Welcome to the Digga blog

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. So which auger should you choose for your application?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.  As a general rule we recommend the following RPM/speeds: 55-65 RPM for general earth conditions. 45-55 RPM when drilling in heavy earth, clay or shale.  20-45 RPM when drilling in rock. Results will depend on rock hardness, type of auger being used and machine down force.  Digga recommends the following for attachments for the different ground c...

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.

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 r...

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...

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...

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. For more information on the Digga Service offering visit  www.digga.com/service-spares

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 co...

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 u...

Level cut excavations Doug Sparkes is the owner of family run business Level Cut Excavations in Hastings, Victoria. His company can do any kind of earth moving or excavation and specialise in screw piles and bored piers. Doug uses the Digga PD12 fitted with a standard double pin hitch connected to his 5.5 tonne Kubota excavator. To install screw piles to a max torque of 11,268Nm Doug had the Digga ECV retrofitted to his drive. Digga ECV Also known as the swoosh valve, the ECV turns a standard auger drive into a screw anchor drive. In doing so, it protects the gearbox and motor in your drive from the rapid decompression of oil and pressure build up after achieving required torque.  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...
