Introduction
Minneapolis-Moline 2055 Row-Crop Tractor
The Minneapolis-Moline 2055 is a row-crop tractor manufactured by Oliver in Minneapolis, Minnesota, between 1971 and its production cycle. Designed for heavy-duty agricultural operations, it provides 122 horsepower and was positioned as a reliable solution for mid-to-large scale farming tasks.
Engine and Performance
The tractor is powered by a 6-cylinder, liquid-cooled LP gas engine with a displacement of 504 cubic inches (8.3 liters). It features a bore and stroke of 4.625 by 5.00 inches with a compression ratio of 8.8:1. The engine is rated at 1800 RPM and utilizes a dry-type air cleaner to manage intake in dusty field conditions.
Transmission and Drivetrain
The 2055 is equipped with the Minneapolis-Moline Ampli-Torc transmission system, available in two configurations: a 10-speed version featuring a two-speed power shift (10 forward and 2 reverse gears) or a 15-speed version with a three-speed power shift (15 forward and 3 reverse gears). Both options utilize a 355.6mm dry disc clutch. The tractor offers both two-wheel and four-wheel drive capabilities to suit varying terrain requirements.
Hydraulics and PTO
The hydraulic system utilizes an open-center design, with an optional closed-center configuration available. It provides two or three valves for implement control. The independent rear PTO supports both 540 and 1000 RPM speeds, utilizing a 1.375-inch shaft, and features a wet disc clutch for smooth engagement.
Operator Environment and Dimensions
The tractor features an open operator station as standard, with a factory-optional cab equipped with heating and air conditioning. Operational control is enhanced by power steering and disc brakes. With a standard wheelbase of 103.75 inches and a row-crop wheelbase of 104.5 inches, the machine is designed for stability in row-crop applications. The rear tread is adjustable between 60 and 90 inches.
Conclusion
The Minneapolis-Moline 2055 is a robust, mechanically straightforward tractor suited for demanding field work. Its combination of high-displacement engine power, multiple transmission configurations, and adjustable row-crop dimensions makes it a versatile choice for operators requiring a durable machine for varied agricultural implements.
