John Deere: New four-track 9RX Series tractors unveiled

By WniF editors

John Deere has introduced its first-ever four-track tractor, adding to its extensive range of high horsepower 9R Series wheeled and 9RT Series two-track tractors. The four new 9RX tractor models – which range from 470hp to 620hp – feature a large, robust undercarriage and track system engineered to provide superior power, durability and improved ride quality, especially when handling large implements in the field.

The 9RX undercarriage features a positive-drive track system that effectively delivers more power to the ground. This is ideal for heavy draft applications such as cultivating, ploughing, discing and ripping, subsoiling and large-scale drilling applications.

The new 9470RX and 9520RX tractors are powered by 13.5-litre John Deere PowerTech PSS engines, whereas the 9570RX and 9620RX use 15-litre Cummins QSX engines. Featuring cooled exhaust gas recirculation, enhanced turbocharger technology, diesel particulate filter and selective catalytic reduction technology, both engine makes are compliant with Stage IV emissions regulations, and are designed to provide the torque and power to handle the toughest field conditions.

Deere’s new 9RX tractor models range from 470hp to 620hp.

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. The new 9RX tractors are equipped with rugged, puncture-resistant Camso Durabuilt 3500 and 6500 Series belts with Duradrive Technology for peak load-bearing performance in the field. The 76cm wide track belts are designed for increased durability and remain within the overall machine width limit of 3m. Extra-wide 91cm tracks are optionally available.

Like its 9R and 9RT siblings, the new four-track 9RX tractors are available with the responsive, smooth-shifting e18 transmission with Efficiency Manager for automated control of the engine and transmission. This industry-leading transmission responds quickly and automatically in the field for improved performance and increased fuel savings. The new tractors also feature an articulated steering system and optional Active Command Steering (ACS), which improves manoeuvrability in the field and line-holding ability, even at transport speeds of up to 40km/hr.

The 9RX CommandView III cab features a new cab suspension system, which significantly improves the tractors’ ride quality by allowing up to 10cm of vertical travel. This helps to control movement and isolates the cab and operator from sudden impacts and vibration.

Deere’s 9RX tractors are the company’s first four-track models.

Other ergonomic cab features include the fully integrated AutoTrac guidance and JDLink Connect information management systems, and the intuitive, easy-to-use Generation 4 CommandCenter display with custom-designed pages to provide fingertip control of tractor and implement functions. For optimum visibility even at dusk or night-time, as many as 24 LED lights spread daytime-quality light around both the tractor and implement.

In addition, to meet the speed and high hydraulic power demands of large implements, the hydraulic system has been redesigned and now includes up to eight SCVs delivering a standard flow of 220 lit/min, or an optional 435 lit/min.
