ENGINE DETAIL
The Allis Chalmers 6-12 tractor features a Le Roi 2-C gasoline 4-cylinder engine with a displacement of 138.1 cubic inches, offering a robust power output at a low rated RPM of 1200, which optimizes torque for agricultural tasks. Its bore/stroke ratio of 3.125 x 4.50 inches allows for good thermal efficiency and torque characteristics, making it well-suited for heavy-duty operations like plowing and tilling. However, with a coolant capacity of just 14 quarts, overheating could be a concern in sustained, high-load scenarios unless managed properly.

ALLIS CHALMERS 6-12 ENGINE
The Allis Chalmers 6-12 tractor is powered by a Le Roi 2.3L 4-cylinder gasoline engine, offering a balance of power and efficiency for light agricultural tasks. With an 8.5-gallon fuel tank, it provides a reasonable operational range, making it suitable for short to medium-duration fieldwork without frequent refueling. However, the relatively small engine size may limit performance in heavy-duty applications, so consider your workload requirements before selection.

TRANSMISSION
The Allis Chalmers 6-12 tractor features a simple gear transmission with a single forward and reverse gear, optimizing ease of operation for straightforward tasks. While its limited gearing can provide reliability and efficiency in low-speed applications, it may not be suitable for scenarios requiring varied speed control or complex terrain. This design is advantageous for small-scale farming and garden work, where maneuverability and simplicity are prioritized.

MECHANICAL
The Allis Chalmers 6-12 tractor features a 4x2 2WD chassis, which enhances maneuverability in tight spaces but limits traction in slippery conditions. The manual steering system offers simplicity and ease of maintenance, although it may require more effort in challenging terrains. With a 1-speed gear transmission, it is best suited for light, low-speed applications, making it ideal for tasks like mowing or light-duty hauling, but less efficient for varied speed work or heavy loads.

ALLIS CHALMERS 6-12 TIRES
The Allis Chalmers 6-12 tractor features agricultural front tires sized 48x6 and rear tires sized 28x6, offering a robust configuration for soil stability and traction in various field conditions. The use of steel tires may enhance durability but can lead to increased soil compaction, presenting a challenge in softer soils. Ideal for heavy-duty agricultural applications, this tractor excels in tasks requiring consistent power but may not be suited for delicate crops or rugged terrains where flotation is critical.
