Farmall Super C Overview
Farmall Super C, produced by Farmall (a division of International Harvester) from 1951 to 1954, pairs a 122.7 ci (2.0 L) gasoline engine with a simple four-forward, one-reverse sliding-gear transmission.
This mid-century design fits light row-crop work and general farm tasks, and it remains a common target for restoration and parts matching. Public operator manuals and test reports provide a solid basis for evaluating condition and configuration when serial range and build year are known.
Before buying or ordering parts, verify the tractor's serial range and configuration against documented options to avoid mismatches.

Parts Checks Before Ordering
Do not order Farmall Super C parts from the model name alone. Match the part to the tractor's serial range, engine, transmission, PTO setup, and build year before choosing service parts.
Filters, fluids, belts, electrical parts, clutch and PTO parts, and hydraulic parts can vary by setup. Exact part numbers require a parts catalog, manual, or trusted supplier source before they become recommendations.
Accuracy Note
Tractor specifications can vary by year, region, factory configuration, installed equipment, and later repairs. Match serial range, engine, transmission, PTO setup, and model code before ordering parts or doing service work.
