Introduction
Massey-Harris 101 Senior
The Massey-Harris 101 Senior is a row-crop tractor produced between 1942 and 1946. Manufactured in Racine, Wisconsin, USA, this model represents a significant entry in the Massey-Harris product line during the mid-1940s, distinguished from the 101 Super by its use of a Continental engine.
Engine and Performance
The tractor is powered by a Continental F226 liquid-cooled, 6-cylinder gasoline engine. With a displacement of 226 cubic inches (3.7 liters), the engine produces 40 horsepower. It operates with a compression ratio of 6:1 and features an oil bath air cleaner to maintain performance in dusty field conditions. The electrical system utilizes a 6-volt battery and a generator charging system.
Transmission and Power Take-Off
The 101 Senior is equipped with a gear-type transmission providing 4 forward gears and 1 reverse gear, managed by a dry disc clutch. Power for implements is delivered via a rear transmission-driven PTO, which provides a standard 540 RPM output at a rated engine speed of 1500 RPM.
Chassis and Dimensions
Built with a two-wheel drive configuration, the tractor features manual steering and mechanical internal expanding brakes. The row-crop design offers an adjustable rear tread ranging from 52 to 88 inches (132 to 223 cm). The machine has a total length of 133 inches (337 cm) and a weight of approximately 4,000 lbs (1,814 kg).
Conclusion
The Massey-Harris 101 Senior is a durable, utility-focused tractor designed for row-crop applications. Its combination of a reliable Continental engine and simple mechanical controls makes it a representative example of mid-1940s agricultural engineering, suitable for both historical collection and light-duty field operations.
