PROBLEM TO BE SOLVED: To smoothly facilitate mounting and demounting operation when mounting and demounting an implement from the side of the machine body at a low production cost by a simple and compact structure. SOLUTION: An apparatus for connecting an input shaft of the implement to a yoke joint 7 supported on an auto-hitch 5 is obtained by forming a main frame 9 of the auto-hitch 5 into a nearly inverted U-shape, securing an upper connecting body 11 for supporting the top mast of the implement in the topmost part thereof, securing lower connecting bodies 12 to both sides in the lower part and, on the other hand, supporting a holder 19 for holding the rear of the yoke joint 7 from both the left and the right sides with supporting bodies 21 secured to both sides in the lower part of the main frame 9. Inverted U-shaped supporting parts are formed on both the left and the right lateral parts of the holder 19 to support the supporting parts with the tips of the supporting bodies 21. Thereby, the rear of the yoke joint is composed so as to be freely oscillationally hung downward. A holder posture holding mechanism during connecting the implement is obtained by bringing straight-line parts of the supporting parts into contact with the tip lower parts of both the supporting bodies 21.
