Abstract

A quick attachment carrier assembly (10) for releasably connecting an attachment (12) to a front end loader (14) comprises a pair of carriers (24) with top and bottom notches therein adapted to receive transverse pins (40, 42) on the implement. Pivotal hooks (46) are provided on the carriers (24) for engagement with the pins (42) for interconnecting the implement (12) to the loader (14). The latch hooks (46) are preferably secured together and controlled in common by means of a single lever (52) and plunger (56) which permit positive locking of both hooks in either the latched or unlatched positions.
