Introduction
Allis Chalmers 7080 Row-Crop Tractor
The Allis Chalmers 7080 is a heavy-duty row-crop tractor produced between 1975 and 1981 in West Allis, Wisconsin, USA. Positioned as a high-horsepower model of its era, it was designed for demanding field operations and large-scale agricultural tasks.
Engine Specifications
The tractor is powered by the Allis Chalmers 670HI, a 7.0-liter, 6-cylinder liquid-cooled diesel engine. It utilizes intercooled turbocharging and features a 16:1 compression ratio. With a rated speed of 2550 RPM, the engine delivers 210 horsepower (156.6 kW), providing the necessary torque for heavy draft work.
Transmission and Drivetrain
The 7080 is equipped with the Allis-Chalmers Power Director transmission, a partial power shift system offering 20 forward and 4 reverse gears. It features two ranges and a two-range power shift controlled by foot buttons, allowing the operator to adjust speeds without clutching. The machine is configured as a two-wheel drive platform with differential hydraulic wet disc brakes and power steering.
Hydraulics and PTO
The hydraulic system utilizes a closed-center design with a total flow capacity of 47 gpm (177.9 lpm), managed by 2 or 3 valves. This high flow rate is engineered to support demanding implements. The tractor features an independent rear PTO operating at 1000 RPM, paired with a rear three-point hitch capable of lifting 6,680 lbs (3030 kg) at 24 inches behind the lift point.
Operator Environment and Dimensions
The operator station features the Acousta cab as standard equipment, which includes heating and optional air conditioning. The tractor has a wheelbase of 106 inches and a total weight of 13,638 lbs. Various tire configurations were available to accommodate different soil conditions and row spacings, supported by a heavy-duty 4-inch diameter rear axle.
Conclusion
The Allis Chalmers 7080 is a robust, high-performance tractor suited for large-acreage farming. Its combination of a high-capacity hydraulic system, reliable 210-horsepower engine, and flexible partial power shift transmission makes it a capable machine for primary tillage and heavy draft applications.
