<p>TREE SHEARER A shearing device is disclosed for severing trees and the like. The device is vehicle mounted, preferably on the front of a tractor, so that forward movement of the tractor causes shearing of a tree in contact with the device. The device includes a frame member with a pair of forwardly extending spaced arms one of which has a pivot member mounted thereon, with the pivot member carrying a severing or shear element that can be moved in an arc toward and away from the other arm of the frame member. A tree brought into contact with the severing element will be severed as the severing element is caused to move toward the other arm of the frame member due to continued forward movement of the vehicle. After a tree has been severed, the pivot member is preferably biased to automatically return to normal position near the end of the arms of the frame member with the severing element at least partially spanning the space between the arms. Each tree sheared falls rearwardly and to one side in substantially the same manner and direction.</p> |
