Abstract

PURPOSE:To provide the accuracy of plowing work, by setting the response speed of operation to the deviation of the detected plowing depth from the target value and the control of the depth in two modes, i.e. high-speed and low-speed, and switching the above modes according to the speed reduction ratio of a speed reducer of a tractor. CONSTITUTION:A lifting mechanism 19 is controlled by a low-speed control signal when a shift lever of a tractor A is shifted to the forward 1st position. When the shift lever of the tractor is shifted to the forward 2nd position or higher, the lifting mechanism 19 is controlled by a high-speed control signal. The lifting of a working machine B can be controlled at optimum operation speed to both running speeds corresponding to the 1st speed and the 2nd speed or higher, respectively.
