A tool mounting apparatus is disclosed for detachably mounting a tool component such as for example a bucket, on a carrier such as for example the dipper stick of a backhoe. A power hitch component is connected to the carrier. Notches on one of the components are arranged to receive a first engagement member(s) on the other component. A support surface on the power hitch component is arranged to engage a second engagement member(s) on the tool component. A power actuated locking member is mounted on the power hitch component for movement between an unlocked position permitting relative engagement and disengagement between the notches and first engagement member(s) as well as between the support surface and the second engagement member(s), and a locked position securing the second engagement member(s) relative to the support surface. The arrangement of the support surface relative to the locking member is such that the force exerted on the second engagement member(s) retains the first engagement member(s) in the aforesaid notches.
