ABSTRACT:
A linkage system for automatically maintaining the orientation of a bucket of a tractor loader while the lift arms are moved between raised and lowered positions is disclosed herein. Several specific embodiments are illustrated and described in detail. Each embodiment incorporates one or more links joined to the lift arms in such a manner that a portion of that linkage is maintained generally parallel to the bucket end of the lift arm. By maintaining this parallel relationship throughout the rotation of the lift arm, the bucket positioning mechanism is displaced in such a manner as to counteract the rotation of the bucket induced by the motion of the lift arms alone. The automatic self-leveling feature improves the overall productivity of the tractor loader.
