Be a good mate and ask R U OK

Did you know that tradies are twice as likely to commit suicide than other people in Australia? Statistic surrounding suicide and mental health within the construction industry are quite confronting.

In this male dominated industry people are often asked to ‘toughen up’ with negligence of possible consequences and people’s feelings, what is happening in their lives and why they might be feeling depressed or not themselves.  

And let’s face it. It’s been a rough couple of months for everyone during this pandemic with impacting changes in both our work and personal environment. Which is why we should all be looking out for each other and let our mates know that it’s okay not to be okay.  

At Digga we want to encourage you to be a good mate and ask ‘R U OK’. As part of R U OK day we want to promote awareness for people that may be at risk of mental health issues or potentially suicide in our community. 

Here are some useful tips on how to ask R U OK, as well as how to act when we’ve been told “No, I am not ok.” Follow theses 4 Steps (Source:

1. ASK R U OK?

  • Be relaxed, friendly and concerned in your approach. 
  • Help them open up by asking questions like "How are you going?" or "What’s been happening?"  
  • Mention specific things that have made you concerned for them, like "You seem less chatty than usual. How are you going?" 


  • If they don’t want to talk, don’t criticise them. 
  • Tell them you’re still concerned about changes in their behaviour and you care about them. 
  • Avoid a confrontation. 
  • You could say: “Please call me if you ever want to chat” or “Is there someone else you’d rather talk to?” So, make sure to look after your employees, your workmates as well as your boss. If you notice something’s not right, don’t be afraid to approach them and ask whether they are doing ok. 


  • Take what they say seriously and don't interrupt or rush the conversation.
  • Don’t judge their experiences or reactions but acknowledge that things seem tough for them.
  • If they need time to think, sit patiently with the silence.
  • Encourage them to explain: "How are you feeling about that?" or "How long have you felt that way?"
  • Show that you've listened by repeating back what you’ve heard (in your own words) and ask if you have understood them properly.


  • Ask: “What have you done in the past to manage similar situations?”
  • Ask: “How would you like me to support you?"
  • Ask: “What’s something you can do for yourself right now? Something that’s enjoyable or relaxing?”
  • You could say: "When I was going through a difficult time, I tried this... You might find it useful too."
  • If they've been feeling really down for more than 2 weeks, encourage them to see a health professional. You could say, "It might be useful to link in with someone who can support you. I'm happy to assist you to find the right person to talk to.”
  • Be positive about the role of professionals in getting through tough times.


  • Pop a reminder in your diary to call them in a couple of weeks. If they're really struggling, follow up with them sooner.
  • You could say: "I've been thinking of you and wanted to know how you've been going since we last chatted."
  • Ask if they've found a better way to manage the situation. If they haven't done anything, don't judge them. They might just need someone to listen to them for the moment.
  • Stay in touch and be there for them. Genuine care and concern can make a real difference.

If you’re worried about your mate and have a feeling they need professional support, encourage them to connect with a trusted health professional like their doctor or other support like Lifeline at 13 11 14. Further support tools can be found here:

The Latest Auger Alignment System on the Market - HALO

Now available Digga Halo Auger Alignment System

Have you heard of HALO, the biggest innovation in pendulum drilling in the past two decades? HALO is Digga’s brand new Auger Alignment System. 

HALO has been designed to save operators time and money. It helps you drill straight holes and therefore provides a number of advantages to the earth drilling industry.

Its benefits include, amongst others, reducing the number of in-hole angle adjustments which can create an oversized hole, also reducing the amount of concrete required to fill the hole. Not drilling straight can additionally cause sideload on the auger bit and drive, potentially causing damage and expensive repairs. With HALO operators drill more efficiently, as you can return to drilling faster after returning the auger into the hole.

Another great advantage is you won’t need a spotter with a spirit level guiding you through the hole. So, if you’re trying to save on labour costs, HALO is the way to go - remember HALO does not take holidays or sick leave!

Digga Halo Auger Alignment System

So, how does it work?

It’s simple: Chase the Green, Live the Dream!

A band of green LED lights indicate when the unit is in a plumb position, while a sequence of red and green lights guide you back to plumb when the unit goes out of alignment.

HALO has been programmed to show all green LED from 0°to 1.5°of incline. After 1.5°the LEDs will show a sequence of red and green lights.

These lights move around the hood to indicate which way to move the drive to return to plumb. The red and green lights are always opposite each other, thus if the operator can only see the red light, he or she will surmise the location of the green and be able to “chase” it.

Digga Halo Alignment System- chase green LED lightsWhat components is HALO made up of?

The brains behind HALO lie in the hood box, which is situated inside the hood. It includes 6 sensors to accurately measure inclination to +/-.25°. HALO utilizes a microprocessor and “Sensor Fusion” to bring together inputs from multiple sensors to form a single output which is more accurate and less prone to false readings than single sensor models.

A one-piece LED ring made from polycarbonate will allow you to see the HALO from a distance and also in bright daylight. The LED lights are a high-resolution single die LED strip featuring 3 LEDs per pixel. The LED strip is then covered by a polyurethane compound making the whole unit dust and waterproof. It’s then recessed into the hood ring to protect it from damage and the bottom ring is bevelled to allow better visibility of the lights when the drive is being used with long extensions.

A lead-in power cable, which extends around 200mm from the hood, allows you to power the HALO. This then gets connects to either a power cable & extension back to your cab’s cigarette lighter or to a HALO battery, which lasts up to 8 hours. The lead-in cable has a yellow sheath to make it more visible to the operator and can easily be tucked into the hood when transported or stored.

How does HALO compare to other alignment systems on the market?

There are several advantages of incorporating an alignment system into the hood. It costs significantly less than traditional systems by eliminating the need for a costly in-cab display screen. 

In-cab display screens also require you to constantly take the eyes of the job, which is unsafe and tiring over time. HALO sits right in the hood of your drive (above the auger and drilling hole), so it is highly visible while drilling. We consider HALO to be an upgrade from existing technology on the market. Why use outdated technology when there’s more affordable and effective options, right?

Research, Development & Testing

Since its inception in 2016, HALO has gone through a wide range of testing and design upgrades to ensure the product taken to market works as intended, is free from defects and is durable. Some of the tests have included, water, vibration, and heat testing as well as longevity testing.

Over 50 units have been out in the field with customers since November 2019. Very few issues were reported with all concerns rectified with our latest version HALO.

Digga Halo Testing

These are some comments we have received from our Testers in the last couple of weeks: “Would be lost without the HALO, I would dig over a couple of thousand holes a year and this has sped up time and production.” – Ritchey Fencing.

“The main benefit I get out of it, is that it takes away the need to use another operator guiding me through the holes. This really saves me a lot of labour costs.” – Bobs n 2 Sons Excavations.

Why is it important to drill straight? And what happens if you don’t?

Auger drives are pendulum drills designed to hang freely from the machine mount. You need to consider, that 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. HALO makes sure you are aligning your auger and drive correctly, to avoid damages and drill which much better performance.

BONUS WITH BATTERY: Zero-ing Function lets you drill at an angle!

For those of you, who are often required to drill on an angle for e.g. installing retaining walls or shade sails there is another bonus the HALO brings. With the purchase of a battery pack, the HALO can be set to a desired angle in inclination just by the click of a button.
So, let’s sum it all up. 

Why do YOU need HALO?

  • Drill straight and avoid side loading your auger, causing damage 
  • Never take your eyes off the job
  • No more in-hole angle corrections - use less concrete
  • Reduce costs & increase efficiency - no need for a spotter
  • Realign the auger faster when re-entering the hole - save time
  • Easy and no-fuss setup 
  • Drill at an angle with the battery option

The HALO system is out now for new Digga Drives PD3 to PD7, which suit most machines like skid steer loaders, mini loaders, tractors, and excavators around the 3 to 8 tonne range. We are looking at releasing HALO to their entire range of drilling drives in late 2020 and will be re-assessing retrofit options in the future.

Digga Tips - Servicing and Oil Change of your Digga Drive Unit

To ensure longevity and performance, it is crucial to service your Digga drive unit and change the oil in regular intervals as advised in the operator’s manual. While you might be wondering why, we have got all the answers for you.

When do I need to service my auger drive?

As advised in the operator’s manual, here is an overview of when to service your drive depending on your operating conditions.
When to Service Your Auger Drive Intervals

Why is gear oil important to ensure the longevity of my drive?

Essentially, the oil in your drive unit is independent to your hydraulic system. Meaning that the 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 and to avoid damage to the gears.

What happens if my auger drive is not serviced regularly?

We have tested 3 drive units 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. 
The images below illustrate the importance of regular servicing of your auger drive and what happens if failed to do so.


This is a gear from a drive which has been serviced as per the operators manual and shows very little wear with no more than bedin wear after 10 years of simulated augering. The oil was changed after 12 months and then every 2 years thereafter as per the operators manual.


The same drive submitted to the same workload as above over 10 years, with the oil changed only once - at 5 years. While the drive unit shows no decrease in performance, the gear shows visible wear which will deteriorate quickly, leading to total failure.


This drive has never been serviced. The image shows the damage to the gear, which causes total failure of the gearbox.

At Digga we offer ISO 320 Grade Mineral Oil in 1 litre, 2.5 litre and 5 litre containers.

Now also available: DIY Service Kits for Auger Drives from PDD to PD50!

How to Operate A Digga Bucket Broom

Having trouble operating your Digga bucket broom?

There are a few tips and tricks when it comes to brush adjustment & height, rotation direction and the broom emptying procedure. We've summarised them for you below.

Direction of travel and brush rotation

Always sweep at a high enough brush speed and low ground speed to effectively discharge the material being swept.

Brush height adjustment

Remove the handle pin, twist the handle, and replace the pin. Re-adjust the axle to the correct height using both handle adjusters. Return handles to their original position.

Correct Brush Height

Set the height of the brush so the bottom of the brush is approximately 30mm lower than the bucket cutting edge. The brush must be level.

Emptying Procedure

When the bucket requires emptying, stop the rotation of the brush, lift your loader arms and crowd the bucket forward so the Bucket Broom hood swings away from the bucket.

Examples of Damaged Bucket Brooms due to Incorrect Operation

If not used correctly, damage and expensive repairs can occur to the Digga bucket broom attachment. Below are some examples.

Broom 1 – Worn side rubber and side panel due to too much downward pressure and incorrect placement of the broom to the ground during operation.

Broom 2 – Worn Brush, starting to wear side panel.

Broom 3 – Worn the cutting edge (wear strip) to the point that the floor has started to wear away and edge is now non-existent. New bucket floor is required.

Broom 4 – Brush has been lowered to its maximum wear point and is now out of thread, a new brush is required.

Broom 5/6 – Strong wear to the rubber and side panel due to too much downward pressure and incorrect placement of the broom to the ground during operation.

Please always make sure to read the operators manual before operating your attachments! Should you have any questions, please don't hesitate to contact us anytime at 1300 2 DIGGA.

In honour of Suzanne - Ovarian Cancer Awareness Month

When Carla’s mother, Suzanne discovered she had Stage 4 Ovarian Cancer in November 2012, her family support team flew into action.

In the three years that followed, Carla, her siblings and her father were by Suzanne’s side as she faced an operation, chemotherapy, and tried every natural remedy or treatment that was available. Throughout all this, Suzanne planned big holidays every year, to all the places she had always wanted to go.

Sadly, Suzanne passed away at the age of just 66.

Today, Carla works in the family business that was founded by her parents, Krinklewood Biodynamic Vineyard in the Hunter Valley.

“For the past few years I have thought about trying to raise some money for OCRF but just didn’t feel ready to stand up and talk about it with our members, but this year I decided I could do it. I really wanted to do it in honour of Mum, and to help support all of those currently going through Ovarian Cancer.”

Each year, the vineyard restaurant holds a members luncheon. This year, Carla added $20 to the ticket price and advised attendees that this would be donated to the OCRF.

“I had some really lovely generous local businesses support us by donating prizes for a raffle, and on the luncheon day we sold raffle tickets to our guests. Also over that whole weekend we popped a sign up in our cellar door, advertising that were donating 5% of our weekend cellar wine sales.

“Carla’s amazing efforts to date, have raised over $17,000 for the OCRF. It is Carla’s hope that these efforts will help the quest to find an early detection test. “Particularly when there are 3 granddaughters in our family and my sister and myself.”

Carla said she was very proud with the end result, and she certainly has every right to be.

We have no doubt that your Mum would be very proud too, Carla.

When to replace Trencher Wear Parts

Keeping on top of your Trencher wear parts will prolong their life and keep you working efficiently for longer! So, when should you be replacing Trencher teeth? How do you know they are worn out?

At Digga we have two different tooth options. Have a look at the description and images below.
  • Tungsten Carbide Teeth: once the carbide at the tip of the tooth is gone, the tooth is ineffective. 
  • Cup teeth: once the tip starts wearing back through the tooth and you’ll notice some hard facing – that's when it will start to inhibit the ability of the chain to penetrate the ground.

Consequently, you will be labouring your machine and burning extra fuel. Make sure you exchange your wear parts regularly to avoid working inefficiently.

Further maintenance checks on your Trencher Chain
Whenever you replace teeth make sure to check your bolts as well – you don’t want to risk losing the teeth by re-using worn bolts.

Check all your spacers, make sure there is no fatigue or wear.

Check the bottom of your chain and inspect the rollers, which are also wear-points due to the constant contact of the drive sprocket and nose roller.
We recommend you take your time each day before going out to a job, to carry out these small maintenance checks – you don’t want to get caught in the middle of a job with a break down that’s going to end up impacting your performance on the job!

Got questions? Contact our service department at 1300 784 223 or get in touch via

Feel free to watch our video with Anthony, Digga Sales Manager, taking you through the most important points to consider.

Maree’s Ovarian Cancer Journey at age 21 - Ovarian Cancer Awareness Month

Maree Taifalos was just 21 when she was rushed to hospital with severe abdominal pain. She underwent surgery a couple of days later for what everyone thought was a large cyst, but what was in fact dysgerminoma—a rare type of ovarian cancer.

“A week after surgery, I was told about the chemotherapy. It was a particularly strong type that was developed earlier that year. Three cycles, each one three weeks long, with the first week being five days of treatment in a row. It made me so sick. I would barely be able to walk to the car from the hospital. I would be so nauseous that the smell of food passing my room to get to other rooms would make me vomit.

But throughout it all, I had some amazing support around me. My parents never left me alone in hospital and would juggle work and my siblings to always make sure I had the best care at home. My brother took on so much more in the family—he was at university at the time so I don’t know how he managed it, but he’s a pretty special person. My little sister was very young, she was scared because she didn't understand what was going on but she motivated me to finish my treatment. And the nurses—they would sneak blankets and mattresses into my room so Dad could sleep on the floor.

While having my treatment, I didn’t know a single person with cancer younger than my grandparents’ generation. I had no idea what I was in for with treatment but, more importantly, I didn’t know how quickly I would heal and that my life would return to ‘normal’.

By November that year I was in remission. My skin had returned to normal, my hair had started growing, I’d started back at work and was planning on going back to university as soon as I could. I found out that I’d be able to have children, even after everything that my body had been through. That was a big relief for me.

This July marks nine years in remission. Since then, I've finished my studies and have been practising as a lawyer for the past four years.

It’s taken a while for me to be able to talk about my experience and to be able to reflect on the last eight years. I like to think my life’s ‘normal’ now but maybe a bit better because I know I’m lucky to have come out the other side of an ovarian cancer diagnosis relatively unscathed. I was one of the lucky whose ovarian cancer was picked up in the early stages. With an early detection test, my prognosis would be the norm rather than the exception. That's why I'm supporting the OCRF.”

Ovarian Cancer Awareness Month - Kate & Sue

"Kate lost her sister, Sue, to ovarian cancer seven years ago. She was in her mid-40s and working as a kindergarten teacher. Like too many women with her lethal condition, she had no symptoms.

In fact, by the time she was diagnosed and treated, doctors told her that her tumour could have been there for two or three years—the silent killer.

For Kate and Sue, ovarian cancer runs in the family. Their grandmother had died from it decades earlier. Now, Kate is taking part in the Silver Lining Ride to combine her passion for cycling with her determination to spread awareness."

Installing fences with Digga machinery attachments

Fencing of any kind; whether you’re installing a security fence, garden privacy fence, flagpole or replacing old fence posts, will need you to dig out post holes.

Using a shovel is time-consuming and labour intensive; you will possibly make your hole larger than you need and most probably do your back in.

Digga has a range of attachments and tools to make digging post holes easy when fencing. Suitable for attaching to a mini loader, tractor, skid steer or excavator whether you’re in a garden, on the farm or on building site – we have the attachment for you and/or your team.
Don’t have a machine? We have a one-man post hole digger.

Digga ramdrills:

If you’re working with a tractor, Digga manufactures a range of ramdrills. Digga ramdrills use the 3 point linkage at the rear of the tractor to connect and each option offers different levels of power suited to the different levels of usage and requirement;

Digga manufacture 3 options of ramdrill:

  • PHD ramdrill - the safest most powerful planetary auger drive attachment for tractors. The hydraulic gearbox gives you the greatest power for drilling with maximum down pressure. This model is recommended for larger diameter holes and hard ground or, if you are drilling a lot of tree holes, fence posts holes or general boring with the tractor.
  • PTO ramdrill – uses the tractors PTO to drive the auger through a gearbox and clutch system and it ideally suited to 50 and 75hp tractors. A hydraulic ram provides down pressure for efficient drilling.
  • 3 point linkage drill – the 3 point linkage drill is Digga’s starting model. It is best suited for the farmer who drills the occasional post or tree hole. The borer features a heavy duty frame and uses gravity to penetrate the ground. No hydraulic connections required.

One man post hole borer:
The Digga one-man post hole borer is a practical option if you’re working alone. It collapses into 5 sections to store easily and transport in the back of the ute. With rubber tyres, it is also easy to maneuver and wheel about when you’re on site. Powered by hydraulics to give you power, its anti-kickback feature promotes safety when operating and will stop you being thrown about when in use. Similarly, it has been uniquely balanced to aid operation on the uneven ground and the handlebars can be shifted for better control when close up digging.

Digga's auger drive and cement mixers:

For skid steers, excavators, mini loaders or tractors with loader arms, Digga manufactures a range of front mounted auger drives and augers for all ground conditions. From earth augers to dedicated rock augers you will be able to drill post holes up to 4m deep when coupled with one of our auger extensions*.

What’s more, once you’ve drilled the hole with your Digga auger and drive, swap your auger for our mixer bowl and mix concrete to fix your fencing posts without the need to buy or hire a dedicated cement mixer.

Go from drilling to mixing in under 2 minutes. Click here to find out more about the Digga cement mixer.

*4000mm auger extension available for 30t machines and over only.

For more information on our product range ideal for fencing visit the Digga website or watch more videos on our YouTube channel. Alternatively get in touch and we will put you in contact with your local Digga dealer.

Excessive Wear on Rock Augers

Customers often ask us about excessive wear on rock augers. As rock augers are designed to drill through very tough ground and hard rock, we’d like to outline what kind of wear should be expected, why rock augers wear and how this can be avoided to keep your augers operating at maximum performance.

First of all, what types of rock augers are there?

At Digga we offer three variations of rock augers.

The Digga Earth/Rock Combo Rock Auger features tapered tungsten taperloc teeth and is designed for drilling in earth, shale, permafrost and some fracturable rock.

Dedicated Rock Augers on the other hand, come in a standard and Tapered Rock variation, both featuring rotating picks and used to drill in fracturable to hard rock. The design with short flighting and rotating pick pilot encourages regular spoil removal, allowing cool air to enter the hole, and facilitate regular tooth inspection. Additionally, a hard-faced finish is applied to the flight edges and pockets of the dedicated rock augers to insure a longer life.

The advantage of the rotating pick pilot is the ability to build up or maintain body of the pilot while also having the ability to replace worn teeth in an effort to maintain a longer serviceable life.
If conventional augers aren’t getting through the rock, we would recommend trying a dedicated rock auger. If that doesn’t work, the next step would be a tapered rock auger and if the rock is still too hard then a core barrel should be used.

So, why do rock augers show more wear than e.g. general-purpose augers?

Rock augers face a lot of extreme conditions in very tough ground, so naturally you’re going to get a lot of wear. To achieve penetration into the rock, the rock needs to fracture or break into chip. For this to happen the point of critical pressure must be reached and exceed to burst through that hard material. If your machine doesn’t have enough down pressure to push the augers into the ground, the auger starts grinding – if that is the case you are going to experience a lot of wear.

You’re going to see wear on your teeth, flight edging and especially on your pilot. The pilot sits in its own hole at the tip of your auger at about 150mm to 200mm, so a lot of spoil sits around that pilot acting like sandpaper due to the rocks abrasive nature. Because the pilot has teeth, doesn’t mean it will never wear out – it is still a replacement part. The advantage is that you can replace the teeth, or you can rebuild the pockets to get a bit more life out of it.

Another important factor to be considered when drilling in rock for extended periods of time is, that air is trapped in the hole creating an “oven”, which can cause the face of the rock to “glaze over” and become even harder. Drilling in rock for extended periods of time will therefore cause the wearparts and pilot to heat up to an extreme temperature potentially making them melt or fuse in the pocket.

Overall, when drilling in extreme rock, you should generally expect that you are going to get some wear – it needs to be priced into your job. Make sure your customers know that you drill into really hard rock, this comes with tooth replacements, extra wear or maybe some rebuild work on your auger.

How can I tell that my auger has worn?

The images below indicate wear on rotating picks and the pilot.

The tungsten tip and tooth should always be evenly pointed looking like it has been in a pencil sharpener and teeth need to rotate while drilling in order to maintain an efficient cutting tip. A flat spot on the tooth and teeth being locked in, indicates they have stopped rotating. Side wear exposes the carbide, meaning that the carbide tip will eventually drop off. If the tungsten tip has been worn down and flattened, we recommend replacing the tooth. Poorly maintained teeth reduce cutting efficiency and wear out faster costing time and money.


On the pilot you will notice worn rotating picks as well as worn tooth sockets. 

How do I avoid excessive wear?

We’ve summarized the most important rules to help you maintain your rock auger at maximum performance:
  1. Do not use a dedicated rock auger (DR) to drill through earth or clay. This ground prevents the teeth from rotating, causing flat spots and premature wearing of the teeth.
  2. Control your temperature when drilling: Try putting some water down the hole to cool it down and to make the spoil easier to remove. You should stop drilling every 5 minutes, bring the auger to surface and allow air back down the hole. Once spoil has been removed, we recommend a visual inspection of your auger and teeth. 
  3. Use a soft copper or dead blow hammer to tap all teeth ensuring they are rotating freely in their pockets. This will encourage even wear around the tooth. Tip: Don’t touch the picks with your bare hands after drilling, as they’re going to be extremely hot.
  4. Check for slightest signs of flat spots on the teeth every time the auger is removed from the hole. Flat spots indicate a non-rotating tooth.
  5. Regularly remove the teeth and clean pockets with a wire brush. Ideally after each day’s use. Especially if storing for an extended period of time.
  6. Do not use grease or lubricants on the tooth. Mixed with dirt, lubricants form a paste which prevents teeth from rotating in the pockets.
  7. Always clean the drilling head prior to storage. Dirt will solidify overtime making it harder for the teeth to rotate. Rock augers are not a ‘set and forget’. Just like a sportscar – it needs a little bit more maintenance than your family car.
  8. The outside teeth will wear the fastest as they are travelling the greatest distance, so they will need replacing more often. Try swapping the outer tooth for an inner tooth to keep the wear even. Always use your best teeth on the outside pockets.
  9. Replace worn teeth immediately.

Continuous Flight Augers with Removable Cutting Heads

We recently delivered a custom drilling solution for one of our customers, who uses a piling process called Sheet Piling. For this particular application, Digga developed and provided CFA style augers with a removable cutting-head-design and varying lengths.  

What are traditional CFA augers?

Here is some background information: Continuous Flight Augers (CFA) are mainly used for drilling water-bearing sandy soil, sludge, clay, muddy sub clay, sandy gravel, cobble, and weathered soft to hard formation (rock). 

CFA piles are a type of drilled foundation in which the pile is drilled to a final depth in one continuous process, using a continuous flighted auger (CFA). Concrete or grout is then pumped under pressure down the hollow stem of the auger to the bottom of the bore. Once pumping starts the auger is progressively withdrawn bringing the soil with it to the surface, leaving the Concrete/Grout in the pile. Reinforcement (Reo) is then added to the concrete pile for additional strength. 

Variations to the hollow stem style CFA augers, are CFA augers with solid coupling (non-hollow core). They are used to achieve depth in one continuous motion - just like hollow stem - but simply without the concrete/grout injection. It is traditionally used in more stable grounds or over the more traditional methods like rotary piling or utility piling, where the operator drills to top of the flight and removes the auger and spoil from the hole, shakes it off and returns the auger to the hole to drill deeper. This process is repeated over and over, until depth is achieved (tube extensions might be added to drill deeper than the OAL of the auger). This method is slower and more cumbersome and can cause the pile to collapse in unstable softer ground.
Continuous flight augers
So, what was our customer after?

With that in mind, a client who uses a piling process called Sheet Piling (used for excavation support and soil retention), came to Digga for a solution to an issue they faced with pile run-off, meaning the sheet pile was deflecting when hitting hard ground as the sheet was unable to achieve penetration.  

The client requested augers for pre-drilling to loosen the ground before sheet piling. Pre-drilling enables the sheet pile to be driven to depth without deflection. So, our customer challenged us to come up with a cost effective and versatile solution to their drilling needs.

Wanting to drill to a depth of 12m and everything in-between but minimising the logistics of material handling on site of multiple 6m long augers and the versatility of being able to drill all ground conditions from Earth to Rock.

Our solution

Digga developed a CFA style auger using solid hex drive hubs and shafts. Utilising the CFA-design, it provides the ability to reach depth in a continuous process. The package Digga provided to the customer consisted of two 3-metre long and one 6-metre long CFA sections, which allows for greater depth flexibility.
Continuous flight augers
This means that the customer has the capability of various depth options from 3m, 6m, 9m up to 12m, coupled with Pin-On or Removable heads (REM). This way, the client can change from an Earth Auger (A series) to a Rock Combo (RC Series) to a Dedicated Rock (DR Series) within minutes.

Not only do we have the advantage of being able to change cutting styles quickly, it also means that there is no need to fit, remove or refit the auger sections from the host machine, when requiring a change to the cutting head style to meet the varying ground conditions.
Continuous flight augers
Overall, this resulted in saving manual labour charge and safer material handling on site.

This multipurpose auger package was coupled to a Digga PD50 two-speed drive complementing the total cost effective, cost saving and flexibility of the package.

Digga tips: drilling in clay

When you’re drilling in clay it can be difficult to remove the spoil off of the auger.

It’s tempting to alternate the drive from forward to reverse to flick the clay off, but this can cause serious torque related stress on the drive gearbox which will lead to premature failure and subsequently expensive repairs.

Hitting the auger against the ground can also create side load on the shaft which could in turn damage the shaft seal and gear box.

In our previous blog post we explain the best way to remove spoil from your auger; using a forward, stop, forward, stop control pattern. This can often take a long time when working in clay and time costs money…

Here are a number of tips to help remove the spoil from your auger when drilling in clay:

  1. Drilling another hole with the clogged auger and then reversing out of the hole will remove soil from the flights
  2. Using a single carry flight auger to avoid the clay becoming compacted between the flights
  3. Choose a steep pitched auger flighting so that the soil can slide off easier
  4. Wet the auger before it goes into the hole, WD40 and soapy water can also work well.

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.                                                                       


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.
