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

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.

How to Replace DR Auger Rock Picks (Dedicated Rock Augers)

-
Image
Rotating rock picks, are the auger teeth used on our Digga dedicated rock augers (DR) for drilling from soft rock to hard fracturable rock. Here are some things you can observe to determine whether the rock picks are worn: The teeth need to rotate while drilling to maintain an efficient cutting tip. The tungsten tip and tooth should be evenly pointed. Poorly maintained teeth reduce cutting efficiency and wear out faster costing time and money. We recommend you replace worn teeth immediately! Tip: the outside teeth (C) will wear the fastest as they are travelling the greatest distance so 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. Here are some examples or rotating rock picks in various states of wear. Tooth A has not been rotating in the pocket and as a result the tooth is uneven and will cut poorly. We recommend changing this tooth. You may also notice if the tungsten tip has...
