Introduction
Gibson H Row-Crop Tractor
The Gibson H is a row-crop tractor produced between 1948 and 1952 in Longmont, Colorado, USA. Designed for agricultural operations, this machine represents the post-war era of American tractor manufacturing, delivering 27 horsepower through a two-wheel-drive configuration.
Engine and Performance
The tractor is powered by a Hercules IXB3 four-cylinder gasoline engine with a displacement of 133 cubic inches (2.2 liters). It features liquid cooling and an oil bath air cleaner to maintain operational efficiency. The engine reaches its power output at a rated speed of 1800 RPM, utilizing a 6-volt electrical system for starting.
Transmission and Drivetrain
Power is transferred to the wheels via a gear-type transmission providing 4 forward speeds and 1 reverse speed. The drivetrain includes a 254mm dry disc clutch and utilizes bull gear final drives. Control is managed through manual steering and mechanical band brakes, ensuring reliable operation in field conditions.
Hydraulics and PTO
The Gibson H is equipped with a live rear power take-off (PTO) operating at a standard 540 RPM. This allows the operator to maintain implement power independently of the tractor's forward motion, which is essential for various row-crop tasks.
Dimensions and Chassis
Built on an 86-inch wheelbase with a ground clearance of 25 inches, the tractor is designed for maneuvering through crop rows. The rear tread width is adjustable between 47 and 85 inches to accommodate different row spacings. It typically runs on 5.00-15 front tires and various rear tire options, including 10-38, 11-38, or 12-38 sizes.
Conclusion
The Gibson H is a straightforward, mechanical row-crop tractor suited for small to medium-scale agricultural tasks. Its simple design and standard PTO configuration make it a functional choice for collectors and users interested in post-1945 American utility tractors.
