ABSTRACT:
A quick attachment device for a tractor which has lift arms for supporting an implement, such as a loader bucket, lift fork, or the like. The rear side of the implement has two spaced-apart attaching portions in the form of hooks faced toward each other, and an attachment plate is held by the tractor lift arms and the lower edge is first positioned into the lower implement hook and then the plate is slid upwardly until the upper edge is engaged in the implement upper hook. A spring-loaded pin then automatically falls into a hole in the implement to secure the plate relative to the implement and thus attach the implement and plate together. A release cam is attached to the pin for withdrawing the pin and the attachment plate can then be manuevered out of the implement hooks to be removed from the implement when release is desired.
