Introduction
Caterpillar D4E SA Crawler Tractor
The Caterpillar D4E SA is a dedicated agricultural crawler tractor produced between 1984 and 1991. Designed for demanding field operations, it serves as a specialized machine for heavy-duty traction and cultivation tasks where soil compaction must be minimized and pulling power maximized.
Engine and Performance
The tractor is powered by the Caterpillar 3304, a liquid-cooled, inline 4-cylinder turbocharged diesel engine. It features a displacement of 7.0 liters and direct fuel injection, delivering a net power output of 97 hp (72.3 kW) at a rated speed of 2000 RPM. This engine configuration is engineered for high torque output required for sustained agricultural work.
Transmission and Drive
The D4E SA utilizes a gear-type transmission providing 5 forward and 5 reverse speeds, allowing the operator to select the appropriate gear ratio for varying soil conditions and implement requirements. The crawler drive system, equipped with 16-inch tracks, ensures optimal weight distribution and traction, contributing to the tractor's operating weight of 18,450 to 19,050 pounds.
Hydraulics and Electrical Systems
The hydraulic system is an open-center design with a pump flow capacity of 21.6 gpm (81.8 lpm) and an operating pressure of 1200 psi (82.7 bar), providing the necessary force to actuate heavy implements. The electrical system operates on a 12-volt battery configuration supported by a 35-amp alternator to maintain consistent power for engine starting and auxiliary functions.
Conclusion
The Caterpillar D4E SA is a robust, specialized tool built for agricultural professionals requiring high traction and consistent performance. Its combination of a high-torque diesel engine, mechanical transmission, and stable crawler base makes it suited for intensive tillage and heavy draft applications.
