Introduction
John Deere 4490 Agricultural Tractor
The John Deere 4490 is a row-crop tractor produced between 1985 and 1986. Manufactured by Chamberlain in Welshpool, Australia, under the John Deere brand, this model was designed to provide reliable power and operational flexibility for diverse field applications.
Engine and Performance
The tractor is powered by a 7.6-liter, 6-cylinder turbocharged diesel engine. It generates a net power output of 137 hp (102.2 kW) at a rated speed of 2200 RPM. The engine cooling system features a capacity of 24.2 liters, and it utilizes a dry-type air cleaner with a safety element to ensure longevity under dusty conditions.
Transmission and Drivetrain
The 4490 utilizes a partial power shift transmission, providing 12 forward and 4 reverse gears. The system features a hydraulic Hi-Lo power shift mechanism, allowing for on-the-fly range adjustments. Gear selection is managed through three gears across two ranges, with range shifts synchronized via a 15.5-inch dry disc clutch. While standard models come in a 4x2 2WD configuration, a 4x4 MFWD option was available to improve traction.
Hydraulics and Hitch
The hydraulic system is an open-center type, delivering a total flow of 15.6 gpm (59.0 lpm) at a maximum pressure of 2500 psi (172.4 bar). The tractor is equipped with a Category III/IIIN rear hitch featuring top-link sensing, capable of lifting up to 2,956 kg at 24 inches behind the lift point, with an optional higher capacity hitch available.
Operator Environment and Dimensions
The tractor features a standard cab equipped with air-conditioning to support operator comfort during extended field operations. Steering is handled by a hydrostatic power system, and braking is provided by hydraulic wet disc brakes. The 2WD model weighs approximately 13,779 lbs, while the 4WD variant has a shipping weight of 14,319 lbs.
Conclusion
The John Deere 4490 is a robust, mid-range row-crop tractor that combines proven John Deere engineering with specialized manufacturing. Its combination of a powerful 6-cylinder engine, partial power shift transmission, and versatile hydraulic capacity makes it a suitable machine for heavy-duty agricultural labor and general field tasks.
