<p>A coupling for coupling together a tractor and an agricultural implement to be towed/lifted by the tractor has two mating parts 14, 16 one of which 14 is mounted on the tractor and the other of which 16 is mounted on the implement. The two parts fit one inside the other and fixed pins 30 then locate the two parts together. After the parts have been fitted together, movable pins 32 are positioned to lock the two parts so that a secure coupling between the tractor and the implement is formed. The parts can be fitted together by driving the tractor with the part 14 up to the implement with the part 16 whereupon one part engages within the other. <IMAGE></p> |
