Ag-equipment giant John Deere has unveiled its first quad track tractor range, the 9RX after years of design, field trials and customer feedback.

Adding to its existing high-horsepower line up consisting of the 9R series wheeled and 9RT series two-track tractors, the new 9RX range offers four models ranging from 470 to 620 hp.

They feature a large, robust undercarriage and track system John Deere says have been engineered to provide superior power, durability and improved ride quality especially when handling large implements in the field.

John Deere 6-9 Family tractors product marketing manager Jerry Griffith says the new 9RX four-track tractors offer customers three distinct advantages compared to other similar models on the market.

"The 9RX has a superior undercarriage with a positive-drive track system that effectively delivers power to the ground; it features the outstanding comfort of our CommandView III cab with a new cab suspension system for improved ride quality; and it is designed with integrated performance features already available on our 9 family of tractors," he says.

According to John Deere, the machines’ rubber tracks; supplied by tires and tracks specialist Camso are puncture-resistant and allow for optimal load-bearing on the field.

The company adds the track belts are designed for increased life and durability and are available in 30-inch (762mm) and 36-inch (914mm) widths.

Powering the new series is the John Deere PowerTech PSS 13.5-litre engine for the 9470RX and 9520RX models; and the Cummins QSX15 engine for the 9570RX and 9620RX models.

John Deere says the engines power a large diameter drive sprocket and drive lugs that, along with optimally placed idlers and mid-rollers, work to deliver exceptional horsepower to the ground with less track slippage.

Like its 9R and 9RT siblings, the new 9RX tractors come with the e18 transmission with Efficiency Manager for automated control of the engine and transmission. John Deere adds the industry-leading transmission is capable of responding quickly and automatically in the field for improved performance and increased fuel savings.

"We’ve also redesigned the hydraulic system in the new 9RX, which includes up to eight SCVs and delivers a standard 220-litres per minute of flow, or an optional 435-litres per minute of flow," Griffith says.

"It easily meets the speed and high hydraulic power demands of the large implements our customers often use in the field."

The range also features an articulated steering system and the optional Active Command steering system which improves manoeuvrability in the field and in-line holding ability at transport speeds.

For improved ride quality, a mechanical parallel plane four-bar linkage system with 10cm of vertical travel has been installed on the 9RX tractors. John Deere says the system helps to control movement and isolates the cab and operator from sudden impacts and vibration.

Other features on the 9RX series include built-in, fully integrated AutoTrac guidance and JDLink Connect information management systems; and a Generation 4 CommandCenter control system for fingertip control of tractor and implement functions.

"The 9RX brings to the market John Deere’s 20 years of track-tractor expertise and field knowledge gained from our popular 8RT and 9RT tractors," Griffith says.

"Customers tell us the 9RX has the most comfortable ride, is easier to manoeuvre in the field, is easier to maintain and service, and more importantly, provides the power they need to get field work done faster and more effectively."

Orders for the 9RX series will open on October 1 with the first shipment of tractors expected to arrive in Australia in mid-2016.
