ENGINE DETAIL 2
The Minneapolis-Moline UB tractor is powered by a D283-4 diesel engine, providing a robust 4.6L displacement which enhances torque and efficiency for various agricultural tasks. Its bore and stroke dimensions (4.25x5.00 inches) indicate a long-stroke design that promotes low-end torque, making it ideal for heavy-duty applications like plowing and hauling. While the diesel engine offers high durability and fuel efficiency, maintenance of the liquid-cooling system is critical to prevent overheating, especially in prolonged use.

ENGINE DETAIL 3
The Minneapolis-Moline UB tractor's 283.7 ci (4.6 L) 4-cylinder engine operates at a low 1300 RPM, suitable for steady torque applications in farming or light industrial work. Its oil bath air cleaner enhances filtration, which contributes to engine longevity; however, maintenance can be more labor-intensive. The 8:1 compression ratio and LP gas fuel type provide clean emissions, making it advantageous for operators focused on environmental impact, though LP gas availability may restrict operational flexibility in some regions.
