Description of the Related Art A mowing position sensor for detecting a mowing position, which is the height of a mowing device with respect to a vehicle body, is provided with a pivot shaft center for vertically supporting a mowing frame with respect to the vehicle body. Ideally, it should be installed on the top or on the pivot axis of the mowing suspension arm that is connected to the body of the mowing frame in a freely expandable and contractible manner, but it is difficult to install it on such a pivot axis. There are many configurations that interlock with the sensor arm of the mowing position sensor from the mowing frame, the mowing suspension arm, etc. through the link mechanism, so there are many detection errors of the mowing position sensor due to the link mechanism,
The configuration also becomes complicated.
