An apparatus and method for controlling variation in the pitch of an agricultural vehicle, where the apparatus includes a controller that controls a position of an implement attached to the agricultural vehicle, and a first valve that is coupled to, and receives a first control signal from, the controller. The apparatus further includes a suspension cylinder having a first chamber that is hydraulically coupled to the first valve. The first control signal provided from the controller is functionally related to a first additional control signal provided by the controller, and the first additional control signal is used to determine the position of the implement.
