Introduction

Rock Island F 18-35 standard-tread tractor

The Rock Island F 18-35 is a standard-tread agricultural tractor manufactured between 1927 and 1937 in Rock Island, Illinois, USA. It represents a period of mechanical development in early 20th-century farming, characterized by robust construction and simplicity of operation.

Engine and Performance

The tractor is powered by a 4-cylinder Buda L-head engine with a displacement of 382 cubic inches (6.3 L). Designed to operate on kerosene, the engine features liquid cooling and a bore/stroke ratio of 114 x 152 mm. It produces 38 horsepower at a rated engine speed of 1100 RPM, providing steady power for traction tasks common to its era.

Transmission and Drivetrain

The drivetrain utilizes a two-wheel drive configuration. Power is delivered through an unsynchronized gear transmission, which provides two forward gears and one reverse gear. This manual transmission system requires the operator to manage gear changes without the assistance of modern synchronizers, reflecting the technical standards of its production period.

Operator Environment and Steering

The machine features a manual steering system and an open operator station. This design provides the operator with unobstructed visibility of the surroundings and the implement being towed, which is essential for standard agricultural field operations.

Conclusion

The Rock Island F 18-35 is a representative example of 1920s and 1930s American tractor manufacturing. Due to its historical nature and mechanical design, it is primarily suited for agricultural history enthusiasts and collectors interested in vintage machinery preservation.
