Abstract

PURPOSE:To carry out accurate and stable control of plowing depth, by attaching a speed sensor to a main body of tractor, determining the delay time between a non-contact sensor and the center of a rotary and delaying the control of plowing depth by the delay time. CONSTITUTION:A non-contact sensor 12 is positioned in front of a working machine R and an angle sensor 14 is attached to the pivoting part of a case support at the rear end of a hitch. A plowing depth setting dial 17 and a vehicle speed sensor 19 are connected to a control circuit 13 and the delay time t (=l/speed of vehicle) between the non-contact sensor 12 and the center 0 of a rotary is calculated. The control of plowing depth is started after the lapse of the period corresponding to the delay time.
