Abstract
A tillage implement includes an implement frame having a first lengthwise frame member, a second lengthwise frame member, and a lateral frame member connected to and extending between the first and second lengthwise frame members. A hitch assembly is rotatably connected to the implement frame. A wheel assembly is connected to the implement frame and moveable between a raised position and a lowered position. A rockshaft is rotatably connected to the implement frame and connected to the wheel assembly. A leveling assembly is connected to the implement frame, the rockshaft, and the hitch assembly. The leveling assembly is configured to adjust the position of the hitch assembly based on movement of the rockshaft. The leveling assembly includes an actuator connected to and aligned with a leveling link.
