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 energy that is stored in the anchor needs to be released before the drive unit is disconnected. The ECV bypasses the stored energy allowing the anchor to “unwind” in a controlled manner. Without this valve, the pressure contained when holding the pile in place would be forced up the pile and into the drive unit resulting in potential damage & costly repairs for the motor and gearbox.

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


Digga's flow reversal bypass valve (Energy Control 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.

To retro fit the ECV to your auger drive follow the 3 steps below:

Over 30 years of Digga attachments - Ron’s Landscaping

Machinery and earthworks-enthusiast Ron Bates from Ron’s Landscaping tells us he’s been involved in the industry over 30 years. Being a very brand-loyal Aussie bloke, Ron swears by two brands he has stuck with over the years - Bobcat for Skid Steer Loaders and Digga for machinery attachments.
“The reason I chose Digga was because I couldn’t justify the price of the other attachments on the market compared to the quality. And seen my Digga attachments are still running today, it was well worth it! I started off with a PD3 and an auger to fit my machine 30 years ago. Not long after purchasing another few augers, I bought a trencher and a slasher – which are now over 20 years old too.”
Being involved in the industry for so long, he sure has some great experience and likes to get the most out of his attachments. “I do all types of machine-work now, from digging dams to clearing, rural fencing, trenching for farmers, plumbers, electricians – basically anyone who needs some help digging and clearing around Hunter Valley in New South Wales. My augers are used to dig holes for fencing, tree planting, putting up sheds, footings for concreters etc. With my trencher I’ve event cut out large trees or worked on garden beds – I just love the variety of applications. You’ve got to think outside the box & you’ll be able to do anything with them.”, Ron tells us.

“Of course, I’ve had auger teeth, pilots, some hoses and trencher wear parts replaced over the years, but other than that they’ve been very efficient. Digga makes something that lasts - my gear works hard every day; they get a good run. I would recommend the attachments to anyone!”

Ron also LOVES his Slasher. The Digga Slasher attachment is suited for skid steers, mini loaders, tractors or excavators, used to effectively cut and clear grass and low ground shrubbery - ideal for landscaping, agriculture, roadway maintenance, parks maintenance, and general slashing.  
“I especially love my Digga Slasher because it just works so well, and it never lets me down. – I use it mainly around farms to clean up paddocks and manage all scrubby & rough bush up to 8ft tall.”

Check out this video by Ron, slashing some bush around a farm in Hunter Valley.

How to Service Your 4in1 Bucket - Digga Service Tips

Even though a key feature of the 4in1 bucket is low maintenance, there are a couple of checks you can do before each use to make sure you work efficiently and safely.

We recommend you carry out the following steps on a regular basis to ensure the best performance of your 4in1 bucket:
  1. Check if all your safety stickers are in place, understood and followed correctly. If you are unsure about the signage, all the correct information is provided in your operator’s manual of the 4in1 bucket.
  2. Make sure that all nuts and bolts are tightened on your linkages and pins.
  3. Check the bucket’s hydraulic fittings and hoses for any leaks and make sure that no leaks are present.
  4. Check for any wear and tear on your pins, linkages and cutting edges of your 4 in 1 bucket. If you find excessive play in your pins and linkages or you have a worn-down cutting edge you can refer to your operator’s manual or get in contact with us to replace or repair any damage or excessively worn parts. Simply call our service department 1300 784 223
  5. Always remember: any excessive build-up of debris around your cylinder can damage the cylinder rod and dust seal. So, make sure to keep your cylinders clean and free from debris. Any damage by build-up may void your customer warranty.
  6. Grease your bucket every 10 hours of use - generously but not excessively. Grease nipples are located at the top and bottom of the cylinder and on the front of the pivot linkage. After greasing, be sure to wipe away any excess grease, as it may attract dirt and debris, which can add to the wear and tear on your pins and linkages.

If you’re unsure of any of this information, make sure to check the operator’s manual or just give us a call at 1300 784 223 – we are happy to help.

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.                                                                       

KEY DIFFERENCES

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.

Digga tips - attachments for drilling in different ground conditions.

When drilling in different ground conditions you need the right speed and the right cutting system on the auger to suit the different ground conditions. For efficient drilling on any machine requires power (torque) and down pressure.

Digga augers perform better at an optimal RPM against the ground conditions they are against. Similarly the auger diameter will perform better at certain speeds.
For example: the larger the hole and harder the ground conditions, the slower you will need to drill. The smaller the hole and softer the ground conditions, then more speed is required.

Digga recommends the following for attachments for the different ground conditions:
  • When ‘general purpose’ earth drilling you can drill faster. The Digga A range of augers will be ideal here. These augers are also better for clay as the bladed teeth ‘shaves’ the spoil a layer at a time. Like scraping butter with a knife.
  • In heavy earth, clay*, soft chalky rocks you want an auger with tapered teeth. The Digga RC range of augers is the ultimate all performance auger and will cut cleanly into earth and chalky rocks. The teeth are tapered to be able to rip the fracturable rocky/earthy ground. *Please note, this range is not ideal for drilling in clay with smaller machines 4 tonne and under.
  • When drilling into rock you are going to be most effective at a slower speed with a greater amount of power. Too much speed creates too much heat and will actually ‘polish’ the rock smooth rather than chipping away at it. Too much speed will also cause the teeth to skip across the top of the rock and it will not be able to pick and rip into the rock to break it out.
You can find more information about drilling in rock here.

10K worth of Digga attachments won at DDT!


“What a day we had at DDT” – Fiona from Albury, Wodonga told us the funny story about the day she won the 10K Digga Voucher at the Diesel Dirt and Turf Expo. “My partner Dan, who owns an earthmoving and tree-logging business spontaneously decided to head up towards Sydney to take a look at a second-hand truck, so I said, why don’t we make a few-days trip out of it? That’s how we ended up at the DDT, since Dan then also wanted to check out some equipment for his business. As soon as we entered the show a guy approached us with two hats, which we should wear for a chance to win a $50 petrol voucher. I told Dan, let’s do it – we put on the hats and started walking around – it was a horrible rainy day – but there was plenty of stuff to look at. Somebody then told us about the large Machines4U & Digga prize draw. Seeing as I wanted to keep myself busy throughout the day, while Dan was looking at all the machinery, I decided to go ahead with it and collect all necessary stamps on our ticket at each station. Because we had done so well collecting them, we made a point in finding the last one at the end of the day.

I told Dan what a waste of time it was wearing the hats – and few moments later someone walked up to us with the $50 petrol voucher. How lucky, we thought! And even more incredible was the phone call I received on the following Monday - Digga telling me that I won the 10K Digga attachment voucher as well! I just couldn’t believe it.

I own several businesses; however, they are car washes and laundromats. I thought what on earth am I going to do with this voucher? Lucky my partner has an earthmoving business and owns a Bobcat, so he made the most of it! He went ahead and ordered a rock bucket with grapple, a stick rake and ramps. It worked out really well for him seeing as he is involved in tree logging and selling firewood, the equipment got put into practice straight away.”

Dan told us that he was pretty stoked to hear about Fiona’s win. He has been buying Digga attachments for years “I own a few Digga attachments including auger drives, augers and a hydraulic log grab – I’ve always been happy with the brand and quality. I use the new stick rake for farm clean-ups to environmentally harvest fallen timber for my firewood business. The Rock bucket comes in handy everywhere – to load the hopper with woods, cleaning yards – it just speeds up wood processing and leaves less rubbish. I also use the rock bucket for my earthmoving business. On a recent project (see photo) we’ve been jackhammering out rock, which we were then able separate from finer material and use it for a large retaining wall. The new loading ramps come in handy to replace my old ones for loading and unloading all my equipment and machines.

The drive up to Sydney turned out to be well worth it – I’ve been to the show a few times before, there is always plenty of fascinating machinery and equipment displayed, but who would’ve thought to win a 10K Digga voucher – we had a really good time.”

99K raised for Ovarian Cancer Research


Only $792 to reach our goal of $100,000 in donations for the Ovarian Cancer Research foundation in 2019.

Through combined efforts with the very generous earthmoving industry, Digga Australia together with Kanga Loaders, so far, we’ve been able to raise over 99K. 

The fundraising started in March when we sponsored and helped organise the Diesel Dirt and Turf Expo Golf Day. Over 30K was raised through charity auctions and the generosity of everyone involved. This was followed by the donation of a Kanga Loader which was auctioned off at the DDT Expo in May. In June we donated a second machine which was auctioned at the Hire 19 tradeshow in Melbourne in June. Finally, a few dedicated Digga employees participated at the Bridge to Brisbane Charity run last month, where another $3,740 was raised in donations.

The Ovarian Cancer Research Foundation was chosen as a partner charity of Digga, a foundation dedicated to developing and implementing an early detection program and improving the mortality rate, management and long-term survival of women with ovarian cancer. As the company suffered a big loss in June 2018, when Suzie Wright, CEO and Managing Director of Digga Australia and Kanga Loaders, passed away after a long struggle with a rare form of ovarian cancer, this is a very close cause to our hearts.

With only $792 remaining to our goal, you can make the difference! Want to donate towards our chosen charity? Please contact us via 1300 2 DIGGA or at info@digga.com

Digga tips - when to rotate picks and change the teeth in your auger.

You will at some point need to replace your auger teeth, when is dependent on how often they are used, how they are looked after and the ground conditions they are being used.

However, the teeth on your auger should be changed as soon as reasonable wear is noticed and before any pocket wear occurs. The productivity of the auger will decrease as the efficiency of the teeth wears.

The outside teeth are travelling the greatest distance as they follow the rotation of the circumference of the augers diameter so they will wear out much quicker than those towards the centre. This is because they have not been travelling as greater distance. The most common sign of wear is to the outer tips of the tooth and this wear will follow the radius of the diameter.

If you continue to wear through your outer teeth, you will begin to wear into the pockets and the flights of the auger.

It is important to check your teeth regularly to work productively and efficiently.
If you find yourself in a remote location and unable to replace your worn teeth right away, try swapping the inside teeth closest to the pilot with the outside teeth so you can continue to work until you acquire new ones.

You should also regularly check the pilot. If the pilot is worn and cannot effectively penetrate the ground then the rest of the auger will not be able to do its job. It is important to replace the pilot when wear is apparent on the tips.

Check out our article "Digga tips - best practices for increasing the life of your wearparts"

Below are a number of images which show different levels of wear to teeth.

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.

      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 peice shaft design ensures there is no increased load on the bearing. The bearings do the job they were designed for, efficiently maintaining axial and side loading.

      Extensive warranty

      With a 3 year motor warranty and 5 year gearbox warranty, our drives are backed with outstanding quality.

      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. 

      You can find more advantages of the installation of screw piles here

      Digga tips - the importance of vertical alignment when drilling.

      Digga machinery attachments
      Having trouble drilling? The correct vertical alignment of your auger into the ground is essential to ensure efficient & effective drilling with your excavator. The natural arc movement of the boom causes the dipper arm to move out of alignment as it is raised or lowered, which is why constant operator adjustments are required to maintain vertical alignment. Please consider, that failure to do so will create significant side load on the auger drive and auger!

      As 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. When you are drilling especially into hard ground this may also  cause socket and pilot breakage. So make sure to align your auger and drive correctly, to avoid damager and drill which much better performance.

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

      G'day Digga - An article by the Earthmovers Magazine

      Digga is as Aussie as the phonetically spelt name suggests. Solidified as our country’s leading machinery attachment manufacturer and exporter, the company still remains proudly Australian owned and operated. Let’s dig a little deeper into this national treasure as we salute a true blue Industry Leader.

      The company experienced extreme progression and growth in their first decade as their range of products steadily increased, including the manufacture of their own world-class gearboxes. While Stewart continued to build a strong team of expert professionals around him, he also improved Digga’s internal manufacturing processes with the introduction of computerised machining, robotic welding and more advanced steel cutting equipment to their assembly line.

      After establishing themselves in Australia, Digga began exporting their quality products and gaining a reputation overseas, firstly in New Zealand and Europe in 1997 and then in the US in ’99. In 2006 the company moved into their own $5 million, fully purpose-built headquarters and factory at Yatala, located halfway between Brisbane and the Gold Coast.

      After an electrical fault sparked a devastating fire in 2016, Digga completely rebuilt their 12,500sq/m facility into a state-of-the-art manufacturing plant equipped with the latest fabrication, manufacturing and high production welding technology. They now have branches in Brisbane, Sydney, Melbourne, Perth, UK, New Zealand and the USA with more than 450 dealers world wide.

      “Digga now sells over 70 different attachment ranges, exports to over 50 countries and employs almost 250 people in three company- owned facilities around the world,” proudly boasted Alan Wade, Digga Australia’s CEO. From initial design, to sourcing raw material, to manufacturing the end product, Digga has always been uncompromising in their dedication to providing the highest quality, competitively priced attachments that are made super durable for Australian conditions and for the Australian market.

      “Digga has built a reputation based around quality and innovation for almost four decades,” Alan stated. “The Digga name is synonymous with the earthmoving industry, but what really sets us apart
      is quality. We see auger drives come in for service that we manufactured over 20 years ago.”

      Always looking to make improvements and stay ahead of the game, Digga’s research and development is second-to-none. Having a locally-based R&D Department is something that is (unfortunately) quite rare in Australia. With a dedicated division of engineers and technical staff, they come up with their own original, cutting-edge designs and functionality improvements, and fully test performance optimisation.

      Using leading software, finite analysis and 3D modelling technology, Digga’s R&D Department is able to maintain a competitive edge by greatly reducing the cost and time of developing new parts and products. Among a plethora of breakthrough inventions and accolades, Digga won the Australian International Design Award for its revolutionary and patented Swing Control System, which increases safety by stabilising drilling machinery during operation.
      On top of their Australian designed and built attachment products, Digga also has an extensive range of wear parts and offer spare parts servicing with in-house and onsite service vehicles in operation. "Our greatest difference is Australian made quality and service,” continued Alan. “Being Australian made means that we better support our product. Spare parts are on the shelf; no need to wait six weeks for them to arrive. Digga is a one-stop shop. No other company offers such a wide range of products. This means that dealers only need to deal with one company instead of two or three.”

      While Digga’s momentum continues to move forward, it’s not all smooth sailing with some obvious uphill battles to face. “The biggest challenge for Digga is competing against cheap import products,” freely admitted Alan. “Digga has been committed to supporting Australian workers and the local industry over the past 38 years by keeping manufacturing in Australia, but this comes with its  challenges. We’re continually improving our manufacturing processes and attachment designs to ensure we produce them efficiently to enable us to compete on a similar price point. We have to be 25 per cent better at what we do to offset the cheaper labour and costs associated with manufacturing in some countries.”
      Never one to compromise on quality or rest on their laurels, Digga promises that they are going to be making even more headways with some groundbreaking advancements in the future. “We’ve got some exciting products coming out in the next 6 to 24 months,” Alan revealed, “as well as continuing to roll out improvements to existing products. We see significant growth in some of our export markets, which are all fed from our main facility in Queensland.

      While wireless technology has been introduced into several products to make them easier to use, the biggest technology shift is yet to hit us. Electric power will have a big change on our industry.” With their 40 year anniversary around the corner, watch this space as things are only going to get bigger at Digga.

      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.

      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:

      BGL Solutions favourite Digga Attachment - The Digga Power Rake



      Bruno from BGL Solutions has worked with Digga Attachments for a long time, take a look at which attachments he uses for his Landscaping business and find out why the Digga Power Rake is his favourite tool:

      “I’ve been involved in Landscaping at an early age back in Portugal, where I grew up, and always used to work with Digga attachments there too. When I moved to Australia in 2008, I started my business BGL Solutions in Katanning WA as a garden maintenance business. As we grew over the years, we started buying more and more machinery and equipment for landscaping.
      Today the business has grown to a reasonable size with a mini loader, an excavator, a skid steer loader and big industrial mowers. The Digga Attachments that we own are the Digga Power Rake for our skid steer as well as 250mm, 600mm, and 900mm augers, a bucket broom, a stump grinder and a trencher for our mini loader.


      The first attachment I purchased for BGL Solutions was a Digga Stump Grinder. I’ve been very happy with it over the years, other than some wear and tear issue here and there – but Digga West, especially Sean and John, have been very helpful over the years and always willing to provide the best solution.

      BGL Solutions carry out a variety of jobs in Landscaping, including tree planting, turf preparation, asbestos removal and more. All within a 350km radius, so we are very remote between Perth and Albany. 

      Most of the jobs are government related, but currently we are working on a massive project in Katanning, which involves a lot of work with our Digga Power Rake, probably my favourite attachment! For this project, we use the Rake to remove old turf, prepare the soil and replace with new turf.

      We’ve carried out a lot of work with the Power Rake on our Terex PT30 in the past. Awesome tool for a landscaper: it level yards, spreads soil, rejuvenates old gravel driveways, prepares soil for new turf/seed, removes small debris from site leaving the soil behind, detaches turf and much more. Just awesome. I’ve had mine for 6 years and no issues with it.

      Why I chose Digga? To be honest, I always like to buy, what I think is most suitable for my needs. I do my research and find the best ones on the market. Value for money is key – cheap is not good – I my opinion it is worth paying a little extra for great quality attachments. Plus, Digga attachments come with an excellent backup in terms of service and support." Bruno from BGL Solutions

      Digga tips - best practice when drilling in rock.

      Are you having trouble drilling in hard rock? We can help you out with some tips to make your job easier.. and more efficient! Without damaging your drillhead or wearparts.

      Let us explain why rock drilling may cause difficulties and issues when not carried our correctly: When drilling rock or frost for extended periods of time, air is trapped in the hole creating an oven effect. The trapped temperature and friction causes the wearparts and pilot to heat up to an extreme temperature, causing them to melt. It will damage the drilling head and can result in the face of the rock to 'glaze over' and become an even harder surface. This is why we recommend that you periodically remove the auger from the hole to allow fresh air back in the hole every 5 minutes. This means - stop drilling and bring the auger head to the surface to allow air into the hole.

      Below is an example of an auger, which was left down the hole for too long.


      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 air back down, which consequently 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, which will make the spoil easier to remove. However 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.

      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.

      • DozingWith 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.

      Why choose a 2-speed drive over a single speed drive?

      Digga Australia - 2 speed auger drive - Australian Made
      If you’re working with multiple sized augers or often in different ground conditions you’ll understand the expense and time wasted that comes with needing multiple drive units for the different applications.

      When the ground is soft you want a higher speed to get the hole drilled quickly and then move onto the next one. When the ground is hard or you’re using a large auger you need torque to get the job done efficiently.

      Speed and torque are always a trade-off; when you increase your speed you lose power and when you increase your power, you lose speed. Similar to a manual car, fourth gear allows speed but struggles with the power required to get the vehicle up the hill

      Standard, single speed drives are typically manufactured as a cost effective solution to provide a speed and torque to suit most applications but will give you one or the other.

      2 speed auger drives have grown in popularity over the last few years and, as leading manufacturers, we can understand why.

      We understand that for our customers time is money and so, our range of 2 speed drive units have been designed to help you work more efficiently - providing you one drive to operate in all conditions.

      The two speed drive is ideal for anyone who drills in a variety of different ground conditions and with a range of different diameter augers.

      As the name suggests, two speed drives have two speeds in one unit:
      • Low-speed high-torque setting and,
      • High-speed low-torque setting

      The Digga 2 speed drive units give operators the option to switch between power and speed. Rather than needing 2 drives (1 for smaller diameter augers and softer grounds and 1 for larger diameter augers and harder grounds), the Digga 2 speed drive unit gives operators both functionalities in one drive.

      Features and benefits of the Digga 2 speed drive range

      There are a number of key features and benefits of a 2 speed drive over the standard single speed, such as:
      • Save time and money by eliminating the need for multiple drive units
      • 2 speed drives are made with Eaton motors and Digga made gearboxes. The electrical plugs are high quality waterproof "Deutsch" connectors offer superior corrosion protection and waterproof properties.
      • 2 speed drives allow for quicker drilling with a small auger and in soft grounds, and more torque for drilling with a large auger or in hard ground.
      • Switch to high speed for faster spinoff of spoil on a high torque drive
      • The low speed / high torque setting is ideal for drilling in fracturable rock; higher RPMs in rock cause the teeth to “skate” over the rock making it glaze over and become harder.
      • The host machine can run at a lower engine RPM on certain drilling jobs therefore burning less fuel
      • With the same gearbox as a single speed drive, it is the same cost to service as a single speed drive unit.
      • By drilling quicker, the job is finished faster so you can move onto the next job
      It’s important to remember that single speed drive units have suited the market for over 30 years and unless you are working with multiple-sized augers, in different ground conditions regularly a single speed drive unit remains a very adequate option.
