaders, tractors, backhoes and excavators up to 8 tonne.

      The Digga 4 in 1 Bucket is more than just a bucket.

      digga product - 4 in 1 buckets
      A Digga 4 in 1 bucket is arguably one of the most versatile earth moving attachments available for both construction and agricultural users alike.

      As the name suggests, a 4 in 1 bucket enables you to perform 4 different functions which Digga reference as standard bucket operation, grappling, levelling and dozing.

      A 4 in 1 bucket adds great value to the operators business and machinery over a standard bucket:
      • Standard bucket operation
        When the bucket is fully closed the Digga 4 in 1 bucket can be used as a general purpose bucket for moving dirt and material etc.
        Digga tip: If you are dumping into a truck you can dump at a greater height than a standard bucket by opening the floor to release the material. 
      • Grapple operation 
        With the bucket above an object, open the floor sufficiently and lower the bucket down so that the object is between the jaws. When you close the floor, the object will become clamped between jaws so you can lift and move.
        Digga tip: Always use the side jaws to pick up objects. Do not use the floor to pick up or pull objects as this will cause damage to the floor/ bucket and you may lose your warranty.
      • Levelling
        In the operator’s manual this is referred to as ‘back dragging’. The user drags and levels dirt or material with the floor fully open and the back edge of the bucket on the ground to level out.

      • Dozing
        With the floor of the bucket open, tilt the bulldozer weldment forward so that the front cutting edge penetrates the desired depth into the soil or materials to push and move the ground.

      Key features of the Digga 4 in 1 bucket

      Digga’s extensive range of 4 in 1 buckets are suitable for mini loaders, skid steers and tractors. The durable, strong and 100% Australian made Digga 4 in 1 bucket features a ‘wear plate standard’ hardened steel floor and comes complete with a thick, heavy duty, fully welded grill to provide clear vision of bucket edges. With cutting widths from 880mm to 2200mm, the Digga 4 in 1 bucket is available for mini loaders, skid steers and tractors.

      Optional bolt on cutting blades for Digga 4 in 1 bucket

      All models in the range are available with optional reversible bolt on cutting blades. The blades are sectioned into 3 and available for fixture on to all 3 edges of the bucket. As the cutting edges of your bucket will naturally wear faster, why replace the whole blade when you can just replace the worn sections?

      With the optional Digga reversible cutting blades for your 4 in 1, you can replace wear parts section by section saving you time and money.

      See the diagram below which highlights the three different edges and how the blades are sectioned into 3 so you can replace and rotate the blades depending on your usage.

      Helical piling experts give Digga's Australian Manufacturing a tick in the box

      digga machinery attachments
      Coming from a background of Australian small business, helical piling experts Brodie and Rob Houghton believe that supporting Australian manufacturing, skills and ingenuity should be top of the list when selecting new machinery attachments.

      Brodie and Rob Houghton have over 25 years of experience in small business development, servicing specialist engineering and construction industry niches, including extensive experience in the Residential, Civil and Commercial Construction disciplines. Brodie and Rob are now the Directors of Solidity Pty Ltd, specialists in Helical Pile manufacture and installation.

      Solidity service the entire state of Victoria, with emphasis on areas with swampy or sandy foundations, where helical piling provides significant economic and structural benefits over the concrete bored pile equivalent.

      The Solidity team operate using a number of different machinery platforms, and have recently purchased a new 5.5T excavator. Each of their excavators is matched to a high torque auger drive unit and a digital torque monitoring device which Brodie says “ensures a reliable and efficient pile installation.”

      With Solidity’s core values centring on quality and service, Brodie isn’t prepared to lose focus on delivering reliable and efficient pile installation for his customers when selecting his new machinery attachments. Despite his years of experience with different brands and models of machinery attachments, he still conducts a significant amount of shopping around before choosing the right brand of attachment for him.
      “From living through a huge dynamic shift brought about by the downturn in our economy and rise in foreign imports we see the need to constantly strive to support Australian manufacturers wherever possible. We chose Digga due to their reputation for reliability and their Australian heritage. In the development of Solidity, we see an opportunity to build a business with a core ethos supporting Australian skills and ingenuity and as such, one of the first boxes on our list of criteria when it comes to selecting machinery attachments was the country of origin. Digga ticks that box for us!”
      As expected, Solidity undertook further research into Digga and other machinery attachment manufacturers, receiving first word reports from their trusted associates, consulting the internet and seeking advice from third party sales and technical staff. Brodie explained that in the end, “It was countless anecdotes from associates in the industry which helped to confirm claims of reliability made by sales staff from various machinery resellers that cemented the decision to use Digga attachments exclusively as our business grows.”

      Solidity Pty Ltd paired their new 5.5T Hitatchi ZX-55U to a Digga PD12 Auger drive, with RC8 Rock Drill and a Digga Pressure Differential Gauge and told us that they have been extremely pleased with the all their new Digga gear so far.
      Digga machinery attachments
      Thanks to the unique Digga/Eaton bell motors used in the Digga drive range, the PD12 produces significant torque outputs which Brodie believes to be suitable for almost all residential screw piling applications and adds that “the real benefit for selecting the PD12 for us is having the confidence to put the drive to work every day without the worry of failure or malfunction”.

      The Solidity team have already been using their drive daily along with the Digga Pressure Differential Gauge. Designed to give you greater accuracy in your work, Brodie explained that the gauge has really helped him and his team to reliably and accurately compile loading correlation charts based on the dynamic load testing of their products, cross referenced to installation torque calculations.
      “By using the Digga Pressure Differential gauge, we take away any and all guess work from our process – ensuring our installations are performed correctly every time.”
      By helping to ensure a higher degree of quality control throughout their projects, the Pressure Differential Gauge has allowed Solidity to reduce risk factors in their operations, which in turn have generated savings that they have passed onto their clients.

      Every product in the Digga range of machinery attachments has been designed and built for the varying Australian conditions, providing customers with our uncompromised dedication to high quality, competitively priced, Australian manufacturing, something which Solidity put their trust in, “given that the Digga products we purchase are all Australian Made, we take solace in the notion that if any issues were to arise with any of our purchases, parts and expertise are only a phone call away, giving me even more peace of mind!”

      Digga 4 in 1 bucket is bucket loads better than the rest!

      The Digga 4 in 1 bucket is a practical solution to tackle many applications in construction and agricultural job sites.

      Ace Rental is an equipment rental company based in South East Queensland. They supply a range of backhoes, graders, excavators and skid steer loaders with earth moving attachments to the Gold Coast, Brisbane and all across the south east Queensland region to a mix of customers from different industry sectors.

      Company founder and Managing Director Mick Sheldon has been in the earth moving industry for over 31 years and opened Ace rentals in March 2003. Mick has built up his business reputation by supplying quality earth moving machinery equipment to a demanding work sector.

      To continue to meet his customer needs, the business regularly upgrade and replace their machinery with new models and when Ace Rentals purchase any new machine, they often come direct from the dealer with buckets and other attachments already fitted.

      Over the 15 years that Ace Rentals have been in operation Mick has found that these attachments and specifically buckets, are “by no means serviceable for the life of the machine” and in most cases a more robust bucket needs to be fitted.
      Testimonial - 4 in 1 - Digga bucket
      He said, “That is why we use Digga buckets and attachments. They’re engineered for the Australian job site - from the steel used to manufacture the buckets to the overall quality of the manufacturing, it is much better quality than that of other equipment out there.”
      “All in all we are extremely happy with our decision to choose Digga buckets, and the feedback from our clients has been overwhelmingly positive. As we are a service based business and we value our client’s feedback, we will continue to align ourselves with Digga and their quality machinery attachments for years to come.”

      The Digga ECV and pile kick back when installing screw piles.

      Digga Australia - digga drive unit
      Screw piles or helical piles are installed to an engineered torque specification. By the time installation torque is reached and the operator stops the machine, the screw pile has built up rotational energy - similar to a rubber band on a wind up model aeroplane.

      This can cause the pile to momentarily 'kick back' and force the energy back up the screw pile through the drive shaft, the gear box and the hydraulic motor. This action effectively turns the motor into a high speed pump, generating cavitation of the motor which causes motor failure and potentially expensive replacement costs.

      See the diagram below, the red arrow demonstrates the force of the energy up the screw pile.

      Digga's flow reversal bypass valve (ECV) is fitted as standard to Digga Screw Anchor Drives and can be retro fitted to drilling drives as required.

      The Digga ECV effectively protects the motor in your drive from rapid oil decompression and easily converts your auger drive into a dedicated screw anchor drive.

      Digga tips - servicing and changing the oil of your Digga drive unit.

      It is important to service your Digga drive unit and change the oil regularly as per the owners manual. This will ensure longevity and performance of your drive.

      • The oil in your drive unit is independent to your hydraulic system.
      • Oil from your machine does not lubricate your drive unit.
      • As a result your auger drive requires regular oil changes to remain in perfect working condition.

      The images below illustrate the importance of regular servicing of your auger drive in accordance with the owners manual.

      The 3 drive units were tested in our Hydraulic Cyclic Testing Unit where 10 years of wear and tear was simulated. Oil was changed in the drives at different intervals illustrating the wear caused by neglect. Changing the oil and a regular service of your Digga drive unit is crucial to its longevity and performance.

      Digga tips - the importance of vertical alignment when drilling.

      Digga machinery attachments
      Natural arc movement of the boom causes the dipper arm to move out of alignment as it is raised or lowered. Constant operator adjustments are required to maintain vertical alignment. Failure to do so will create significant side load on the auger drive and auger.

      Digga auger drives are pendulum drills designed to hang freely from the excavator mount. Excessive side load may result in bent auger flights, pipe and hubs as well as potential damage to the auger drive shaft, seals and gearbox.

      Excessive side load may also cause socket and pilot breakage especially when drilling into hard ground.

      You can find more info and tips for drilling in harder grounds such as rock or frost here.

      Foundation Technologies make a commitment to Digga auger drives and their machinery attachments.

      Digga Machinery Attachment
      Steve Hassett, Foundation Technologies Australia business owner and co-founder used his first Digga auger drive unit in January 2017 and since then he’s never looked back; making a commitment to Digga and their Australian manufacturing.

      Starting off with just one machine in 2012, Foundation Technologies now have six machines ranging from 1.7 – 13 tonne excavators, specialising in residential screw piling.

      For the last five years Steve has been using alternative machinery attachment brands but following his success with his first Digga purchase earlier this year he has decided to change all of his auger drives over to Digga Machinery Attachments.

      Steve has been extremely impressed with the technology the Digga auger drives offer, particularly the 2 speed units (which he now owns 2 of) and he says it’s something that the rest of the market doesn’t offer, “our Digga PD12 on the 3.5T Yanmar gives us up to 9000nm of output torque with the opportunity to help out our clients where access is tight.”

      Our 2 speed drilling auger drives give a high speed, low torque setting which is ideal for smaller auger jobs when you need the extra RPM, and a low speed, high torque for when you really need to install to a higher toque. Having a greater performance with these 2 speed options gives you more practicality on jobs; it’s like having 2 drive units in 1. You can find more information on the Digga 2 speed auger drives on our website.

      Purchasing an Australian brand plays a big part for Steve in his buying decisions especially when he knows his products are manufactured right here in Queensland,
      “With the service offer and the back up support Digga have given me it’s all very impressive. The team down here in Melbourne especially have been great, and I’ve pledged my commitment to Digga Australia to help grow my business!”
      Foundation Technologies are one of the largest contractors of screw piles in Victoria and geared up to supply and install screw piles for the residential building market. Steve Hassett has an expert, direct knowledge of the screw piling industry and dedicated to providing cost effective and fully engineered solutions for his clients that will stand the test of time.
      In addition to leading the market in the installation of steel screw piles, Foundation Technologies Australia sponsors a team of young developing cyclists and has been a major sponsor of the Master Builders Association of Victoria for many years. Steve feels a sense of community and giving back to the industry is equally important as having a successful business.

      The evolution of screw piling.

      It is said that the first recorded use of a screw pile was by Alexander Mitchell, a brick maker and engineer from Ireland who coined the term ‘screw-pile’ in 1833.

      Initially the concept of screw piling was used to provide solid foundations for lighthouses in soft soil and provided enough holding power to safely moor ships in the harbour.

      The original screw pile concept cannot be officially confirmed but in the April 1848 issue of the Civil Engineer and Architects Journal the article highlights the mechanics of the bearing power of screw moorings and screw piles which Alexander Mitchell is argued to have introduced: 
      "The origin of the screw-pile was the screw mooring, which was designed for the purpose of obtaining, for an especial purpose, a greater holding power than was possessed by either the ordinary pile or any of the usual mooring -anchor blocks, of however large dimensions.... whether this broad spiral flange, [or ’ground screw,’ as it may be termed] were fixed upon a spindle, and forcibly propelled by rotary motion to a certain depth into the ground, an enormous force would be required to extract it by direct tension"
      It wasn’t long after this that screw piles were being installed all around the coast of England and Ireland and soon after that the method was being exported to the United States of America.

      During Mitchell’s era, the design and application of screw piles was by trial and error and it wasn’t until later down the line that the strategic use of screw piles begins to take place.

      Screw piles were used to support tension loads, compression loads, overturning moments and combined loading – as we see in many modern foundations today.
      Over the last 60 years while screw piles have often been associated with the electric utility industry as helical anchors for guy wires for poles and towers, they have found their way into nearly every aspect of civil construction: building foundation support for new construction, pedestrian bridges and walkways in environmentally sensitive wetlands and other areas, slope stability repair, tiebacks in temporary earth support, underpinning foundations for temporary structures, foundations for light and signage structures and wind generators, tension anchors for transmission towers and cell towers, underpinning of existing structures, foundations of bridge foundations, and a variety of other geotechnical applications.

      A key feature of screw piles is the ability to monitor the installation of every pile by careful monitoring of the installation torque and rotation as the pile advances. Even though the required installation torque relates to the specific geometry of the pile, including the helical sections and the central shaft, the torque also relates to the interaction between the screw pile and the soil. Therefore, the resulting installation torque record provides a means of direct quality control and assurance that can be used to verify soil conditions at each pile location, as well as to provide an estimate of pile capacity through correlations between torque and capacity. This is particularly important since it is usually not possible to have a soil boring at each pile location. The installation torque provides a specific log of the conditions at each location and allows for adjustments to be made to ensure that the desired pile capacity will be reached. This also means that each pile is tested and in most cases can be used to immediately support design loads.
      Australian screw piling expert and business owner Brodie Houghton of Solidity from Victoria, told Digga that they see helical piling as the next big shift in building technology, with a much needed flow on effect to both profitability of the building industry and housing affordability in general. Houghton explained: 
      "Builders who are conscientious of project economics are already making the shift to helical piling in hordes. Screw piling [with Solidity*] not only eliminates costly delays to the building program by offering all weather installation ability, but further simplifies the building process by eradicating the need for additional base stage inspections and doing away with dewatering as a concern. Adding to this the reduced material cost of helical pile supply over concrete, helical piling can produce savings of up to 20%* over an equivalent bored pier foundation system."
      There are a number of advantages to screw/ helical piling which we discuss in more detail here, (Advantages of screw piling) but Houghton goes on to tell us:
      "When you consider the environmental impact of a project credence is often not given to a well designed and executed foundation system which significantly reduces the wider environmental impact of a project, along with the immediate effects on local ecology. The simple disturbances to the environment brought about by the excavation of 0.5-1CUM of spoil, which is then relocated to either a tipping site, or another area on the subject building site can have massive effects on local flora and fauna. Being that helical piles are a type of displacement pile, there is little to no spoil disturbed during installation." 
      Today, almost any conventional piece of standard excavation equipment, such as a track or wheeled excavator, a mini excavator, a backhoe or a skid steer may be easily fitted with a low-speed, high-torque hydraulic head to provide the required torque for installation. Even in areas of limited access or low head room such as inside the basement of a structure, a small hand-held portable hydraulic torque head and a torque reaction bar can be used to install screw piles inside buildings, providing up to 5,000 nM of torque.

      Digga see the installation of screw piles as a versatile alternative to traditional methods of foundations and as more applications are being found for the use of screw piles they are fast becoming an attractive alternative to traditional cast in place concrete foundations.

      Digga tips - best practice when drilling in rock.

      When drilling rock or frost, we recommend that you periodically remove the auger from the hole. That is stop drilling, bring the auger head to the surface to allow air into the hole.

      While it may seem excessive to have to bring the auger out every few minutes, you will find you will actually drill the hole quicker and be more efficient with your wearparts.

      By lifting the auger out of the hole, it allows the air back down the hole. When you are drilling for an extended period of time, the air is expelled from the drill face and it creates an oven effect at the bottom of the hole from the heat of the drill against the rock; the face of the rock you are attempting to drill will glaze over, (like it has been polished) and become a harder surface.

      By lifting the auger out of the hole it allows air back down, cools the teeth tips and also allows you to check the teeth and replace if necessary – they are after all wearparts….

      We commonly hear of people adding water to the hole, but this alone is not the answer. The frequency of removing the auger from the drill face has a much greater benefit. When drilling rock a small amount of water will certainly help to bind up the spoil, clear the head easier and help cool the teeth down but as we all know, water is not always readily available, especially on remote worksites.

      Summit Landscapes of NSW tell us why they choose Digga Machinery Attachments.

      Offering practical solutions for our customers is imperative for Digga and our range of machinery attachments.

      Proving just that is Mitch Wetton from Summit Landscapes. The local family owned and operated business working in the Smeaton Grange and Narellan areas of NSW specialise in construction landscaping, concreting and all excavation/ bulk earthworks.

      In the last 15 years Mitch has grown to love Digga Machinery Attachments.

      He had been using a range of Digga attachments through rental companies for several years but felt it was important to invest in his own attachments following successes servicing both small and large builders on a residential and commercial scale.

      Mitch purchased his first Digga attachment almost 10 years ago and hasn’t looked back since, with his range of Digga attachments growing annually!

      He regularly uses his Digga Auger Drive units with rock combo and dedicated rock augers to drill holes for structural piers in concrete and post holes for retaining walls.

      He boasts multiple high volume buckets for his Bobcats which are used on a daily basis for earthmoving and digging and he says his Digga Pallet Forks are extremely useful when unloading his trucks and moving materials around his yard.

      The Digga Ezi Loader ramps have become an essential part of loading up as well as doubling as a float.
      “It’s the peace of mind in knowing that the guys at Digga are local and helpful and totally dedicated to their products and service. I’ve been using Digga machinery attachments for approximately 15 years now and they continue to offer great competitive pricing and practical tools to help get the job done!”

      ‘Unbreakable’ screw anchor drives the foundation of successful screw pier contractor.

      Using the Digga screw anchor drives for screw piling - customer review
      A man who spent years trying to break Digga screw anchor drive units now says he can’t run his business without them.

      Geoff Taunton runs Gold Coast Screw Piers, a Queensland-based deep foundation system provider servicing more than 200 clients from Coffs Harbour to Cairns. Explaining the history of his business, Geoff told us:
      "Back when Digga was still in the R&D phase they would give me a new test auger drive unit and tell me to go and break it. Installing screw piers and bored piers involves putting extreme vertical force on the piece of machinery attachment. It’s extremely harsh on the equipment, so it was really an ideal testing ground for the drive units. I would break the drive and tell Digga exactly what I was doing and what pressure it was under when it broke. They would use that information to improve the design, then give me a new one to break and the process would start again. These days it’s pretty hard to break a Digga screw anchor drive. For such a severe application, the success rate we see with our Digga drive units is nothing short of astonishing.”
      A Digga drive unit powers the digging/boring attachment on a piece of earthmoving equipment. The power and efficiency of the attachment is directly related to the quality of the screw anchor drive unit.
      The new generation Digga screw anchor drives are the culmination of 30 years of Australian design and development. They are optimised for the tonnage of the machine, making it simple to select the correct drive.

      Screw piers or screw piling is an alternative to bored piers and traditional stumps where a hole is dug and filled with concrete. A screw pier is a heavy duty steel tube with a screw head at one end that allows it to be literally screwed into the ground. This approach minimises waste and mess, and it saves significant time on installation. Screw piers can also be adjusted once they’re in place, making them more flexible and suitable for almost any building style.

      “We do screw piers for everything from swimming pools to 13-storey buildings,” Geoff said. “The idea is to transfer the load from the structure’s immediate footings down to an appropriate depth to create more stability and less movement. It’s ideal for earthquake zones and we’re looking to expand into areas like New Zealand in the next year or so". As well as being faster and more flexible, Geoff explains that the screw pier system is also cheaper than concrete piles:
      “I’m lucky in that we have excellent market share, but it’s still incredibly important that we be up and running all the time. I can’t afford an equipment failure and the Digga screw anchor drives are absolutely essential to what we do. We can’t function without them. With all of the R&D they did and still do, I believe the Digga auger drives are basically unbreakable. When you match the right drive to the right machine for the task, no one can compete with the speed, efficiency and productivity these drives provide.” 
      Geoff says a regular maintenance schedule is all that’s needed to keep the Digga auger drives up and running, year after year:
      “I’m still running the first drive I bought from Digga 10 years ago. A daily 10-minute maintenance regime plus a service from Digga at regular intervals is all you need to keep them working reliably. If I break an auger drive now it can always be repaired and put back to work as good as new. There’s no need to go out and replace your auger drives in the same way you would replace your excavators.”
      Geoff now runs 18 Digga drives ranging from the smaller PD5 units to the UD300 for larger jobs. The augers are matched to a fleet of excavators that range in size from 3.5 tonnes to 35 tonnes. 
      Geoff says the unrivalled quality of the Digga drives is matched by its service.
      “The service I get from Digga is perfect. I’ve tried others and they simply don’t measure up. They’re very fair, incredibly responsive and, most important, they stand behind their product so I know if I ever have a problem it will be resolved – and fast.”
      Digga drives are designed and manufactured specifically for the harsh Australian conditions, where extreme heat, dust and hard soils are particularly tough on equipment. Digga manufactures its gearboxes in house to ensure world leading manufacturing processes, tolerances and quality controls through cycling testing and FEA analysis. As a result, Digga can offer the industry’s longest warranty on gearboxes at five years, plus a three-year warranty on motors.

      Digga’s proprietary hydraulic motor and planetary gearbox means the drive units are compact and lightweight, require no case drain, complex hosing, valving or filtration and no detuning of the machine. An inbuilt pressure relief valve is standard on drive units for machines above 12 tonnes.
