ENGINE DETAIL
The Case 15-27 tractor features a robust 4-cylinder kerosene engine with a significant displacement of 381.7 ci (6.3 L), providing adequate torque for field operations. Its low rated RPM of 900 enhances durability while demanding operator engagement due to the hand-crank starter, which may pose challenges for ease of use. The 44-quart coolant capacity is beneficial for maintaining optimal engine temperature during prolonged use, supporting efficient cooling in demanding agricultural applications.

TRANSMISSION
The Case 15-27 tractor features a simple gear transmission with 2 forward and 1 reverse gear, making it suitable for basic agricultural tasks in flat terrain. This limited gear ratio may pose challenges in maneuverability and speed adjustment during varied field operations, potentially affecting efficiency. However, its straightforward design offers reliability and ease of maintenance, appealing to operators who prioritize simplicity in function.

MECHANICAL
The Case 15-27 tractor features a 4x2 2WD chassis, which offers enhanced maneuverability in flat terrains but may struggle in adverse conditions such as mud or steep inclines. The manual steering system is straightforward but can lead to operator fatigue over extended use. With a 2-speed gear transmission, this tractor provides basic operational flexibility, suitable for light-duty tasks but may lack the efficiency of advanced transmission systems in more demanding applications.

J.I. CASE 15-27 TIRES
The Case 15-27 tractor features a robust tire configuration, with 32x6 steel front tires providing good maneuverability in tight spaces and 52x14 steel rear tires that enhance traction and stability in heavy loads. The advantages of this setup include improved weight distribution and minimized slippage in agricultural applications. However, the trade-off could be reduced ride comfort on uneven terrains, which may impact operator fatigue during prolonged use.

DIMENSIONS & TIRES
The Case 15-27 tractor, weighing 6,460 lbs (2,930 kg), features front tires sized 32x6 and rear tires 52x14, optimizing stability and traction for diverse agricultural applications. The wide rear tires enhance flotation in soft soil, reducing compaction, while the narrower front tires ensure maneuverability in tighter spaces. However, weight distribution must be carefully managed to prevent front-end lift, especially when utilizing the tractor for heavy-duty implements.
