Claim:
A landing gear assembly for supporting a trailer, the landing gear assembly comprising: a housing; a means for connecting the housing to a trailer; a leg extension mounted on the housing for movement between an extended position and a retracted position of the leg extension relative to the housing, the leg extension having an externally threaded screw that is rotated to cause the movement of the leg extension; a gear mechanism operatively connected to the leg extension screw to cause the leg extension to move between the extended and retracted positions in response to operation of the gear mechanism and rotation of the leg extension screw; an input shaft mounted for rotation on the housing, the input shaft having a first end outside the housing that is adapted to be operatively connected to a hand crank and a second end outside the housing that is adapted to be operatively connected to a second gear mechanism of a second housing; an input gear mounted on the input shaft; an idler shaft mounted on the housing; and, an idler gear mounted for rotation on the idler shaft, the idler gear being operatively connected between the input gear and the gear mechanism to cause operation of the gear mechanism in response to rotation of the input shaft, and the leg extension screw, the input shaft, and the idler shaft all being positioned in a single vertical plane inside the housing.
