Introduction
Challenger 85D Agricultural Crawler Tractor
The Challenger 85D is a heavy-duty agricultural crawler tractor manufactured by Challenger, a division of Caterpillar, produced between 1996 and 1997. Designed for large-scale farming operations, this machine focuses on high-traction performance and significant draft capabilities.
Engine and Performance
The tractor is powered by a 6-cylinder, 11.9-liter (729 ci) turbocharged and intercooled diesel engine. It delivers a gross power output of 370 hp (275.9 kW) at a rated engine speed of 2100 RPM. The engine cooling system has a capacity of 80 quarts (75.7 L), and the system incorporates ether injection to facilitate cold-weather starting.
Transmission and Steering
Power is delivered through a full power shift transmission, providing 10 forward gears and 2 reverse gears. Steering is achieved via a hydrostatic differential system, which allows for precise control of the crawler tracks. Braking is handled by hydraulic wet disc brakes.
Hydraulics and PTO
The hydraulic system is a closed-center, pressure-compensated design operating at 2750 psi (189.6 bar). It provides a standard pump flow of 27 gpm (102.2 lpm), with an optional capacity of 35 gpm (132.5 lpm). The tractor features four valves for implement control. An optional independent rear PTO is available, providing 1000 RPM at 2050 engine RPM using a 1.75-inch shaft.
Dimensions and Undercarriage
The 85D utilizes a crawler drive system with 25-inch wide tracks, contributing to its weight of 34,234 lbs (15,528 kg). The machine features a wheelbase of 107 inches (271 cm), designed to distribute weight effectively for maximum traction on field surfaces.
Conclusion
The Challenger 85D is engineered for intensive field tasks, such as deep tillage and heavy-duty pulling, where high traction and consistent power delivery are required. Its standard air-conditioned cab and robust mechanical layout reflect its position as a high-capacity tool for professional agricultural environments.
