Abstract
A system for ensuring the uniform height of gauge wheels for a towed implement assembly such as a seeder. The seeder has a frame structure with a series of front gauge wheels suspended by the front of the frame structure. A greater number of rear wheels are suspended by the frame structure to the rear of the front gauge wheel. A tow hitch is pivotally connected from the front of the frame structure for coupling to a work vehicle. A front bar having a first end and a second end is coupled to the tow hitch. A center actuator such as a hydraulic cylinder is coupled to one end of the front bar. A rear bar is placed in contact with the opposite end of the hydraulic cylinder. The front gauge wheels are raised by extending the cylinder and causing force to be applied to the front and rear bars. In this manner, the weight on the front wheels is distributed to the work vehicle via the tow hitch and the rear wheels.
