Steam engines Marshall's produced large numbers of steam
traction engines,
steam rollers,
portable engines and
agricultural machinery of all types. Among British manufactures, Marshall were second only to
Aveling and Porter in terms of the number of steam rollers they produced. In 1923 the company started selling tandem rollers.
Tractors In 1900 they started designing
internal combustion-engined tractors to be called the
Colonials, with a power of 16 to 32
hp (not comparable to modern hp) for the export market to replace steam engines, selling 300+ by 1914. In 1928 they started to develop a tractor similar to the
Lanz Bulldog from Germany. They launched the 15/30 (Model E) in 1930, followed by the 12/20 which became the Model M in 1938; this then developed into the
Field-Marshall in 1944. Production of the Field Marshall continued until 1957. A small number of MP4 and MP 6 tractors were produced after the Field Marshall, but tractor production effectively ceased until 1982, when Charles Nickerson bought the production rights to the
Leyland tractors range, producing them at Gainsborough (although using engines and parts from Leyland) and selling them under the Marshall name. Initially successful, the venture failed to generate enough capital to fund the successful development of new models and the company began to lose its market share. Models included the 502, 602, 604, 702, 704, 802, 804 and 904XL, which were a continuation of the corresponding Leyland models. Other new models were in 1985 the 100 (Leyland 6/98 engine) and a single 115 (Turbo 100 version). Tractor production moved to Scunthorpe under the ownership of Bentall Simplex. The swap to Perkins 4.236 engines from Leyland 4/98 engines resulted in the 752 and 852 (2WD), 754 and 854 (4WD), and 954XL (95hp 4WD), the six-cylindered 100-4 and 125-4 topped the range. Compact tractors in 1987 were the 184 (187hp 4WD) and 264 (26hp 4WD) and in 1989 were added the 224 (4WD 3-cylinder 22hp) and 304 (4WD 4-cylinder 30hp), all of which were made by Ferrari (tractors) of Luzzara. Around 1990 they began importing
Steyr tractors from Austria, and selling them as Marshall D642, D644, D742, D744, D842, D844, D944, D110, D135, and D150. This continued until 1992.
Aircraft In 1917 the company started to build aircraft at a new works built for the purpose on Lea Road in Gainsborough. The works became known as the Carr House works and the company built 150
Bristol F2B two-seat biplane fighters. When the aircraft were completed they were dismantled and towed to West Common in Lincoln to be flown, although some were flown from Layne's Field in Gainsborough.
Tracked Tractors and Bulldozers After the merger with Fowler, their experience with tracked agricultural and military vehicles was used to create the Fowler Marshall Diesel Crawler, which was launched in 1948. Fowler continued to develop and market tracked vehicles while Marshall produced the wheeled
Field Marshall tractors as well as other vehicles such as diesel road rollers. The tracked vehicles included the Fowler Challenger and from 1955 the
Track Marshall. The Track Marshall was a product that continued under various ownerships, with production of the final model, the TM200, continuing until 1998.
Diesel Road Rollers Marshall made diesel road rollers from 1930 until the takeover by British Leyland, latterly under the Road Marshall brand. ==Preserved examples==
