Introduction
John Deere 9R 440: Articulated 4WD Tractor
The John Deere 9R 440 is a high-horsepower, articulated four-wheel-drive tractor designed for large-scale agricultural operations. Introduced as part of the 9R series, this model represents a heavy-duty platform engineered for demanding traction and field tasks.
Engine and Powertrain
The tractor is powered by a 13.6-liter, 6-cylinder, 24-valve liquid-cooled diesel engine. It features a turbocharged and aftercooled induction system combined with an electronic high-pressure common rail fuel system. The engine delivers a rated power of 434.5 hp (324.0 kW) at 2100 RPM, with a maximum gross power output of 477.4 hp (356.0 kW). A 12-volt electric starter system and a dry air cleaner are standard.
Transmission and Drivetrain
The 9R 440 utilizes the e18 full power shift transmission, providing 18 forward and 6 reverse gears to accommodate various field speeds. The drivetrain features permanent four-wheel drive with articulated power steering. Final drives are of the inboard planetary type, and the machine is equipped with hydraulic wet disc brakes and electro-hydraulic differential locks on both the front and rear axles.
Hydraulics and Hitch
The hydraulic system is a closed-center, pressure and flow-compensated design. 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 supports between 4 and 8 selective control valves (SCVs). The rear hitch is a Category IVN/IV setup with a lift capacity of 15,000 lbs (6,804 kg) measured at 24 inches behind the lift point.
Dimensions and Weight
The tractor has a wheelbase of 154 inches (391 cm) and an overall length of 312.8 inches (794 cm). The minimum width over tires is 173.3 inches (440 cm). The shipping weight is approximately 45,980 lbs (20,856 kg), with a maximum allowable weight of 62,000 lbs (28,123 kg), allowing for significant ballast to maximize traction.
Conclusion
The John Deere 9R 440 is purpose-built for heavy-duty primary tillage and large-acreage operations. Its robust engine, flexible transmission, and high-capacity hydraulic system make it suitable for farmers and agricultural contractors requiring sustained power for demanding implements.
