Summary

Illustrated sales catalogue describing two All-British built Fowler crawler tractor designs:

The "Three-Thirty" - a lightweight mobile unit suitable for agricultural work, aerodrome and road construction with graders, etc., powered by a 3-cylinder Fowler-Sanders compression ignition heavy oil engine operating at 1,100 r.p.m.

The "Forty-Four" - a heavier unit particularly suited to the rough and tumble of tasks such as timber-logging, earthing-moving with scoops and bulldozers and heavier agricultural work, powered by a 4-cylinder Fowler-Sanders compression ignition heavy oil engine operating at 1,100 r.p.m.

The firm John Fowler & Co, had its origins as a steam ploughing equipment manufacturer in the early 1850s. Although the business initially concentrated on the marketing of steam ploughing engines and ploughing tackle designed and patented by John Folwer but manufactured by other firms, it established its own Steam Plough Works at Hunslet, Leeds, in 1862. Subsequently the firm developed into one of the leading British manufactures of steam traction engines, steam rollers and smaller industrial steam locomotives. The firm began experimental development of internal combustion engine powered machinery in 1902, however, it was not until after the First World War that it seriously attempted to enter the field. It's first crawler-mounted petrol-engine powered tractor the 'Gyrotiller' was introduced in 1927. The first diesel-engine powered Fowler crawler tractor was introduced in 1933. Arthur Freeman Sanders was appointed by Fowlers to head the firm's design engine design department in 1934, and the "Fowler-Sanders" trademark was registered in 1936, following the successful adoption of several important improvements in diesel engine design jointly patented by Sanders and Fowlers.
