摘要
The auto hitch quick-release type hook end disclosed, designed for use with a 3-point linkage, features a dual safety lock system protecting against accidental unhitching. The hook (1) is of a general type having a safety catch (4) that juts over the seat (2) which accommodates the link ball of a hitched implement and thus locks the link ball into the hook, and comprises a ratchet-type mechanism incorporating two contoured yokes (8, 9) operating together in such a way as to prevent unwarranted rotation of the catch, hence accidental unhitching of the implement. The implement is freed by working a latch (7), an initial movement of which shifts and releases the ratchet mechanism, whereupon the safety catch is engaged and rotated in such a way as to allow of detaching the implement.
