Claims

[Scope of utility model registration request]

A rotary switch that operates according to the relative positional relationship of a lift arm and a lift lever for instructing the height position of the lift arm to which the work equipment should be connected so that it can be raised and lowered, and a sensor that detects the height position of the work equipment. The lift arm is characterized by a configuration in which the rotation of the lift arm is controlled based on the operating status of the rotary switch in the case of manual control, or based on the detection result of the sensor in the case of automatic control. Work vehicle.
