ABSTRACT:
An agricultural implement frame supported on rockshaft mounted tires and having a rigidly mounted tongue employs a hydraulic leveler arrangement to maintain the level or pitch of the frame in the raised transport position and the lowered ground working position of the frame. The leveler arrangement includes a hitch bell crank pivotally connected to the frame lift mechanism. A hitch member is pivotally connected to the hitch bell crank. The bell crank is in the form of an adjustable truss and includes a pair of lift arms and a pair of triangular hitch arms the ends of which are connected by a turnbuckle. By adjusting the length of the turnbuckle, the pitch of the frame is made adjustable. The force of the lift cylinder to lift the frame is transferred about the hitch member to the front end of the frame to lift same as the rest of the frame is lifted. The arrangement operates in the reverse direction as the frame is lowered.
