ABSTRACT:
The invention comprises a hook attachment having a frame with a plurality of hooks pivotally mounted to the frame. The attachment has a engaging flange and eyelets for receiving the attaching flange and engaging pins, respectively on the front of the arms of a front end loader. The attachment has an attaching flange and engaging pins mounted on the front of the frame of the attachment for engaging an attaching flange and eyelets on the rear of a bucket, whereby the hook attachment may be attached directly to the front of a front end loader and used alone with the front end loader, or the attaching flange and engaging pins on the front of the frame of the locking attachment may engage the attaching flange and eyelets on the rear of the bucket to attach the bucket to the flange of the hook attachment so that the hook attachment and bucket may be used together on the front end loader.
