What to do with the stump?

Traditionally stumps have had to be dug out, digging out stumps manually is hard work and very time consuming some people with a very small stump in there garden may wish to dig it out by hand, but anything but the smallest stumps would need to be dug out using an excavator. This is much faster than digging by hand but is also expensive and will cause collateral damage to the area again causing more work. In some situations, it may not be possible to access the offending stump with an excavator. This is where the stump grinder comes in handy!


What is a stump grinder?

A stump grinder is a mechanical device designed to solve the problems described above. Stump grinders are available in several sizes from a cut of saw derived handheld machine to machines the size of trucks. Whether big or small the stump grinders work in a similar manner.

How do stump grinders work?

Stump grinders are equipped with metal teeth these rotate at 1000s of revolutions per minute, grinding away at the stump like thousands of little chisel blows. Most stump grinder teeth are made with a carbide cutting tip or entirely from carbide, this incredibly hard material is perfect for grinding away at the stump, most stump grinder teeth can be sharpened several times before have to be replaced.  Stump grinders in most cases are powered by petrol or diesel engines these in turn power the stump grinding wheel either via a belt drive system as you would on a smaller pedestrian machine or hydraulically driven in the case of bigger stump grinders. Other stump grinders operate with the same stump grinder wheel design but powered by the PTO shaft on a tractor.
