![]() 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.

Thanks to Digitup for sharing the relevent pages from his guide with us so we can determine what year a given machine is.This section does not cite any sources. I'm making the reasonable presumption that the last serial number for any given year is one less than the starting serial number for the successive year. The guide as such only lists the beginning serial number for each year. ![]() The source of the data is from a farm equipment quick reference guide that's intended to assist dealers in determining the year and current market value of trade-in equipment. The serial numbers for the JD750B and JD750C cover all the variations (LT, WT, LGP). The list also shows a different set of serial numbers for the straight JD750 LGP (Low Ground Pressure) from the regular straight JD750. Odd that the list goes no further than 1995 when it lists the JD750C as being produced from 1995 thru 1999. Note: We have an overlap in serial numbers between the JD750 and JD750B in 1985 and 86. Note: There's a serial number jump here which appears to have occured across the line in 1983-4. Serial number list, by year, for the JD750 through JD750C.
