Abstract
An apparatus for connecting an attachment to a vehicle includes first and second mounting pegs mounted to one of the attachment and vehicle, a mounting arm having first and second cut-outs sized and spaced to receive the respective first and second mounting pegs, and first and second latches that are pivotable to trap the mounting pegs in the cut-outs. The apparatus further includes a detent mechanism resiliently holding the first latch in each of the latched and unlatched positions with a detent force. An over-center biasing mechanism provides a biasing force along a line of force, and urges the second latch into the latched and unlatched positions in response to the line of force being on one side of the pivot axis or the other.
