Renault first began building automobiles in 1898 and had been experimenting with tractors by 1910. During World War One, Renault built a light tank for the French Army, and its first production tractor was based on this design. Tractors became a priority after World War Two, in part due to orders from the government to rebuild the farm economy. Renault Agriculture was acquired by Claas in 2004, when the Renault name was dropped.
