发明名称 Trailer mover
摘要 A trailer mover secured to the forwardly extending tongue of a recreational or multi-purpose trailer. The trailer mover includes a bracket pivotally attached to the trailer tongue and a gearbox rotatably attached to the bracket. The gearbox is pivotally movable between a lowered vertical working position and a raised horizontal storage position. Further, the gearbox is selectively rotatable with respect to the bracket to allow steering when in the working position. A rubber-tired groundwheel extends from the distal end of the gearbox and is powered by a hand crank, which drives a set of gears which provide a mechanical advantage.
