The B20 is a compact and balanced stump grinder that can be used to grind down all types of tree stumps, weighing only 120Kg it’s easy to manoeuvre between jobs. With an 810mm sweep but a width of just 680mm, this is a really versatile machine.
The pivot joint between the stump grinder and the wheel axle ensures easy and smooth grinding, even under difficult conditions.
The brakes can be applied individually to each wheel, so the machine can easily access the stump even if there are shavings in the way. The individual brakes can also be used to negotiate steps with ease.
The actual stump grinding is executed by making small manual sideways movements of the stump grinder into the stump. It is extremely easy to move the machine sideways since only the grinding section moves and not the wheels. All sideways and up/down movements are executed manually with both hands on the handlebar. A centrifugal clutch transfers energy from the V-belt drive to the cutting disc.
