Introduction
Gibson D: A Compact Utility Tractor (1947-1949)
The Gibson D is a compact tractor produced between 1947 and 1949 in Longmont, Colorado, USA. Designed for light-duty agricultural operations, this machine represents the post-war era of small-scale mechanical farming equipment.
Engine and Performance
The tractor is powered by a Wisconsin AEH air-cooled, single-cylinder gasoline engine. It features a displacement of 23 cubic inches (0.4 L) with a bore and stroke of 3.00 by 3.25 inches. The engine produces 6 horsepower (4.5 kW) at a rated speed of 2000 RPM. To ensure longevity in dusty field conditions, the engine is equipped with an oil bath air cleaner.
Transmission and Drivetrain
The Gibson D utilizes a two-wheel drive system managed by an unsynchronized gear transmission. This setup provides three forward gears and one reverse gear. Power delivery to the transmission is controlled via an idler pulley clutch, a typical configuration for tractors of this class and period.
Mechanical and Dimensions
The tractor features an open operator station and is operated via a manual tiller steering system. With a wheelbase of 46 inches (116 cm) and a total height of 45 inches (114 cm), the machine maintains a compact profile. The total weight is 955 lbs (433 kg). It is fitted with 4.00x12 agricultural front tires and 7.00-24 agricultural rear tires to provide necessary traction for light implement work, such as pulling a single plow.
Conclusion
The Gibson D serves as a specialized, lightweight tractor suitable for small-scale cultivation and gardening tasks. Its simple mechanical design and maneuverability make it a notable example of American-built utility machinery from the late 1940s.
