Claim 11:
12. An apparatus for manual and powered operation of a jack mechanism of a landing gear for a semi-trailer, comprising:
a cylindrical shaft having a first end configured for coupling with a distal end of an operating rod of the jack mechanism of the landing gear of the semi-trailer;
a drive connection having a ratchet drive head at a first end and a shank at a second end, the ratchet drive head adapted to be removably received in and rotationally drive a second end of the cylindrical shaft, and a recess defined at a distal end of the drive connection;
a quick disconnect coupler connected with an end of a manual crank arm of the jack mechanism, the quick disconnect coupler adapted for releasable coupling with the recess at the distal end of the shank;
an idler sleeve surrounding the cylindrical shaft for rotation of the cylindrical shaft within the idler sleeve; and
a lug extending radially outwardly from the idler sleeve, a recess defined at a distal end of the lug adapted to removably couple with the quick disconnect of the manual crank arm.
