ロール装置ｔ。A draft sensor connected to the top link detects changes in the compressive force transmitted from the work equipment side to the top link, and feeds it back to the hydraulic control valve to automatically adjust the vertical movement of the work equipment. While the draft sensor is constituted by a hydraulic cylinder, a master cylinder is provided on the spool driving side of the hydraulic control valve, and the piston rod of the master cylinder is connected to the spool driving side connected to the base end side of the hydraulic operating lever. It is pivotally connected to the plate, and the cylindrical portions of the two cylinders are communicated and connected by a pipe body filled with oil, so that changes in expansion and contraction of the draft sensor are transmitted to the master cylinder via the oil to switch and operate the hydraulic control valve. A draft control device for a tractor, characterized in that:
