The FSI B21 is a compact, efficient stump grinder, designed for arborists, tree care professionals, and stump grinder operators needing reliable performance, easy transport, and hassle-free stump grinding.
FSI B21 offers improved efficiency, optimized operator comfort, and simplified maintenance.
With the FSI B21, we raise the bar by introducing unique features not seen before in this segment.
- Hill-hold system – Never worry about your stump grinder rolling away on ramps. The innovative braking system ensures safe and easy transport up ramps, over steps/curbs, and on uneven terrain. When activated, the stump grinder can be pulled backward safely without the wheels rolling forward.
- No daily maintenance – The closed bearing housing is pre-lubricated for over 1000 hours of normal operation, eliminating the need for daily lubrication and reducing the risk of over- or under-greasing.
- Simple V-belt tensioning – The FSI Power-Cut cutter disc is mounted with a one-sided bearing housing, allowing easy V-belt tensioning without the need to ensure parallelism.
- Turn-table design – The turn-table design makes sweeping the cutter arm from side to side effortless, reducing strain and increasing precision for the operator.
Key Features:
- Narrow 68 cm width
- Vibration-damped and height-adjustable operator handle
- Safety bar disengages the cutter wheel when released
- FSI Power-cut cutter wheel
- Turn-table design (pivoting axle) – ensure effortless side-to-side sweep
