ENGINE DETAIL
The Case 312-B tractor features a 148 cubic inch (2.4L) four-cylinder gasoline engine with an oil bath air cleaner, which enhances filtration efficiency but may require more maintenance. With a 7.1:1 compression ratio and a rated RPM of 1750, it provides adequate torque for moderate agricultural tasks, though lower RPM may limit performance in high-demand scenarios. While its electric starter offers convenience, the tractor's overall performance can be challenged by its relatively low displacements compared to modern counterparts, which could favor larger operations.

J.I. CASE 312-B ENGINE
The Case 312-B tractor is powered by a J.I. Case 2.4L 4-cylinder gasoline engine, offering a balance of efficiency and power suited for light to moderate agricultural tasks. Its compact size and lightweight design enable maneuverability in tight spaces while maintaining sufficient torque for PTO-driven implements. However, gasoline engines typically offer lower fuel efficiency compared to diesel counterparts, which may increase operating costs over prolonged use in heavy-duty applications.
