Roadless Ploughmaster – the four-wheel-drive conversions from Hounslow on a Ford basis, Ploughmaster 65 to 90, four- and six-cylinder Ford diesels, 57 to 58 kW
Roadless Traction of Hounslow, near London, specialised in converting standard tractors to four-wheel drive and, for the Ploughmaster range, fitted its own driven front axle to Ford chassis and engines. The number in the type designation gives the power class in hp – the Ploughmaster 65, based on the Ford 5000, with about 65 hp, the Ploughmaster 90 with a six-cylinder of about 90 hp – 6/4 denoting an earlier version with six forward and four reverse gears; the conversions kept the standard tractor's engine, gearbox and cab and added Roadless's own four-wheel-drive technology.

The register lists here 5 versions with 57 to 58 kW (65 to 78 hp) from four- to six-cylinder Ford diesel engines.
With its four-wheel-drive conversion, Roadless served a niche between the standard two-wheel drive of Ford tractors and the competition's factory four-wheel-drive models, above all for work on heavy or sloping grassland in Britain and Ireland. Forestry operations and municipalities also used the Ploughmaster for its improved traction on loose or wet ground.
On these conversions, the condition of the Roadless front-axle gearbox and drive shafts counts, engine condition of the Ford unit, clutch and gearbox, and rust on the bodywork; spare parts for the four-wheel-drive conversion are only available through specialists in British classic tractors.
