Clarktor Aircraft Tugs in Britain and Australia

[Hanno Spoelstra]

From the Clark site:

1927
The Clarktor tow tractor is introduced. The Clarktor was used to pull airplanes and warehouse trailer trains. It was equipped with an electric self-starter, the first industrial truck or tractor to have this feature as standard equipment. The Clarktor remained in production until 1987.
