It was difficult to hear the instructions given by, and an accident often occurred due to an erroneous operation due to a transmission error. In addition, when the wire rope for towing was slightly floated and stretched across the farm road so as not to scratch and damage the road surface, bicycles, motorcycles, etc. were caught on the wire rope, which was also a cause of traffic accidents.

Further, in the method of pulling and moving the work machine by the tractor, since the distance between the tractor and the work machine corresponds to the movement distance in one work of the work machine, the pulling area corresponding to the work area as a whole. Not only is necessary, but also two operators, a tractor driver and a work machine operator, are required, and various inconveniences such as transmission errors due to difficulty in listening due to voice operation instructions occur. There is.

The object of the present invention has been made in view of the above-mentioned drawbacks, and one worker can arbitrarily operate the work machine, and an accident due to a transmission error between a plurality of operators can be prevented. Another object of the present invention is to provide a towing and moving work machine which can be prevented and can work in a small work area.
