Abstract

PURPOSE:To reduce the time lag of the control of plowing depth, by correcting the extent of control operation for the control of plowing depth by a pitching sensor by the data detected by a height sensor and a speed sensor and carrying out the tilling work to flatten the furrow pan. CONSTITUTION:The surface unevenness of a field is detected with a height sensor 24 and the time to pass the front and rear wheels 8, 7 and a working machine B of a tractor A over the uneven surface of the field is detected by a speed sensor 25. The extent of control operation for the control of plowing depth by a pitching sensor 22 is corrected by the data detected by the above sensors. The variation of plowing depth caused by the lateral inclination of a tractor and the troubles of engine, etc., can be prevented and the time lag caused by feed-back control can be eliminated by this process.
