<p>A hitch assembly (10) for automatically coupling a tractor's towing linkage to an implement is formed from opposed substantially identical frames (11 and 15) provided with pairs of respective complementary spigot and socket connectors (26 and 31) which engage to locate the frames (11 and 15) in a joined relationship. Releasable locking means (32 and 45) are provided for locking the frames together. The frames (11 and 15) are also provided with coupling means (12 and 14a) so that one frame (11) can be coupled to the towing linkage and the other frame (15) can be coupled to the towing linkage connections on the implement. The hitch assembly may also include complementary drive transfer assemblies supported on each frame (11 and 15). The drive transfer assembly on the first frame (11) is connectible to the drive shaft of a prime mover and the drive transfer assembly on the second frame (15) is connectible to the driven shaft of an implement and wherein the drive transfer assemblies couple to transmit drive from the drive shaft to the driven shaft when the frames (11 and 15) cooperate to secure the implement to the prime mover.</p> |
