ABSTRACT:
A land clearing device that is sized and configured to be attached to a small earth moving machine, such as a skid loader. The land clearing device has a pusher assembly with telescopically extendable actuator arms that are operated by a control unit accessible from the interior of the earthmoving machine. When the actuator arms are extended, the forward end of the pusher assembly applies lateral force on a trunk of a tree, pushing the tree until uprooted. The pusher assembly is supported by a pair of upright legs that rest on the ground and provide stability to the pusher assembly, which cantilevered from the upright legs. A Y-shaped grabber assembly has a front hook that partially encircles and holds the tree below the location of contact with the pusher assembly. A mounting assembly is secured to the pusher assembly and the grabber assembly by a common securing rod about which the pusher assembly and the grabber assembly can pivot. The mounting assembly is configured for detachable mounting on a front of an earthmoving machine.
