Introduction
Minneapolis-Moline G550 Row-Crop Tractor
The Minneapolis-Moline G550 is a row-crop tractor introduced in 1971. Designed for versatility in agricultural operations, this two-wheel-drive machine provides a rated power of 58 horsepower, catering to farmers requiring a stable and reliable utility tractor for field work.
Engine and Performance
The G550 is powered by a liquid-cooled, 6-cylinder Waukesha-Oliver gasoline engine with a displacement of 232 cubic inches (3.8 liters). It operates at a rated speed of 2200 RPM and features an 8:1 compression ratio. Engine longevity is supported by a dry-type air cleaner and a cooling system capacity of 20 quarts (18.9 liters).
Transmission and Drivetrain
The tractor offers two transmission configurations. The Hydra-Power system is a partial power shift transmission providing 12 forward and 4 reverse gears, allowing for on-the-go shifts between direct-drive and a lower range. Alternatively, an unsynchronized gear transmission with 6 forward and 2 reverse speeds is available. Both options utilize a 279.4 mm dry disc clutch for engagement.
Hydraulics and PTO
Equipped with an open-center hydraulic system, the G550 provides a capacity of 14 gallons (53.0 liters) and supports 2 to 4 valves for implement operation. The rear PTO is independent, offering dual-speed capabilities of 540 and 1000 RPM, which allows for compatibility with a wide range of powered implements.
