ABSTRACT:
Cable operated locking structure permitting an operator to lock and unlock the front of a loader without leaving the tractor seat. An eccentric cam and a cam operating wedge are secured on a front end assembly which also includes a mounting stand arrangement. A front mounting frame is connected to the tractor frame and includes a stop member which engages a guide member located on the assembly. The guide member and stop member secure the mast arm in the transverse and vertical directions, and the cam is movable into a cavity area on the front mounting frame to secure the mast arms in the downward and forward directions. Since the locking structure and parking stand are a single assembly, the loader can be offered either with or without the locking structure and parking stand features.
