Abstract
A tractor front hitch 10 is provided for mounting an implement on the front of a tractor. The hitch has socket 13 mounted for pivotal movement relative to the tractor, a pair of lower implement support links 12 which form a sub-assembly received in the socket 13, and one or more upper implement support links 14 supported from the tractor. The lower link sub-assembly 12 is moveable relative to the socket 13 between a coupling position, in which the lower link sub-assembly is at least partly withdrawable from the socket to facilitate coupling of the implement to the lower links, and a locked implement operative position in which the lower link sub-assembly 12 is locked in the socket 13. The lower link sub-assembly 12 may be moved fore and aft, and side to side relative to the socket 13 and is also rotatable in the general plane of the socket to facilitate coupling when in the coupling position.
