Abstract

A quick coupler (126) for holding an implement (104) is disclosed. The quick coupler (126) includes a frame (114) having a first plate (140) and a second plate (142). The quick coupler (126) includes a locking system (160) adapted to lock the implement (104) in the first plate (140) and the second plate (142). The locking system (160) includes a securing latch member and a hydraulic actuator (166) is operatively connected to the securing latch member. The securing latch member is configured to move along a guide provided in each of the first plate (140) and the second plate (142). The locking system (160) further includes a set of grooves (187) provided on at least one of the securing latch member and the guide. The set of grooves (187) are adapted to lock the securing latch member in a latched position.
