ENGINES OVERVIEW
The Minneapolis-Moline 445 tractor is available in three engine configurations: a 3.4L 4-cylinder gasoline, a 3.4L 4-cylinder diesel, and a 3.6L 4-cylinder gasoline variant, offering flexibility in fuel choice. The gasoline engines are typically lighter and have quicker throttle response, which can be advantageous for lighter applications, while the diesel engine provides higher torque for heavy-duty tasks, enhancing overall productivity. It's essential to consider your specific operational needs and fuel availability when selecting the appropriate engine type for optimal performance and efficiency.

ENGINE DETAIL 1
The Minneapolis-Moline 445 features a 206 ci (3.4 L) gasoline engine with a low compression ratio of 7.3:1, contributing to its robust torque output at a rated RPM of 1550, making it suitable for tasks requiring steady power over extended periods. Its oil bath air cleaner provides effective filtration, while the carbureted fuel system ensures straightforward maintenance, albeit with less efficiency compared to modern EFI systems. Be cautious of the relatively limited coolant capacity (13.5 qts), as this may affect cooling efficiency during prolonged high-load operations.

MINNEAPOLIS-MOLINE 445 ENGINES
The Minneapolis-Moline 445 features a choice of three engine options: 3.4L and 3.6L 4-cylinder gasoline and diesel variants, offering flexibility in fuel type based on user preference or operational requirements. The 17-gallon fuel tank supports longer operational hours, while the auxiliary 0.875-gallon tank can be an asset for low-compression engine options, enabling extended range for those configurations. However, users should consider potential fuel efficiency differences between gasoline and diesel within the same model, as well as maintenance implications of engine type selection.

MECHANICAL
The Minneapolis-Moline 445 features a 4x2 2WD chassis, providing limited traction on uneven terrain, which can be a disadvantage in hilly or muddy conditions. Its 10-speed two-speed powershift transmission allows for smooth gear transitions, optimizing engine performance for various farming tasks. The open operator station enhances visibility but may expose the operator to outdoor elements, which is a consideration for comfort during prolonged use.
