Introduction
Muir-Hill 171: 4WD Agricultural Tractor
The Muir-Hill 171 is a heavy-duty four-wheel-drive tractor produced in Manchester, England, between 1975 and 1984. As part of the 141 series, this machine was designed to provide significant tractive force for demanding agricultural operations.
Engine and Performance
The tractor is powered by a Perkins V8.540 eight-cylinder liquid-cooled diesel engine. With a displacement of 8.8 liters (539 cubic inches) and direct fuel injection, it generates a rated power of 177 hp (132 kW). The engine is engineered to deliver 410 lb-ft (556 Nm) of torque at 1600 RPM, providing the necessary low-end power for heavy field work.
Transmission and Drivetrain
The drivetrain utilizes an Eaton-Fuller T4510 gear-type transmission, offering 10 forward speeds and 2 reverse speeds. Power is transferred through a 355.6mm dry disc clutch to a 4WD system featuring planetary final drives. The machine is equipped with hydraulic wet disc brakes and power steering to ensure reliable control and maneuverability under load.
Hydraulics and PTO
The hydraulic system is an open-center type, delivering a pump flow of 24 gpm (90.8 lpm) across four valves. It features a combined capacity of 22.8 gallons for the three-point hitch and steering, with a separate 17.4-gallon circuit dedicated to the PTO. The independent rear PTO operates at 1000 RPM, standardizing connectivity for high-power implements.
Dimensions and Operator Environment
With a wheelbase of 86.6 inches (219 cm) and an operating weight of 14,000 lbs (6350 kg), the tractor is built for stability. It is fitted with 18.4/15x34 tires on both the front and rear axles. The operator station consists of a standard cab equipped with a heater, with optional air-conditioning available to improve comfort during extended operation.
Conclusion
The Muir-Hill 171 is a robust, high-horsepower tractor tailored for large-scale farming and heavy traction tasks. Its combination of a Perkins V8 engine and a reliable Eaton-Fuller transmission makes it a durable choice for operators requiring consistent performance in challenging field conditions.
