  • Patent number: 8544946
    Abstract: The tree and post remover is a removably attachable accessory for an operating vehicle, such as a skid-steer machine, tractor, or similar working machine having hydraulic power output. The tree and post remover has a mounting plate having a fixed jaw assembly extending therefrom and a movable jaw assembly captured and sliding laterally within the fixed jaw assembly. A hydraulic strut resides within the movable jaw assembly, and has one end attached to the movable jaw assembly and its opposite end attached to the fixed jaw assembly. Actuation of the hydraulic strut drives the movable jaw assembly toward or away from the fixed jaw assembly to close or open the jaws relative to one another. Each jaw assembly preferably includes a plurality of individual jaw members, opposite jaw members meshing with one another to allow the jaws to close upon objects of relatively small diameter.
