Introduction
Challenger 85C Agricultural Crawler Tractor
The Challenger 85C is an agricultural crawler tractor manufactured by Challenger, a division of Caterpillar, in Peoria, Illinois, USA. Produced between 1994 and 1996, this machine was designed for heavy-duty field operations, utilizing a tracked drive system to optimize traction and minimize soil compaction.
Engine and Performance
The tractor is powered by a liquid-cooled, 6-cylinder turbocharged and intercooled diesel engine. With a displacement of 10.3 liters (629 cubic inches), the engine generates 355 hp at a rated speed of 2100 RPM. It features a compression ratio of 16:1 and utilizes dual dry element air cleaners. Cold weather starting is supported by ether injection and an engine block heater.
Transmission and Drive
The 85C utilizes a full power shift transmission providing 10 forward gears and 2 reverse gears, allowing for on-the-go shifting without the use of a clutch. The crawler drive system is supported by 30-inch tracks, contributing to the machine's total weight of 33,645 lbs (15,261 kg) and a wheelbase of 107.1 inches.
Hydraulics and Steering
The tractor is equipped with a closed-center hydraulic system with a pump flow of 27 gpm and an optional 35 gpm capacity, supporting 4 valves for implement operation. The steering system operates at a pressure of 6090 psi with a flow rate of 61.4 gpm. Maneuverability is assisted by power steering, while stopping is managed by hydraulic wet disc brakes.
Electrical System
The electrical system is based on a 12-volt architecture with a negative ground configuration. Power is supplied by two batteries providing 900 CCA. The system uses an alternator for charging, with a capacity of 115 amps.
Conclusion
The Challenger 85C is a specialized high-horsepower crawler tractor engineered for large-scale agricultural tasks requiring significant tractive effort and stability. Its robust chassis, combined with a high-capacity hydraulic system and power shift transmission, makes it a reliable choice for heavy tillage and primary cultivation work.
