ENGINE DETAIL
The Minneapolis 39-57 tractor features a 4-cylinder, liquid-cooled Stearns gasoline engine with a substantial displacement of 617.7 ci (10.1 L), ideal for high torque applications at low RPM, enhancing pulling power. Its bore and stroke dimensions (5.50x6.50 inches) indicate a long-stroke design, which typically improves torque at lower engine speeds but may limit maximum RPM performance. The hand crank starter may pose challenges in cold weather or for less experienced operators, potentially impacting usability in certain farming scenarios.

TRANSMISSION
The Minneapolis 39-57 tractor features a gear type transmission with 2 forward and 1 reverse gear, allowing for a basic yet effective operation in various agricultural tasks. The simplicity of this transmission system offers reliability and ease of maintenance, but the limited forward gears may restrict adaptability in diverse field conditions. Ideal for smaller farms or specific tasks, it may not meet the demands of extensive agricultural operations requiring higher speed variability.

MECHANICAL
The Minneapolis 39-57 tractor features a 4x2 2WD chassis, which provides adequate traction for light to moderate agricultural tasks but may struggle in slippery or uneven terrain. The manual steering and open operator station enhance operator visibility and control, ideal for basic fieldwork, yet may lead to fatigue during prolonged use. The 2-speed gear transmission allows for versatility in speed management, although it limits operational range compared to models with multi-range transmission systems.

MINNEAPOLIS 39-57 TIRES
The Minneapolis 39-57 tractor features robust AG rear tires sized 58x19.5, providing excellent traction and stability on various terrains. The steel construction enhances durability, making it well-suited for heavy-duty agricultural tasks but may increase overall weight, impacting maneuverability. Ideal for plowing and fieldwork, potential challenges include soil compaction and limited performance on softer, uneven surfaces.
DIMENSIONS
DIMENSIONS & TIRES
The Minneapolis 39-57 tractor, weighing 9,695 lbs (4,397 kg), boasts significant traction and stability, primarily due to its robust rear tire size of 58x19.5, which enhances ground contact. This weight and tire configuration is advantageous for heavy-duty agricultural tasks, providing better soil compaction and reduced slippage in challenging terrains. However, the substantial weight may pose challenges in terms of transportability and maneuverability in tighter spaces.
