4-track machine arrives

The sneak peek came a year ago at the John Deere rollout of the new 9R/9RT lineup — a four-track machine dubbed the 9RX. Many assumed the X stood for experimental, yet as farmers hit the John Deere exhibit at the fall farm shows they’ll see there is nothing experimental about this new four-track machine.

The sneak peek came a year ago at the John Deere rollout of the new 9R/9RT lineup — a four-track machine dubbed the 9RX. Many assumed the X stood for experimental, yet as farmers hit the John Deere exhibit at the fall farm shows they’ll see there is nothing experimental about this new four-track machine.

The 9RX line includes four models: 9470RX, 9520RX, 9570RX and 9620RX, with the model number denoting engine horsepower. There are three scraper special models: 9470RX, 9520RX and 9570RX. Jerry Griffith,division marketing manager, high-horsepower tractors, says, “We took what we learned about the way we tension our belt systems, our alignment and our mid-roller technologies with our 8RT and 9RT and developed our four-track tractor.” The key, he says, is an undercarriage design that is “very robust and delivers maximum uptime and a low cost of operation.”

Griffith says buyers will see a taller undercarriage compared to competitors with a larger drive sprocket — 39.5 inches in diameter — and more wrap angle for more positive drive lug engagement. “The belt is 20% longer and the advantage of that is that to travel the same distance as a competitor, our belt will travel 20% less,” he says. “That will equate to 20% longer wear life.”

The 9470RX and 9520RX uses a John Deere PowerTech PSS 13.5-liter engines. The larger 9570RX and 9620RX have Cummins QSX15 engines. An enhanced CommandView III Cab is with the 9 series tractors. The enhancement is a suspended cab. It’s the first suspended cab for the series. The cab has spring-loaded shocks on each corner and a Parallel Plane Four Bar Linkage to control cab movement and isolate the cab and operator from impacts.

Griffith says the new tractor will have a lot of the same benefits as its siblings, the 9R and 9RT, including the e18 Powershift Transmission with Efficiency Manager for fuel management. The CommandView III Cab operating environment includes the 10-inch CommandCenter display that’s easy to navigate and customize.

There’s also the option of adding Active Command Steering, which in these drive-by-wire machines manages the steering through software to make control easier and more precise.

The redesigned hydraulic system available on the 9R/9RT Series is offered on the 9RX too. This system delivers an industry-leading high-flow hydraulics option, providing 115 gallons per minute of flow and up to eight rear SCVs for implements with high hydraulic demands.

Griffith adds that this tractor is John Deere FarmSight ready to work with all the components and technology designed for the MyJohnDeere system, which allows farmers to collect and share information about any task being accomplished on the farm. “We have the Green on Green integrated technologies like John Deere Ag Management Systems precision farming equipment. Our integration with our new technologies on our tillage system, for example, allows you to set depth control from the cab,” Griffith says.
