Abstract
A lightweight hand-operated aircraft tug for small aircraft includes a main frame upon which a drive drum is movably mounted for engagement with the wheel of an aircraft. A reversible pawl and rachet or an equivalent device controls the direction of rotation of the drum. A lever arm controls the engagement and disengagement of the drum with the aircraft wheel. A pair of axle-engaging inserts are associated with the main frame of the tug so as to be engageable with the axle of the aircraft when the drum is driven into engagement with the wheel by the operation of the lever arm.
