ENGINE DETAIL
The Minneapolis 12-25 tractor features a kerosene-powered 4-cylinder engine with a significant displacement of 445.3 ci (7.3 L), enhancing its torque output for heavy-duty tasks. With a bore/stroke ratio of 4.50x7.00 inches (114 x 178 mm), it favors torque production over high RPMs, while its low rated RPM of 750 indicates that it is designed for sustained power rather than speed. The hand crank starter may pose a challenge in terms of convenience and ease of use, especially in colder conditions or for operators unfamiliar with manual starting procedures.

MINNEAPOLIS 12-25 ENGINE
The Minneapolis 12-25 tractor is equipped with a 7.3L, 4-cylinder kerosene engine, offering robust performance for agricultural applications. Its kerosene fuel type provides cleaner combustion compared to gasoline, potentially reducing emissions and enhancing engine longevity. However, the tractor's reliance on kerosene may limit availability in certain regions, and farmers must ensure compatibility with local fuel infrastructure to maximize operational efficiency.

TRANSMISSION
The Minneapolis 12-25 tractor features a gear type transmission with 2 forward and 1 reverse gear, which simplifies operation and enhances maneuverability, particularly in tight spaces. While the limited gear range may restrict speed and versatility on varying terrains, it can be advantageous for tasks requiring precise control like plowing or hauling in confined areas. Operators should consider the tractor's suitability for specific applications where simplicity and ease of use outweigh the need for multiple gear options.

MECHANICAL
The Minneapolis 12-25 tractor features a 4x2 two-wheel drive (2WD) chassis, providing sufficient traction for light to moderate agricultural tasks but may struggle in uneven terrain or adverse conditions due to its lack of all-wheel drive. Its manual steering system may require more physical effort, potentially reducing operator comfort during extended use. The 2-speed gear transmission offers basic speed options but limits versatility in varying field conditions compared to models with more advanced transmission systems.

MINNEAPOLIS 12-25 TIRES
The Minneapolis 12-25 tractor features extensive agricultural capability with its 56x12 steel rear tires, providing enhanced traction and durability for field work. Its weight distribution and steel composition are advantageous for deep tillage and challenging terrain, but can limit maneuverability and increase soil compaction. Optimal scenarios for use include heavy-duty farming operations where durability and traction are paramount, although care should be taken to mitigate soil structure damage.

DIMENSIONS & TIRES
The Minneapolis 12-25 tractor, with a weight of 6,400 lbs (2,903 kg), provides substantial traction, making it suitable for heavier tillage and pulling tasks. Its rear tires measuring 56x12 offer a broader footprint, which can enhance stability on uneven terrain but may lead to increased soil compaction. Users should consider the tractor's weight distribution and tire dimensions for optimal performance in specific agricultural applications, particularly in softer ground conditions.
