Abstract
A dual action leveling system for a disk or similar implement connected between the hitch and the lift wheel assembly includes a transport stop for providing a fixed hitch position for good transport leveling and stability. The system includes a fore-and-aft extending member with first and second coil springs and an adjustable spring abutment member threaded through one end of a rod for providing leveling for different ground conditions. Weight can be transferred to and from the front of the implement by simply turning a crank located at one end of the rod. For example, weight can be transferred to the front of the implement to provide compensation for added weight of a rear mounted attachment. The spring structure provides a self-compensating effect which resists changes in front-to-rear implement leveling with changes in ground conditions.
