A coupling assembly (10) for coupling a towed implement to a prime mover comprises a manifold (12) which can be mounted to the prime mover, and a coupler frame (16) which can be mounted to the implement. A pivot pin (42) projects laterally from a side of the manifold (12). A lever member (44) is pivotally mounted on the pivot pin (42). The lever member (44) has a hub (46) which rotatably receives the pivot pin (42), a first arm (48) projecting away from the hub (46), a second arm (50) projecting away from the hub (46), a latch pin (52) projecting laterally away from the first arm (48), and a locking recess (58) formed by the second arm (50). A lock pin (71) projects laterally and is supported by the coupler frame (16). A latch member (60) is fixed to the coupler frame (16). The latch member (60) has a body (62), a latch finger (64) spaced apart from the body (62), and a spacer (66) connecting the latch finger (64) to the body (62). The body (62), the latch finger (64) and the spacer (66) form a slot (68) therebetween. The body (62) forms a slot wall (70) which is spaced apart from the latch finger (64) and which faces the latch finger (64). The body (62) also forms a latch wall (72) which is joined to the slot wall (70). The latch wall (72) engages the latch pin (52), pivots the lever member (44) and moves the latch pin (52) into the slot (68) as the coupler frame (16) moves towards the manifold (12). The second arm (50) moves to a locking position wherein the locking recess (58) receives the lock pin (71) as the lever member (44) is pivoted by the latch member (60). |
