Abstract

An excavator quick hitch (10) comprises a quick hitch body (12), the body comprising: a first mounting position arrangement (14) for attaching an excavator attachment (18) in a first position; and a second mounting position arrangement (16) for attaching the, or an alternate, excavator attachment in a second position. The quick hitch can facilitate mounting of more than one excavator attachment, at the same time.
