PROBLEM TO BE SOLVED: To improve an operability of an autolift controller which is loaded on a tractor, etc., and linked to a turn state to lift an implement. SOLUTION: The tractor is equipped with a lifting and lowering switch to lift and lower the implement between a set upper position and a set lower position. The tractor is also provided with an autolift controller for detecting the turn operation and lifting the implement. In the case of loading both the apparatuses on the tractor, the upper positions of the implement are made equal and an operating feeling in lowering is made constant. A lifting speed is equalized to improve operability.
