A quick coupler includes a coupler body having a recess, a driver, and a pusher movable between a first position and a second position. A latch is movable between a latched position in which the latch restrains a coupling pin of a work tool in the recess when the coupling pin is located in the recess and an unlatched position in which the latch allows the coupling pin to be released from the recess. The driver drives the pusher to move to the second position, and the pusher drives the latch to move to the latched position when the pusher moves to the second position.
