The Issoise TU1 Tractor was a French design from 1939. It could tow and carry more than one ton of ammunition but never got any further than prototype stage. During tests it was found dangerously unstable. The tractor could easily topple over in hilly terrain due to its small wheel base.
The prototype of the tractor is on display at the Musée des Blindes in Saumur, France.
