ENGINES OVERVIEW

The Oliver 2155 is equipped with a powerful Minneapolis-Moline engine, available in a 9.6L 6-cylinder diesel or an 8.3L 6-cylinder LP gas configuration. The diesel variant offers superior torque and fuel efficiency, making it ideal for heavy-duty applications, while the LP gas option provides cleaner emissions and quieter operation. However, availability of parts and specific fuel requirements can pose challenges, particularly for vintage models, impacting maintenance and operational flexibility.

ENGINE DETAIL 1

The Oliver 2155 tractor features a robust 9.6L Minneapolis-Moline diesel engine with a compression ratio of 15.3:1, providing excellent torque for heavy-duty applications. Its 6-cylinder configuration and a rated RPM of 2200 ensure optimal performance in both agricultural and industrial tasks, while the dry element air cleaner aids in maintaining engine cleanliness and efficiency. Challenges may include sourcing parts for older models and ensuring adequate cooling during prolonged use due to its large displacement.

ENGINE DETAIL 2

The Oliver 2155 tractor is powered by a Minneapolis-Moline LP gas 6-cylinder engine with a substantial 504ci (8.3L) displacement, offering a robust torque characteristic ideal for heavy-duty applications. Its dry air cleaner ensures efficient filtration, while the engine's rated RPM of 1800 balances power output with operational efficiency, making it suitable for both agricultural use and industrial tasks. However, the reliance on LP gas may pose challenges in fuel availability and cost, especially in remote areas.

TRANSMISSION

The Oliver 2155 features a Minneapolis-Moline Ampli-Torc transmission with a two-speed power shift, allowing for seamless gear changes, which enhances productivity during varied field operations. With 10 forward and 2 reverse gears, it offers a broad speed range suitable for both high-speed transport and low-speed tasks like plowing. However, the 355.6mm dry disc clutch may require more frequent maintenance under heavy load, potentially impacting operational efficiency in prolonged use scenarios.

MECHANICAL

The Oliver 2155 tractor features a 4x2 2WD chassis, which offers simple maintenance but may limit traction on uneven terrain compared to 4WD options; this is advantageous for flat fields. Its outboard planetary final drives enhance durability and efficiency, offering a good torque-to-weight ratio, while the power steering and dry disc brakes provide ease of operation and reliability. The optional heated and air-conditioned cab can increase operator comfort during extended use, making it a versatile choice for various agricultural tasks.
