Scammell Contractor

The Scammell Contractor was a heavy 6x4 tractor unit that Scammell designed and put into production in 1964, when the company was part of the Leyland group. It was fitted with a Cummins 335 engine, a Lipe clutch and a Fuller semi-automatic gearbox, and could be ordered with Leyland 24 tonne or Scammell 30 and 40 tonne bogies. It was popular in the United Kingdom for operations above 240 tons gross train weight and was also used by militaries for tank transport. The Australian Army ran Contractors with 335 horsepower Cummins diesel engines and pneumocyclic gearboxes, as tank transporters in Vietnam War era trials and for heavy haulage of engineering plant for the Royal Australian Engineers. One trials vehicle carried the Scammell name, while most later units were branded Leyland. A Contractor Mk2 was developed in the late 1970s.
