Introduction
Minneapolis-Moline 2155 Row-Crop Tractor
The Minneapolis-Moline 2155 is a row-crop tractor manufactured by Oliver in Minneapolis, Minnesota, USA, in 1971. Designed for demanding agricultural applications, this 156-horsepower machine combines a robust 6-cylinder engine with a versatile transmission system.
Engine and Power
The tractor is powered by a 504 cubic-inch (8.3 L) 6-cylinder LP gas engine. It is liquid-cooled and operates at a rated speed of 1800 RPM. The engine configuration includes a dry element air cleaner to ensure consistent performance under field conditions.
Transmission and Drivetrain
The 2155 utilizes the Minneapolis-Moline Ampli-Torc transmission, featuring a two-speed power shift design. It provides 10 forward and 2 reverse gears, allowing for precise speed adjustment. The drivetrain includes a 355.6 mm dry disc clutch and outboard planetary final drives for improved torque delivery to the wheels.
Hydraulics and PTO
The hydraulic system is an open-center type, delivering a pump flow of 20 gallons per minute (75.7 lpm) at a maximum pressure of 2000 psi (137.9 bar). It supports two or three valves. The rear independent PTO offers both 540 and 1000 RPM settings, both engaged at 1800 engine RPM, and utilizes a wet disc clutch for smooth operation.
Mechanical and Operator Environment
Built with a two-wheel drive configuration, the tractor features power steering and dry disc brakes for maneuverability. The operator station is open by default, with an optional cab available that includes heating and air conditioning. The wheelbase is 104.25 inches (264 cm), providing a stable platform for field work.
Conclusion
The Minneapolis-Moline 2155 is a heavy-duty row-crop tractor suited for large-scale agricultural operations requiring significant traction and hydraulic capability. Its combination of a high-displacement engine and a versatile power-shift transmission makes it a reliable choice for intensive cultivation and heavy implement operation.
