Introduction
Minneapolis-Moline ZA, Row-Crop Tractor
The Minneapolis-Moline ZA is a row-crop tractor manufactured in Minneapolis, Minnesota, between 1949 and 1953. It was designed as a versatile agricultural machine, offering a power output of 40 hp for varied fieldwork applications during the mid-20th century.
Engine and Performance
The tractor is powered by a liquid-cooled, 4-cylinder Minneapolis-Moline 206B-4 gasoline engine. With a displacement of 206 cubic inches (3.4 liters) and a compression ratio of 6.19:1, the engine is rated at 1500 RPM. It utilizes an oil bath air cleaner and requires a 6-volt electrical system for starting.
Transmission and Drivetrain
The drivetrain features a two-wheel-drive configuration paired with an unsynchronized gear transmission. It offers five forward gears and one reverse gear, controlled by a dry disc clutch. Final power delivery to the wheels is achieved through a bull gear system.
Operator Environment and Controls
The ZA is equipped with an open operator station designed for visibility. Steering is performed via a manual system, and braking is managed through mechanical drum brakes. The tractor includes a 540 RPM rear power take-off (PTO) to accommodate various implements.
Dimensions and Stability
The tractor features a ground clearance of 25 inches (63 cm). It allows for adjustable tread widths, with front treads ranging from 7.75 to 12.875 inches (depending on configuration) and rear treads adjustable between 54 and 88 inches. Standard agricultural tires include 5.50x16 front and 11x38 rear sizes.
Conclusion
The Minneapolis-Moline ZA is a robust, mechanically straightforward tractor suited for general row-crop agricultural tasks. Its durable construction and adjustable dimensions make it a notable example of American tractor engineering from the early 1950s.
