Abstract

The links of a tractor power lift mechanism have coupling hooks 8, 25, 26, and the lower links 3, 4 are connected by a U-shaped member 38 whose limbs 39, 40 are pivotal in a sleeve 41 to allow limited independent vertical movement of the links. The limbs 39, 40 can be locked in position by the device 45. The hooks 25, 26 are pivoted to the lower links through a silent block bush. Latches 33, 34 are associated with the hooks and are remotely operable. The upper link 5 is extensible with locking device 12.
