Introduction

Caterpillar Forty Agricultural Crawler

The Caterpillar Forty is a vintage agricultural crawler tractor produced between 1934 and 1936 in Peoria, Illinois, USA. Designed for heavy-duty traction, this machine represents the industrial engineering standards of its era.

Engine and Performance

The tractor is powered by a liquid-cooled, 4-cylinder gasoline engine with a displacement of 485.3 cubic inches (8.0 liters). It operates at a rated speed of 850 RPM, providing a power output of 54 hp. The bore and stroke dimensions are 5.125 by 6.50 inches, characterizing the robust design required for sustained agricultural work.

Transmission and Drive System

The mechanical configuration features a gear-type transmission offering four forward speeds and one reverse gear. As a crawler tractor, it utilizes a tracked drive system, which provides superior flotation and traction compared to wheeled tractors, particularly on soft or uneven ground.

Dimensions and Construction

The machine has an operating weight of 13,625 lbs (6,180 kg). It is equipped with 16-inch wide tracks to distribute its weight effectively. The operator station is of the open type, which was standard for the period, providing the operator with direct access to controls and visibility of the work area.

Conclusion

"With its significant weight and tracked propulsion, the Caterpillar Forty was engineered for demanding agricultural tasks requiring high pulling power and stability. It remains a historical reference for mid-1930s heavy machinery design."
