Patent attributes
A system, apparatus and method, for enhancing resolution during remotely controlled adjustment of a fore/aft trim angle of a frame of a towable tillage implement, utilize a fore/aft trim angle adjustment arrangement operatively attached between a hitch and the frame of the implement for tilting the frame at a desired trim angle along a fore/aft axis of the frame. An adjustable-length fore/aft trim linkage is operatively connected between the frame and the hitch for adjusting and maintaining the trim angle. A linear actuator is operatively attached to the trim angle linkage for remotely controlling the length of the trim angle adjustment linkage to thereby adjust the trim angle as a function of a stroke of the actuator. The fore/aft trim linkage provides an adjustment in its length that is proportionally less than the stroke of the actuator, to thereby provide enhanced resolution for remote control of the trim angle.
