John Deere 9RX 590 Extra Horsepower Notes
Horsepower note
The John Deere 9RX 590 shows 639.7 hp at the engine and 335 hp at the PTO, which is a large gap between engine power and PTO power for a high-horsepower tractor.
PTO note
With 335 hp at the PTO, the John Deere 9RX 590 is best matched to large PTO-driven equipment where the implement horsepower requirement matters more than the engine rating; large implements still need to be matched by PTO requirement, ballast, traction and transmission setup.
Drawbar note
At 582 hp drawbar power, the John Deere 9RX 590 is about 57.7 hp below its engine rating once power is measured as pull at the ground.
Power-to-weight note
The John Deere 9RX 590’s weight-to-power figure is about 88 lb per engine horsepower; that means it is light for its power, so traction and ballast can become the limiting factor before engine power.
Engine note
The John Deere 9RX 590’s 13.6 L engine makes 639.7 hp, or about 47 hp per litre.
Torque / RPM note
The John Deere 9RX 590 combines 2,008 lb-ft of torque with a 2,100 rpm rated engine speed, which fits a lower-speed tractor engine setup.
Official information note
Mistakes do happen. Horsepower, PTO horsepower, drawbar horsepower, weight and engine specs can change by year, market, engine option, cab, transmission and test standard. Please check the operator manual and official deere.com website for official information.
