The companies poor sales caused a collapse and the firm was bought by Tractors (London) Ltd who built the Trusty tractor. The Rushton tractor was built in small numbers into the 1930's. At the "World Trials" in Oxford in 1930, both Fordson and the Rushton tractors were tested, but the Fordson failed to complete the tests due to a cracked block. The Rushton recorded 23.9 hp and the Fordson 20.8 hp. A petrol version was offered with Roadless halftracks fitted.
