The John Deere 720 tractor is part of large series that has long since stopped production (production ceased over 50 years ago in 1958 in fact!). Other models in the series include the larger John Deere 820 as well as the smaller John Deere 320 and the John Deere 420 tractor models. There are actually 3 versions of the JD 720, a standard version as well as a row crop model and high crop version.

In total there are 4 different engine choices on the John Deere 720 tractor. They are a gasoline, LP gas, all fuel and diesel engine. The gasoline, LP gas and all fuel engines have a total displacement of 5.9 liters, while the diesel model has a displacement of 6.2 liters. All of the engines are naturally aspirated, are twin cylinder and all of them use a liquid cooling system to keep the engine from overheating. The engines are all keystarted. Power from the engine gets transferred to the rear wheels of the JD 720 through an unsynchronized gearbox. This gives the tractor 6 speeds going forwards and 1 for reversing. It’s top speed traveling forwards is 18.2 kph (11.3 mph), while in reverse, it’s top speed it’s much slower topping out at 5.4 kph (3.3 mph). The rear wheels, through which power is transferred differ in size, depending on the model. The standard model has wheels which measure 14-30 (14 inch width, 30 inch rim diameter), the high crop model’s rear tires measure 13.6-38 (13.6 inch width, 38 inch rim diameter) and the row crops tires measure 12-38 (12 inch width, 38 inch rim diameter).
