Abstract
A remotely positionable stabilizer wheel arrangement for a towable agricultural implement utilizes a control unit that receives an input signal indicative of a desired position of the stabilizer wheel, and/or a desired depth of penetration of tillage tools operatively attached to the front and rear of the implement frame, to automatically control a hydraulic positioning cylinder of the remotely positionable stabilizer wheel arrangement to position and hold the stabilizer wheel at the desired position of the stabilizer wheel, by simultaneously controlling pressure in both the rod and base ends of the bore of the hydraulic cylinder to hold the stabilizer wheel at a target position determined from the desired position input signal.
