Abstract
A loader having a vehicle frame, a load lifter, a pair of arms each having one end pivoted to the frame and the other ends pivoted to the load lifter, at least one tilt cylinder carried by the arms and having an extendable rod, first links pivoted intermediate their ends to respective arms and at their ends to the rods and to second links. The second links are pivoted to the load lifter and there is included a hydraulic system including a manual actuator for controlling the cylinder to pivot the load lifter between forward and rearward positions on the arms. The invention contemplates a hydraulic element for sensing the position of the load lifter and for halting the flow of hydraulic fluid to and from the cylinder when the load lifter is moving forwardly on the arms just short of the forward position to halt such movement and provide a hydraulic cushioning effect.
