In August 2015, John Deere announced its newest tractor model, the high-horsepower 9RX tractor. It is the first four-track tractor that the company has manufactured.
The 9RX comes in four models ranging from the 470-horsepower 9470RX to the 9620RX with 620 horsepower. Cummins produces the air-to-air aspirated QSX15 engine available in models 9570RX and 9620RX, which meets Final Tier 4 emission standards. Dual hydraulic pumps provide 115 gallons per minute at low engine rates. The 9RX series also features John Deere’s CommandView III cab with sound-reducing laminated glass and console barrier. Each model is AutoTrac- and JDLink-capable with account activation and subscription.
