Allis Chalmers 7020The Allis Chalmers 7020 is a 2WD row-crop tractor manufactured by Allis Chalmers in West Allis, Wisconsin, USA from 1978 to 1981. The Allis Chalmers 7020 is equipped with a 4.9 L (301.0 cu·in) six-cylinder diesel engine and one of three transmissions: a partial power shift transmission with 16 forward and 4 reverse gears, a partial power shift transmission with 20 forward and 4 reverse gears or a partial power shift transmission with 12 forward and 2 reverse gears.

The Allis Chalmers 7020 row-crop tractor used the Allis Chalmers 649I engine. It is a 4.9 L, 4,932 cm2, (301.0 cu·in) six-cylinder turbocharged intercooled diesel engine with 98.0 mm (3.86 in) of the cylinder bore and 108.0 mm (4.25 in) of the piston stroke. The compression ratio rating is 16.25:1. This engine produced 148.1 PS (108.9 kW; 146.0 HP) at 2,300 rpm of output power.

The Allis Chalmers 7020 is equipped with hydrostatic power steering, differential hydraulic wet disc brakes, the Acousta-Cab, and 193.0 liters (51 US gal.; 42.5 Imp. gal) fuel tank.
