ENGINE DETAIL
The Chamberlain 40KA tractor features a robust 2-cylinder, liquid-cooled, horizontally-opposed engine with a displacement of 6.0 L, delivering 48.5 hp at a low operational speed of 1200 RPM. Its thermosiphon cooling system is beneficial for efficient heat management but can be less effective in extreme conditions compared to forced cooling systems. Ideal for medium-scale farming, its kerosene fuel type may offer a cost advantage, though availability and efficiency compared to modern diesel engines should be considered.

CHAMBERLAIN 40KA ENGINE
The Chamberlain 40KA tractor features a powerful 6.0L 2-cylinder kerosene engine, which delivers efficient fuel consumption, ideal for agricultural tasks. Its substantial 27.6-gallon fuel tank allows for extended operational periods without frequent refueling, while the 4.2-gallon auxiliary fuel tank provides added flexibility for remote work scenarios. However, the reliance on kerosene may limit fuel availability in some regions, posing a challenge for accessibility and convenience.

TRANSMISSION
The Chamberlain 40KA tractor features a sliding gear transmission, allowing for smooth gear transitions, which enhances operational efficiency. With a gearbox comprising 9 forward and 3 reverse gears, it offers versatile power handling for various agricultural tasks and terrain challenges. However, the complexity of the sliding gear system may demand precise operator skill to minimize wear and ensure durability.

MECHANICAL
The Chamberlain 40KA features a 4x2 2WD chassis, suitable for lighter agricultural tasks and potentially limiting traction on uneven terrains. Its mechanical recirculating ball steering offers good precision but may require more effort compared to hydraulic alternatives. The 9-speed transmission provides versatility in speed selection, making it adaptable for varied field conditions, though it may not match the ease of shifting found in modern power-shift systems.

CHAMBERLAIN 40KA TIRES
The Chamberlain 40KA features a robust tire configuration with 7.50x18 agricultural front tires and 15.00x30 rear tires, providing enhanced traction and stability for field operations. The larger rear tires increase weight distribution, improving performance on uneven terrain; however, they may limit maneuverability in tighter spaces. It's ideal for heavy tillage applications, but operators should consider potential challenges with transport speed due to the tractor's gearing ratio and overall weight.

DIMENSIONS & TIRES
The Chamberlain 40KA tractor features a compact wheelbase of 83 inches, enhancing maneuverability in tight workspaces, which is beneficial for smaller fields or landscaping tasks. Weighing 8500 lbs, it offers stability during heavy-duty tasks but may require a more powerful towing vehicle for transport. The tire specifications, with wider rear tires of 15.00x30, provide better traction in rough terrains, while the front tires (7.50x18) support improved steering control, making it suitable for diverse agricultural applications.
