Abstract:

A locking mechanism adapted for use with a lift arm assembly. The lift arm assembly is connected to and operatively associated with a lift actuator for movement between raised and lowered positions. The lift actuator having a tubular body and an extendable rod. The locking mechanism includes a lockbar having a proximal end and a distal end opposite to the proximal end. The proximal end is configured to be pivotally connected to the lift arm assembly and movable between an inoperative position and an operative position to selectively prevent retraction of the rod within the tubular body of the lift actuator. The locking mechanism further includes a release lever pivotally connected at the distal end of the lockbar and is adapted to move between a rest position and a working position.
