Abstract
An implement frame (12) is supported by two pairs of laterally spaced wheels (36, 37 and 38, 39) whose vertical position relative to the frame is controlled by a pair of parallel master cylinders (61, 62) connected to one pair of wheels (36, 37) and a pair of parallel connected slave cylinders (63, 64) connected to the second pair of wheels (38, 39). The master and slave cylinders are series connected to provide even raising and lowering of the implement frame. The parallel connections between corresponding ends of the master and slave cylinders (61, 62, 63, 64) provide a walking beam effect with resulting equal loading on the wheels (36, 37, 38, 39).
