Introduction

Graham-Bradley 103: Row-Crop Tractor

The Graham-Bradley 103 is a vintage row-crop tractor produced between 1938 and 1939 in Detroit, Michigan, USA. Designed for agricultural operations during this period, the machine is characterized by its 33-horsepower engine and two-wheel drive configuration.

Engine and Powertrain

The tractor is powered by a 6-cylinder gasoline engine with a displacement of 218 cubic inches (3.6 liters). It utilizes a liquid cooling system to maintain operating temperatures and features a Schebler carburetor for fuel management. Air intake is filtered through an oil bath system. The engine is rated at 1500 RPM, with a firing order of 1-5-3-6-2-4 and a bore/stroke ratio of 3.25 by 4.375 inches.

Transmission and Mechanical Layout

Power is delivered through a gear-type transmission providing 4 forward gears and 1 reverse gear. The drivetrain incorporates a dry disc clutch. The tractor utilizes a two-wheel drive system, controlled via manual steering. The operator station is of the open-type design, consistent with tractors of that era.

Tires and Dimensions

To accommodate row-crop applications, the tractor is equipped with specific agricultural tire sizing. The front tires are sized 5.50x16, while the rear tires feature a 9.00x36 configuration, providing the necessary traction for field tasks.

Conclusion

"The Graham-Bradley 103 serves as a representative example of late 1930s row-crop machinery. Its mechanical simplicity, combined with a standard 6-cylinder gasoline engine, makes it a notable piece for collectors of vintage American agricultural equipment."
