The International Harvester 15-30 is a standard-tread tractor produced between 1917 and 1921 as part of the Titan series. Designed for agricultural operations, this machine represents a significant phase in early 20th-century tractor engineering, with 6,024 units manufactured across facilities in Chicago, Illinois, and Milwaukee, Wisconsin.

Engine and Performance

The tractor is powered by a liquid-cooled, 4-cylinder horizontal valve-in-head engine with a displacement of 692.7 cubic inches (11.4 L). It operates on kerosene and is designed for a rated speed of 575 RPM. The engine features a bore and stroke of 133 x 203 mm, providing a power output of 33 hp, suitable for the traction requirements of the era.

Transmission and Drivetrain

The 15-30 utilizes a gear-based transmission system consisting of two forward gears and one reverse gear. It is configured as a two-wheel-drive tractor, relying on its mechanical simplicity to deliver power to the rear steel wheels.

Dimensions and Construction

With a total weight of 8,990 lbs (4,077 kg), the tractor is built for stability during heavy field work. It measures 140.5 inches (356 cm) in length, 85 inches (215 cm) in width, and 118 inches (299 cm) in height. The machine is equipped with steel tires, measuring 40x7 inches at the front and 66x14 inches at the rear. The cooling system has a large capacity of 160 quarts (151.4 L).

Operator Environment

The operator station is an open design, intended for basic field operation. A four-post canopy was available as an optional feature to provide protection from the elements for the operator.
