John Deere 8020 series (2002–2006) – the third generation of the big tractors from Waterloo: 8120 to 8520, the number as power step, T for the tracked version, PowerTech six-cylinder of 8.1 litres, 147 to 217 kW

The 8020 series followed the 8010s in 2002 and was the third generation of the big tractors with which John Deere had served the 200 to 300 hp class from Waterloo, Iowa, since 1994 – recognisable by the new cab, the Independent Link front-axle suspension and the engine with increased power. The type logic: 8 marks the series, the middle digit the power step – 8120 about 200 hp, 8220 220 hp, 8320 250 hp, 8420 270 hp, 8520 about 295 hp – 20 the generation, T the tracked version with rubber-belt undercarriage, represented in the register throughout from the 8120T to the 8520T. The engine in all models is the PowerTech six-cylinder of 8.1 litres at 2,200 rpm, with common-rail injection and power boost; the transmission is the 16-speed PowerShift, optionally with AutoPowr as stepless version.

The register lists 7 versions with 147.2 to 217.1 kW from the six-cylinder of 8,134 cm³, torque from 857 to 1,030 Nm, unladen weights from 8,214 to 12,374 kg, lengths from 5,530 to 5,850 mm, widths from 2,540 to 2,634 mm and heights from 3,122 to 3,200 mm.

The 8020s are the tractors with which the tracked version gained a foothold in Europe – the 8420T and 8520T became the alternative to the Challenger in eastern Germany and Eastern Europe; in 2006 the 8030 series followed with a 9.0 litre engine.

On used tractors, operating hours, engine and common-rail injection, PowerShift transmission (clutch packs, oil history), Independent Link suspension, on T models the rubber belts, rollers and drive wheels, hydraulics and electronics and the service history at the Deere dealer count.
