ABSTRACT:
When a tree stump has been split into several parts by a chopping action, the invention provides a gripping, shaking and cutting unit rigidly connected to the end of a vehicle-carried rotatable crane boom, having an adjustable effective length, for pulling out the stump parts along with their roots one by one from the earth in a direction substantially corresponding to the extension of the roots, and then shaking and cutting the stump parts.
