Abstract

An agricultural implement includes a frame having a pair of tool-carrying wings pivotally mounted thereon for pivotal movement between raised transport positions and lowered ground-working positions. Each wing has a hydraulic wing actuator connected thereto which is extendable and retractible for effecting the pivotal motion. A hydraulic wing actuator circuit is connected to each of the wing actuators, which circuit, when connected to a tractor hydraulic system, enables the wing actuators to apply down pressure to said wings when the wings are in the lowered working positions. A hydraulic pressure control valve system controls the down pressure exerted by the wing actuators.
