A quick coupling device for quickly and easily coupling and decoupling a work implement to and from a stick assembly is disclosed. The quick coupling device includes a hook member defined in the stick assembly. The hook member defines a recess. An implement pin secured to the work implement is positionable within the recess. The quick coupling device further includes an over-center spring which biases or otherwise secures the implement pin within the recess. The quick coupling device yet further includes an actuator which selectively loads the over-center spring so as to secure the implement pin within the recess, or alternatively removes the load from the over-center spring so as to allow the bucket to be decoupled from the stick assembly. In one embodiment the actuator includes a operator controlled fluid cylinder, whereas in another embodiment the actuator includes a lever assembly having a lever with a cam lobe secured thereto. |
