The stump cutter is suitable for grinding away tree trunks (stumps) and surface-growing roots. The Herder-Fermex stump cutter consists of a grinder wheel driven by a hydraulic motor. The powerful blades of the stump cutter cut the stump away so that a new tree can be planted where the old one used to be and the stump no longer forms an obstacle. The mobile stump cutter is highly maneuverable and can reach virtually any position.
