Louis Renault enlarged Renault's scope after 1918, producing agricultural and industrial machinery. The war from 1914-1918 led to many new products. The first Renault tractor, the Type GP was produced between 1919 and 1930. It was based on the FT tank. Renault struggled to compete with the increasingly popular small, affordable "people's cars," while problems with the United States stock market and the workforce slowed the company's growth. Renault also had to find a way to distribute its vehicles more efficiently. In 1920, Louis signed one of its first distribution contracts with Gustave Gueudet, an entrepreneur from Amiens, France which they still maintain a relationship.
