An apparatus to lower or raise landing gear on a trailer or semi-truck comprising a tool having a center body with a coupling device and a power coupling that is selectively engageable with a rotatable projection on the landing gear. The power coupling is operatively engaged with a worm gear within the center body and thereby with the coupling device. A powered drill is engaged with the power coupling and is actuated to rotate the power coupling in a first direction or in a second direction. The power coupling rotates the worm gear, which rotates the coupling device and thereby the projection on the landing gear. Rotation of the projection in one direction lowers the landing gear. Rotation of the projection in the opposite direction raises the landing gear. The user selects to raise or lower the landing gear simply by causing the drill chuck to rotate clockwise or counter-clockwise.
