Abstract
A quick implement attachment mechanism (2) utilizes a single coupling unit having two receiving sides (18) interconnected by a longitudinal beam (20). Each receiving side of the mechanism will engage a pair of vertically aligned pins (12 and 14) mounted on each side of an implement (6). The bottom portion of each receiving side has a bottom U-shaped member (28) which engages the lower pin at the same time a top U-shaped member (26) proximate the upper portion of each receiving side engages the upper pin. A fold-up and fold-down dog 32 positively locks the upper pin within the upper U-shaped member, maintaining both the upper and lower pins within the U-shaped members of the quick attachment mechanism.
