Abstract
A quick coupler provides a way to securely lock implements to the coupler utilizing a design which receives hooks at connection locations and then directs pins into pockets at a rear of the implement. Instead of directing the pins along a pocket axis (as is done in the prior art), the pins are directed at an angle relative to the pocket axis thereby securely connecting the coupler to the implement. In fact some embodiments can have a pin extension system spaced from a wedge plate surface defining the pocket of the implement.
