摘要:
An agricultural tillage implement including a main frame section having a pull hitch tube extending in a travel direction and a plurality of pivotally coupled wing sections coupled with the main frame section. Each of the plurality of wing sections has at least one pivotal sub-frame. A hydraulic actuator is connected between the wing frame and the sub-frame to urge the sub-frame between an operating position and an elevated transport position. An actuator controller is configured to apply a predetermined force of the sub-frame towards the ground independently of other sub-frames so as to provide a more uniform tillage of the ground.
