Abstract:
An agricultural implement including a frame having a pair of wings pivotally mounted thereon for pivotal movement between raised transport positions and lowered working positions, each said wing having a wing actuator connected thereto for effecting said pivotal movement of said wings, and a headlands control system including a headlands actuator connected to both of said wing actuators and being movable between first and second positions enabling operation in either of two modes such that:(A) when the headlands actuator is in the first position as during a ground working operation, said headlands actuator moving said wing actuators to a lower working position so that the wings are provided with sufficient downward range to enable the wings to be pivoted downward below horizontal as may be required during operation over uneven ground, and(B) when the headlands actuator is in the second position as when the implement is raised at the field headlands, said headlands actuator providing a higher working position for said wing actuators so that the downward range of pivotal motion of the implement wings is limited in such manner as to assist in preventing excess wing drooping and providing adequate wing-to-ground clearance as when turning the implement at the field headlands.
