ENGINE DETAIL
The Case 311-B tractor features a liquid-cooled, 4-cylinder engine with a displacement of 148ci (2.4L) and a carbureted fuel system, which may result in less efficiency compared to modern fuel injection systems. With a low compression ratio of 7.1:1 and a maximum rated RPM of 1900, it is ideal for steady, low-speed tasks, making it suitable for applications like plowing or hauling. However, its oil bath air cleaner may demand more maintenance than paper filters, presenting a challenge for users seeking low upkeep.

DIMENSIONS & TIRES
The Case 311-B tractor features a 84.5-inch wheelbase in tricycle configuration, which enhances maneuverability but may compromise stability on uneven terrain compared to the 79.5-inch GP wheelbase. Weighing 4,076 lbs (1,848 kg) provides a solid foundation for plowing tasks, but the relatively narrow front tires (5.50-16) could lead to challenges in traction on soft soils. The combination of rear tires (11-28) supports substantial power transmission, making it suitable for medium to heavy-duty farming applications where traction and weight distribution are critical.
