Abstract
A system, apparatus and method for adjusting fore/aft level trim of the frame of a towed agricultural tillage implement utilize an electronic control unit that receives an input signal indicative of a desired depth of penetration of tillage tools operatively attached to the front and rear of the implement frame, and automatically computes a desired for/aft trim angle as a function of the desired depth input, and then adjusts the fore/aft trim of the implement frame by titling the frame toward the front or rear of the frame in accordance with the desired fore/aft trim angle computed from the desired depth input signal.
