The 820 and 830 were similar overall, but also differed in their sheet metal exteriors, fuel tank designs, and color schemes. The 820, a larger version of the 720 and the 720, was basically the same as the 70, except for the model number, and that the sides of the hood are painted John Deere yellow. The 720 was upgraded to the 730 for 1959. The 730 featured more contoured bodywork than the 720, and came with more ergonomic features for the operator. Although the 730 had a short production run, it became one of Deere & Company's most popular models. The 730 also featured power steering and 24-volt electric starter motor, instead of the V4 pony starter engine. The 730 was available in diesel, gasoline, and LPG, as well as in row crop tricycle, row crop wide front, standard tread, and hi crop wide front formats. The 730 is very popular with tractor pulling enthusiasts, because of its weight, power, and slow speed. The 730 was a tractor at the belt and at the drawbar.
