   In 1930 the 15/30, the first Marshall diesel tractor was introduced. Based on the Lanz Bulldog design it had a single cylinder two-stroke engine with a bore of 8 inches with a 10 inch stroke, maximum r. p. m. was 550. An improved version the 18/30 was made between 1932 and 1934. In 1935 the 12/20 was introduced.
