ABSTRACT:
A snow ski tow bar adapts a prior art aircraft tow bar for attachment to a landing gear of an aircraft to which a snow ski has been attached. The snow ski tow bar modifies an existing tow bar with a second set of connectors that adapt the snow ski tow bar for connection to the landing gear of the aircraft having the snow ski. In addition, the existing wheels of the prior art tow bar are replaced with a second set of wheels that are spaced outwardly from the original wheels. This positions the second set of wheels on the snow ski tow bar where they are extended outside the lateral width of the snow ski on the landing gear. The second set of wheels support the tow bar in a position above the snow ski with the second set of tow bar connectors connected to the aircraft landing gear.
