The drawbar power increased to 38 horsepower (28 kilowatts), and a new six-speed transmission was also added. Deere & Company publicized the G as a three-plow tractor, and it was built until 1941, when the GM (G, modernized) replaced it. It was fitted with a 36 horsepower (27 kilowatts), 425 cubic inches (6.96 litres) engine, and a four-speed transmission. There were also eight different Model B tractor variations, the same as the larger Model A. This tractor had a shorter frame than the Model A, but it was eventually lengthened so it could use some of the same equipment that the larger models A and G used. The tricycle wheel design, patterned after that of the Farmall tractor, reduced steering effort, and greatly increased maneuverability. Some of these were tricycle, hi-crop, orchard, single front tire, and industrial models. There were eight different model A variations. The tractor was 25 horsepower (19 kilowatts), was 309 cubic inches (5.06 litres), and had a four-speed transmission. The John Deere Model A came off the assembly line in April 1934. These are commonly known as "GPO Lindemans". Some GPOs were fitted with crawler undercarriages from the Lindeman Brothers in Yakima, Washington. This tractor had specialized shielding for groves and orchards and around low-hanging branches. The John Deere general purpose orchard tractor, or "GPO", from April 1931 to April 1935.
JOHN DEERE 750 DOZER HORSEPOWER SERIES
The John Deere GP wide-tread Series P, a GPWT with narrowed rear tread width designed to suit potato rows, built between January and August 1930.The John Deere GP wide-tread, or GPWT, built from November 1929 to November 1933.The John Deere two-wheel tricycle-front GP, or GP-tricycle, of which twenty-three units were built between August 1928 and April 1929.The standard-front GP, or John Deere standard, built from March 1928 to February 1935.The John Deere Model GP was built in five distinct versions through the course of its production: In 1930, the GP was updated with a 25 horsepower (19 kilowatts), 339 cubic inches (5.56 litres) engine. This new model GP had the same horsepower, engine displacement, weight, and three-speed transmission as the model C. On June 20, 1928, the model designation was changed from "C" to "GP", to avoid confusion with the "D" when dealers were phoning in orders to the factory. In 1926, Deere & Company advertised the model as the "John Deere industrial tractor", with 40 in × 8 in (101.6 cm × 20.3 cm) rear wheels and 24 in × 3.5 in (61.0 cm × 8.9 cm) fronts with solid tires. The company replaced the 465 cu in (7.62 L) two-cylinder engine with a 501 cu in (8.21 L). Solid rubber tires were added, and engineers fitted a 28 tooth sprocket to the final drive, giving a road speed of 4 mph (6.4 km/h). Steel wheels were not suitable for hard surfaces, and the gearing was too slow for safe road speeds. It was not, however, the first tractor to bear the Deere name as a number of Deere experimental tractors, and the John Deere Dain all-wheel drive tractor (of which approximately 100 were produced during 19) had all carried the Deere name before the Model D.īy 1925, Deere & Company realized the standard Model D did not meet customers' needs for industrial applications. The first Model D rode on steel wheels with a 6.5 by 7 inches (16.5 by 17.8 centimetres) (later 6.75 by 7 inches (17.1 by 17.8 centimetres)) two-cylinder hand-cranked engine rated 15 to 27 horsepower (11 to 20 kilowatts).
The Deere Model D was produced from March 1, 1923, to July 3, 1953, the longest production span of all the two-cylinder John Deere tractors.
Frey (father of Ford Mustang designer Donald N. Although the Dain AWD was ahead of its time, with features such as a shift-on-the-fly transmission, Deere halted production in late 1919, partly because the cost of the Dain tractor was double that of the Waterloo Boy, and partly because of the death of Dain Sr.ĭespite a rather severe farm economy depression at the time, Deere & Company management decided to build the Model D prototype in 1923, designed by Muir L. By 1919 when that production run was complete, Deere had purchased the Waterloo Boy Company.
After several prototypes, the design was finalized in 1917, and 100 production units were ordered. The next year, Deere decided to design its own tractor, and Dain founder, Joseph Dain Sr., was directed to design that tractor. In 1911, Deere purchased the Dain Manufacturing Company of Ottumwa, Iowa. The Dain all-wheel drive was the first tractor produced by John Deere, and had only a single rear wheel.
