In 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.

John Deere Model D
Despite the severe farm economy depression, Deere management decided to build a final John Deere D prototype in 1923.

The first Model D rode on steel wheels with a 6.5x7.0 inch (later 6.75 x 7.0 inch) two-cylinder hand-cranked engine. It was not however the first tractor to bear the John 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 1918/19) had all carried the Deere name before the D.
