PURPOSE:To shorten a mounting time and facilitate mounting while eliminating the need for a tool at the time of mounting by easily installing a backhoe to a tractor automatically. CONSTITUTION:A connecting section 14 composed of an upper opened shaped recessed section is set up on the tractor side, and a section to be connected 35 consisting of a round bar material fitted to the connecting section 14 from an upper section and coupled in an axial peripheral rotatable manner in the left and right direction is installed on the backhoe 7 side. On the other hand, a pair of mount holders 38 are mounted at the upper position of the section to be connected 35 on the backhoe side in an opening-closing-free manner while energizing springs 44 energizing the mount holders 38 under an open state are setup. When a backhoe is turned around the section to be connected 35 so as to be brought near to a tractor at the upper position of the section to be connected 35 on the tractor side, a mount bar 15, which is inserted into the mount holders 36, pushes the mount holders 38 and is coupled with the mount holders 38 by closing the mount holders against the energizing springs 44, is attached. A locking member 48, which is held between the mount holders 38 being interlocked with the closing operation of the mount holders and prevents the opening operation of the mount holders 38, is mounted. |
