WORK VEHICLE, METHOD FOR OPERATING TOW APPARATUS, AND METHOD FOR ASSEMBLING TOW APPARATUS

A tow pin (6) has a main body portion (6a) in a columnar shape and a first protrusion (6b) protruding outward from an outer circumferential surface of the main body portion (6a). An upper bracket structure (2, 4) has a first through hole (8a) in which the main body portion (6a) is inserted and restricts passage of the first protrusion (6b). A lower bracket (3) is located under the upper bracket structure (2, 4) at a distance from the upper bracket structure (2, 4) and has a second through hole (3a) in which the tow pin (6) can be inserted. The main body portion of the tow pin (6) is inserted in at least the first through hole (8a) and the first protrusion (6b) is located under the upper bracket structure (2,4).
