Introduction

Allis Chalmers 8070 Row-Crop Tractor

The Allis Chalmers 8070 is a row-crop tractor produced in West Allis, Wisconsin, between 1982 and 1985. Rated at 189 horsepower, this model was designed for heavy-duty agricultural operations, reflecting the engineering standards of the series during the mid-1980s.

Engine and Performance

The tractor is powered by the Allis Chalmers 670I engine, a 7.0-liter, 6-cylinder liquid-cooled turbocharged intercooled diesel unit. It operates at a rated speed of 2400 RPM. The engine cooling system has a capacity of 34.1 liters, while the lubrication system requires 18.0 liters of oil.

Transmission and Drivetrain

Two transmission configurations were available: a 20-speed partial power shift offering 20 forward and 4 reverse gears, and an Allis-Chalmers 12-speed transmission with 12 forward and 2 reverse gears. The tractor features a differential lock and hydraulic wet disc brakes, with options for both two-wheel and four-wheel drive systems.

Hydraulics and Hitch

The hydraulic system utilizes a closed-center load-sensitive design providing a total flow of 170.3 liters per minute. This system supports the rear hitch, which is categorized as Type III/II and offers a lift capacity of 3,719 kg at 610 mm behind the lift point.

Operator Environment

The machine is equipped with the standard Acousta cab, which includes climate control features such as heating and air conditioning to maintain operator comfort. Steering is facilitated by a hydrostatic power system.

Conclusion

The Allis Chalmers 8070 is a high-capacity row-crop tractor suitable for large-scale farming applications requiring significant hydraulic output and diverse transmission options. Its combination of a turbocharged engine and robust hydraulic capacity makes it a versatile tool for heavy field work.
