Abstract
An arrangement for controlling a hydraulic three-point hitch includes a hydraulic cylinder, first and second seat valves, and first and second pressure compensation valves. The hydraulic cylinder includes a working chamber, by which pressurized hydraulic fluid changes a lifting position of a lower arm of the hydraulic three-point hitch. The first and second seat valves are in fluid communication with the working chamber. The first seat valve selectively produces a flow connection to a high-pressure source. The second seat valve selectively produces a return connection to a hydraulic reservoir. The first pressure compensation valve is connected upstream of the first seat valve in a first through-flow direction. The second pressure compensation valve is connected upstream of the second seat valve in a second through-flow direction.
