The John Deere 40 is another of JD’s massively popular tractors manufactured over a 2 year production run that lasted from 1953 – 1955 in Dubuque, Iowa. Within this 2 year time frame, almost 50,000 JD 40’s were shipped to farmers, as well as the tractor seeing many different configurations, as was the norm for popular John Deere models back then.

The engine used in the JD 40 was either a 2 cylinder, 1.6 liter gasoline engine made by John Deere themselves or a 2 cylinder, 1.6 liter, all fuel engine, again made by John Deere which is the same as in the John Deere M, the model that preceded the John Deere 40. This provided a maximum of 25hp, which when compared to many large ride on lawn mowers these days produced by JD is not a lot of power at all. The fuel tank that came with this model can hold 39.7 liters of fuel (10.5 US gallons) as well as having an emergency reserve of 3.4 liters (0.9 US gallons). The JD 40 measures 3.31m (130.5 inches) in length while it is 2.27m (90 inches wide).

There are also many other versions of the John Deere 40. The John Deere 40T is a tricycle version which has a tighter turning arc than the regular 40 but it is far more unstable on bumpy, uneven or hilly ground. The 40C is the crawler version which is much heaver than the standard 40. It is is equipped with tracks and a blade for earth moving. The John Deere 40C weighs in at 2400kg (4500lbs) up to 2720kg (6000lbs) when fully loaded with a blade, fuel, oil and hydraulic fluid. The tracks on the 40C are 12 inches wide so it never slips even in the most slippy and wet conditions. The John Deere 40V was sold as a ‘vegetable’ tractor and differed from the others in that it had a much higher ground clearance. The John Deere 40w was built specifically as a row crop tractor, but not that many were produced.
