Introduction
John Deere 9RX 490 Articulated Crawler Tractor
The John Deere 9RX 490 is a high-horsepower articulated crawler tractor designed for large-scale agricultural operations. Part of the 9RX series produced at the Waterloo, Iowa facility, this machine integrates advanced power management with a four-track system to maximize traction and reduce soil compaction in demanding field conditions.
Engine and Performance
The tractor is powered by the John Deere JD14, a 13.6-liter, 6-cylinder turbocharged and aftercooled diesel engine. It delivers a rated power of 482.8 hp (360.0 kW) and a maximum gross power of 531 hp (396.0 kW). The engine features an electronic high-pressure common rail fuel system and operates at a rated speed of 2100 RPM, producing a torque of 1668 lb-ft at 1550 RPM.
Transmission and Drive
Equipped with the e18 full power shift transmission, the 9RX 490 offers 18 forward and 6 reverse gears, allowing for precise speed control during heavy draft applications. The drive system consists of an articulated-crawler configuration utilizing 18-inch tracks, supported by electro-hydraulic front and rear differential locks for enhanced maneuverability and grip.
Hydraulics and Hitch
The hydraulic system is a closed-center, pressure-flow compensated type. It provides a standard pump flow of 55 gpm (208.2 lpm), with optional configurations reaching up to 110 gpm (416.4 lpm). The system operates at a pressure of 2900 psi and supports 4 to 8 SCVs. The rear hitch is a Category IVN/IV type with a lift capacity of 15,000 lbs (6,804 kg) measured at 24 inches behind the lift point.
Operator Environment and Dimensions
The tractor features a standard cab equipped with air-conditioning to maintain operator comfort during extended field operations. With a wheelbase of 162.5 inches and a total operating weight of 56,320 lbs (25,546 kg), the machine provides the necessary stability for heavy-duty tillage and planting tasks.
Conclusion
The John Deere 9RX 490 is engineered for professional agricultural producers requiring high-capacity performance and reliable traction. Its combination of a high-torque 13.6L engine, robust powershift transmission, and flexible track-based drive system makes it suited for intensive large-acreage farming and heavy pulling requirements.
