Abstract
A quick coupling and release mechanism for attaching a material handling bucket, blade, compactor, impact hammer, or other attachment to the free end of a scoop arm extending from a loader or backhoe. The quick coupler has a three-leg configuration, including a hub, a pair of spaced apart depending legs adapted to be pivotally connected to the end of a loader arm, and a third leg extending from the hub in a cantilevered fashion with a slotted end for selective engagement with a permanent mounting pin on the bucket. The conventional push-pull links operatively connected with the loader arm are pivotally connected at one end to the third leg of the quick coupler, and the hub of the quick coupler is attached to the bucket by a releasable bucket mounting pin, thereby completing the coupled connection between the bucket and loader scoop arm. A single operator can easily handle the entire coupling or uncoupling operation without special tools. Further, the quick coupler does not require a special bucket construction or the attachment of special parts to the bucket for its operability.
