タ。A rear lift arm 5 that is raised and lowered by a single-acting hydraulic cylinder 4 is installed at the rear of the fuselage, and a front lift arm 8 that is raised and lowered by a single-acting hydraulic cylinder 7 is equipped at the front of the fuselage, and a lever 9 is operated. In a tractor equipped with a mechanical position control mechanism that raises and lowers the rear lift arm 5 to a height corresponding to the position and automatically stops the rear lift arm 5, the position control valve 13 of the hydraulic cylinder 4 for raising and lowering the rear lift arm and the rear lift arm raising and lowering. The flow rate to the rear lift arm lifting hydraulic cylinder 4 is divided into a position control hydraulic circuit between the rear lift arm lifting arm 5 and the front lift arm 8 at a fixed ratio. A diverter valve 16 for lowering the rear lift arm 5 and a collecting valve 17 for lowering the rear lift arm 5 and the front lift arm 8 at a constant ratio are interposed.
A tractor characterized in that the position of the front lift arm 8 is controlled by diverted oil to the front lift arm 8.
