ABSTRACT:
A parking lock for a vehicle such as a skid steer loader is designed to provide a positive lock of drive elements when certain conditions are present on the loader, such as the absence of an operator on an operator seat or the movement of an operator restraint to its non restraining position. The lock member comprises a disc on a final drive axle, that has a member that engages lugs on the disc to provide the locking function, and a friction brake manually operable to engage the discs to reduce the speed of rotation of the discs. The discs having lugs thereon formed in relation to the forces urging lock member toward the discs, such that the lock member will ride on the outer periphery of the disc until the speed has been reduced to a selected amount generally by operation of the brake.
