ENGINE DETAIL 1
The Case 811-B tractor is powered by a 4-cylinder gasoline engine with a displacement of 251 cubic inches (4.1L) and a compression ratio of 6.5:1, designed for reliable performance at a rated RPM of 1800. Its oil bath air cleaner aids in efficient filtration, extending engine life under demanding conditions. While the low compression ratio ensures smooth operation, it may reduce power output compared to modern higher-compression engines, making it more suitable for lighter tasks or as a vintage collector's item in agricultural applications.

ENGINE DETAIL 2
The Case 811-B tractor features a J.I. Case LP gas 4-cylinder engine with a displacement of 251 ci (4.1 L) and a compression ratio of 8.0:1, providing moderate power output at a rated RPM of 1800. Its oil bath air cleaner aids in filtration, enhancing engine longevity by reducing dust intake under tough conditions; however, this can be a challenge in maintenance frequency. Ideal for agricultural applications requiring reliable torque and efficiency, the 811-B is especially advantageous in environments where LP gas is readily available, offering better emissions compared to diesel alternatives.

MECHANICAL
The Case 811-B tractor features a two-wheel drive system, providing sufficient traction for light to moderate agricultural tasks; however, it may struggle in challenging terrains compared to four-wheel drive models. The mechanical disc brakes offer reliable stopping power but require proper maintenance to ensure optimal performance. Its open operator station with power steering enhances operator comfort and maneuverability, making it suitable for use in smaller fields or tight spaces.

J.I. CASE 811-B TIRES
The Case 811-B tractor utilizes front tires sized 6.00-16 and rear tires sized 15.5-38, providing a balance of stability and traction suitable for various agricultural applications. The tire configuration facilitates excellent maneuverability in tight spaces while ensuring sufficient power transfer to the ground for heavier implements. Challenges may include tire wear if operated consistently on hard surfaces; proper inflation and tire maintenance are critical for optimal performance.

DIMENSIONS & TIRES
The Case 811-B tractor features a wide front wheelbase of 101.75 inches and a tricycle configuration, which enhances stability and maneuverability in various terrains, particularly beneficial for narrow rows in row-crop applications. Weighing 6,775 lbs and equipped with a robust rear tire size of 15.5-38, it offers good traction for heavy-duty tasks; however, the lighter front tire (6.00-16) may impact front-end stability under heavy load conditions. In scenarios requiring tight turns and agility, the tricycle configuration can be advantageous, though it may present challenges in terms of ride comfort and lateral stability on uneven ground.
