FSI B21 Stump Grinder

FSI designs the FSI B21 Stump Grinder in collaboration with professional users and FSI partners. As one of Europe’s largest stump cutter manufacturers, FSI follows market needs closely and continuously improves its machines. As a result, the B21 delivers strong performance, high quality, and practical functionality.

The B21 introduces several new features that improve safety, control, and maintenance. Therefore, it suits professionals who need a reliable machine for daily stump grinding.

A key feature is the hill-hold system. It stops the machine from rolling when operators move it up ramps or work on slopes. In addition, it allows safe reverse movement without unwanted forward wheel movement, which improves control during transport.

FSI also reduces maintenance requirements. The sealed bearing housing comes factory-lubricated and runs for over 1000 hours without daily greasing. As a result, operators spend less time on routine maintenance and more time working.

The machine uses a simple V-belt tensioning system. The cutter disc design allows quick adjustment without complex alignment steps. Therefore, operators can service the machine faster and with less effort.

FSI includes proven features from earlier models such as the B20 and B22. The machine uses a 14 hp recoil-start engine, and it features vibration-damped, height-adjustable handles for better comfort.

The safety bar controls the cutter engagement and stops the system when released. In addition, individual wheel brakes improve stability during operation and transport. The turn-table design also helps operators sweep the cutter arm smoothly from side to side.

FSI adds multiple transport features for practical handling. The machine includes several lashing points, a lifting eye, and an optional drawbar for ball hitch transport up to 10 km/h (not for public roads).

FSI builds the B21 with durable components and original FSI teeth for long service life. Optional extras include an hour meter with maintenance alerts and custom paint colours for company branding.

Overall, the FSI B21 Stump Grinder combines safety, low maintenance, and strong performance. It gives professionals a compact and efficient solution for regular stump grinding work.
