ENGINE DETAIL
The J.I. Case 812-B tractor features a gasoline 4-cylinder engine with a displacement of 267 ci (4.4L) and a compression ratio of 6.5:1, providing moderate power for agricultural applications. Its oil bath air cleaner enhances engine longevity by effectively filtering dust and particulates, which is critical when operating in dusty fields. However, the relatively low rated RPM of 1800 may limit its performance in high-speed applications, making it more suitable for tasks like plowing and tilling at lower speeds.
