Introduction
J.I. Case 312-B High-Clearance Tractor
The J.I. Case 312-B is a high-clearance tractor manufactured in 1958 in Rock Island, Illinois, USA. With only 48 units produced, this model is a rare example of mid-century American agricultural machinery, designed for specialized tasks requiring increased ground clearance.
Engine and Performance
The tractor is powered by a 4-cylinder, liquid-cooled gasoline engine with a displacement of 148 cubic inches (2.4 liters). It operates at a rated speed of 1750 RPM and features a compression ratio of 7.1:1. The engine bore and stroke are measured at 3.375 by 4.125 inches (86 by 105 mm). For air intake protection, the unit utilizes an oil bath air cleaner, and it is equipped with an electric starter for reliable ignition.
Transmission and Drivetrain
The 312-B offers two transmission configurations to suit different operating requirements. The standard setup is a 4-speed transmission providing 4 forward gears and 1 reverse gear. An optional Tripl-Range transmission is also available, expanding the versatility to 12 forward gears and 3 reverse gears. The tractor is configured exclusively as a two-wheel drive machine.
Conclusion
Given its limited production run of 48 units and its specific high-clearance design, the J.I. Case 312-B serves primarily as a historical piece for collectors. Its mechanical specifications indicate a machine suited for light-duty agricultural operations requiring specific vertical clearance under the chassis.
