FSI Stump Grinder For Sale, With FSI B21 we raise the bar and add unique new features not previously seen in this segment. Hill-hold system – Worry no more about your stump grinder rolling away from you on the way up the ramp. A unique braking system ensures safe and easy transport up ramps, over steps/curbs and in terrain. When the hill-hold system is active, the stump cutter can be pulled backwards safely and easily without the risk of the wheels rolling forwards. No daily maintenance – We have developed a closed bearing housing, which is lubricated from factory for more than 1000 hours of normal operation. Therefore, you no longer need to think about daily lubrication of bearings. Simple V-belt tensioning – the special FSI power-cut cutter disc is mounted with a one-sided bearing housing, allowing for very simple tensioning of the V-belt without you having to secure parallelism.
