The FSI B21 adds unique new features not previously seen in this range.

The Hill-hold system is a unique braking system that ensures easy and safe transport of the machine up ramps, curbs, and steps. With the hill-hold active, the stump grinder can be safely pulled backward without the wheels rolling forward.

The closed-bearing housing, lubricated from the factory for more than 1000 hours of normal use, means no daily maintenance is needed.

Simple V-belt tensioning - the FSI power-cut cutter disc is mounted with a one-sided bearing housing, allowing for simple tensioning without securing the parallelism.

• Powerful 14hp engine with recoil starter

• Vibration-damped and height-adjustable operator handle

• The cutter disc is activated using a safety bar

• Turn-table design (pivoting axle) – ensure effortless work when sweeping the cutter arm from side to side.

• Individual wheel brakes

• Multiple, easily accessible lashing points for simple and fast securing during transport

• Lifting eye

• Original FSI teeth
