The John Deere 1020 tractor is quite an old machine from the ‘New Generation’ series of tractors. This tractor had a very long production run that lasted from 1965 up until 1973. The tractor is powered by one of 2 different engines, both of which are made by JD themselves. The first is a diesel engine that is naturally aspirated. This engine is a 3 cylinder model that has a liquid cooling system to prevent it from overheating and has a total displacement of 2.5 liters. This diesel engines fires at a compression ratio of 16.7 to 1. The second choice is a gasoline model that is naturally aspirated also. This engine also has 3 cylinders and is liquid cooled. The gas engine fires at a compression ratio of 7.5 to 1. Both engine choices for the JD 1020 use a paper air filter to stop small particulate matter from entering into the engine where it can potentially clog it up.

Both engines on the John Deere 1020 use the same gearbox. This is an unsynchronized transmission that gives the tractor a total of 4 speeds going forwards and 4 for reversing. It allows the JD 1020 to reach a top speed of 26.7 kph (16.6 mph) going forwards. The operator uses a dry clutch for changing gears.

The weight of the John Deere 1020 varies depending on the engine built into it. With the diesel engine, it has a total weight of 2209 kg (4870 lbs), while with the gasoline engine, it’s total weight comes to 2145 kg (4730 lbs). The safe maximum ballasted weight of the JD 1020 is 2701 kg (5955 lbs). The wheels on the tractor that support this weight are fairly standard. The front wheels each measure 5.5-16 (5.5 inch width, 16 inch rim diameter). The rear wheels each measure 13.6-28 (13.6 inch width, 28 inch rim diameter). The other larger models in the same series as this one are the John Deere 2020 and the John Deere 3020 tractors.
