John Deere 7020er-Baureihe
3 models in this series
John Deere 7020 series – six-cylinder diesels from Waterloo, 2003 to 2006, types 7220 to 7420, 6,788 cc, 81 to 99 kW, torque 448 to 561 Nm
The John Deere 7020 series was built from 2003 to 2006 at the Waterloo plant in Iowa, USA, and covered the mid-range standard tractor class there for the North American market. The register lists the types 7220, 7320 and 7420 here, with the two stronger models additionally listed as a four-wheel-drive version (A). All three models are built around the same six-cylinder diesel engine of 6,788 cc as the sister series built at the same time in Mannheim, but with its own power steps for the American market.

The register lists 3 versions here with 81 to 99.4 kW from the common six-cylinder of 6,788 cc at 2,100 to 2,300 rpm, torque of 448 to 561 Nm, kerb weights of 5,366 to 5,900 kg, a length of 4,471 mm, a width of 2,438 mm and a height of 2,865 mm.
The 7020 series covered the mid power segment in North American farming and competed with comparable standard tractors from Case IH and New Holland, which served similar arable and livestock holdings in the same period, often paired with a front loader for yard and feeding work.
When buying a used 7020 series model, the key points are operating hours and service history of the six-cylinder engine, condition of clutch and gearbox, and tightness of the hydraulics, plus corrosion on cab and chassis and the condition of the front axle on four-wheel-drive versions; spare parts are well available through regular John Deere parts channels.
