ABSTRACT:
A leveling system designed for use with a vehicle having a reversing assembly including a table, an A-frame and a swivel member. The reversing assembly may be rotatably mounted to the vehicle with a lifting mechanism designed to elevate the reversing assembly for transportation when not in use. The leveling system is rotatably mounted to the A-frame and stabilized with parallel bars which function to achieve leveling of the assembly. Two chains of equal length are fixed to opposite ends of the leveling system, each at an equal distance outward from the center of the system and each connected at its other end to the lifting member of the vehicle. The chains aid in the lifting and leveling of the system.
