PURPOSE:To enable simplifying of connection and separation of a work machinery, by a method wherein two U-shaped nipping means are positioned at a distance being wider than a width of a gear case, and after the attaching member of the work machinery engages the nipping means, a pin engages a pin hole. CONSTITUTION:A coupling device A has two brackets 1 located at a distance, and the two brackets are connected together by a frame 2 in which an approximately C-recess 2a is formed. A U-shaped nipping means 5 opening downward is attached to the lower part of each bracket 1, and pin holes 5a are provided in both sides of the opening part of the nipping means 5. The coupling device A is connected to a tractor C by means of an upper link 26, connected to a mast 3 at a projecting part 2b on the frame 2, and a lower link 27 connected to the bracket 1. In case a work machinery B, such as agricultural machinery, is coupled, tubular base frames 15 and 15' of a gear case 14 engage the nipping means 5, and after a strap metal 23 is placed, a coupling is made through engagement of a pin 24 with the pin holes 5a. |
