Abstract

The adaptor (18) for a tool head to an earth working vehicle boom has a quick change attachment (16) having claws (20) which selectively engage the flats of a locking pin of one end of the adaptor. The opposite end of the quick change attachment from the claws has a lug (30) to engage flats on the opposite adaptor locking pin. The quick change attachment can be mounted on either side of the adaptor using the respective flats. There can be locking pins (38,40) on either side of the adaptor, with respective flats.
