Introduction
Caterpillar AG6 Agricultural Crawler Tractor
The Caterpillar AG6 is a heavy-duty agricultural crawler tractor produced between 1986 and 1993. Based on the mechanical architecture of the Caterpillar D6, this machine was primarily marketed in the western United States for demanding field operations, serving as a steel-tracked alternative before the industry transition toward rubber-tracked configurations.
Engine and Powertrain
The tractor is powered by the Caterpillar 3306, a 10.5-liter, 6-cylinder turbocharged and aftercooled diesel engine. It produces 240 hp at a rated speed of 2200 RPM. The drivetrain utilizes a sliding gear transmission providing 6 forward and 6 reverse speeds, managed through a wet disc clutch system to handle high torque requirements.
Hydraulic System
Equipped with a closed-center, load-sensing hydraulic system, the AG6 is designed for efficiency and responsiveness. The system delivers a pump flow of 26.4 gpm (99.9 lpm) at a working pressure of 2350 psi. It features 5 valves, allowing for the operation of various hydraulic implements required in agricultural tasks.
Chassis and Operator Environment
The AG6 features a crawler drive configuration with 24-inch tracks, contributing to its total operating weight of 32,600 lbs. Steering is facilitated by hydraulic wet disc clutches, supported by wet hydraulic band brakes. The standard factory cab includes air-conditioning to maintain operator comfort during long field cycles.
Conclusion
The Caterpillar AG6 represents a specialized segment of 1980s agricultural machinery. Its robust design and high drawbar capacity make it suitable for intensive tillage and heavy-duty pulling operations where traditional wheeled tractors may lack sufficient traction.
