The locking mechanism has a follow er member, a first hooked portion adapted to engage the reverse ratchet, and a second hooked portion adapted to engage the forward ratchet. The follower member is selectively controlled to force the first hooked portion into engagement wit h the reverse ratchet or the second hooked portion into engagement with the forwar d ratchet.
