Introduction
Massey-Harris 555: Technical Overview of the Standard-Tread Tractor
The Massey-Harris 555 is a standard-tread agricultural tractor manufactured between 1955 and 1958. Designed as a robust workhorse for mid-century farming operations, this two-wheel-drive machine features a liquid-cooled diesel powertrain and an open operator station configuration.
Engine and Performance
The tractor is powered by a Continental J382D diesel engine, a 4-cylinder, liquid-cooled unit with a displacement of 382 cubic inches (6.3 liters). It produces 78 horsepower at a rated engine speed of 1350 RPM, providing steady torque for agricultural field work.
Transmission and Drivetrain
The drivetrain utilizes a mechanical transmission system consisting of 4 forward gears and 1 reverse gear. Power transfer is managed through a dry disc clutch, which provides a straightforward and reliable interface for the operator to engage the two-wheel-drive system.
Power Take-Off and Hydraulics
The Massey-Harris 555 is equipped with a rear power take-off (PTO) operating at a standard 540 RPM. This PTO speed is achieved when the engine is running at 1350 RPM, ensuring compatibility with implements designed for this specific output standard.
Dimensions and Chassis
The tractor has a wheelbase of 88.5 inches (224 cm) and a total weight of 7500 lbs (3402 kg), contributing to its stability during operation. It is fitted with agricultural tires, utilizing 7.50-18 tires on the front and 14-34 tires on the rear to maintain traction across varied soil conditions.
Conclusion
With its simple mechanical design and substantial build, the Massey-Harris 555 serves as a classic example of late 1950s agricultural engineering. Its configuration is well-suited for general field operations where consistent power and straightforward maintenance are required.
