Farmall Super H

Last Updated: July 2024

Overview

The Farmall Super H is a 2WD row-crop tractor manufactured by Farmall, a division of International Harvester, between 1953 and 1954. This model is powered by an International Harvester C164 four-cylinder gasoline engine, rated at 40.81 horsepower and 1,650 RPM. The engine produces a maximum torque of 171 lb.-ft. (232 Nm) at 1200 rpm and has a torque rise of 22.4% with a power increase of 12.3% at 1655 rpm. Equipped with a liquid-cooling system and a sliding gear transmission that offers 5 forward gears and 1 reverse, this tractor was designed for various farm tasks. It features a simple yet efficient mechanical disc braking system, a manual steering setup, and an electric starter system. The operating weight of the Farmall Super H is 3,875 pounds, with dimensions measuring 133 inches in length, 75.5 inches in width, and 85 inches in height. It provides the operator with basic accommodations including an open operator station. The Category 3 hitch at the rear is assumed given the era and style of the tractor, though specific lift capacity is unknown. The Super H runs on agricultural tires that allow it to navigate through different terrains typically encountered on a farm. Additional performance details include a fuel efficiency of 13.90 Hp.hr/gal (2.74 kW.h/l) at the standard PTO speed of 540 rpm and a fuel consumption of 3.27 Gal/hr (12.38 l/h) at 1452 rpm.
