降制御装置。 A ground work machine 5 is connected to the rear part of the power agricultural machine 1 via a lifting device such as a three-point linkage mechanism 4 so as to be able to rise and fall freely, and on a cover 8 of the ground work machine 5,
A plowing depth detector 10 is provided to detect the plowing depth, and feedback control is performed so that the value set by a plowing depth setting device 13 provided near the cockpit 12 and the value detected by the plowing depth detector 10 are approximately equal. In the hydraulic lifting control device for power agricultural machinery, the rate of change per unit time of the detected value by the detector 10 is determined by the sensitivity selection S.
A hydraulic lift control device for a power agricultural machine configured to change the amount of feedback so as to be approximately equal to the rate of change in a certain specific sensitivity selected by W24.
