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. Model D (Spoker Model D) John Deere Model D tractorĭespite 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. In March 1918, Deere & Company decided to continue its foray into the tractor business by purchasing the Waterloo Gasoline Engine Company which manufactured the popular Waterloo Boy tractor at its facilities in Waterloo, Iowa.ĭeere & Company continued to sell tractors under the Waterloo Boy name until 1923. It was made by thresher-man John Froelich. The predecessor of the Waterloo Boy came about in 1892.

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. 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.
