The long wait for official information is over. John Deere released details and pictures of its eagerly-awaited 9RX Series four-track tractors today via a webcast. It’s innovation, not imitation is how the new four-model range is promoted. And it’s no copycat either is the message, the result being a game-changing 4-track tractor that’s described as anything but ordinary. Aimed to compete with the Case IH Quadtrac, the 9RX spans 470-620hp. The four models are the 9470 (470hp), 9520 (520hp), 9570 (570hp) and 9620 (620hp). Official information on John Deere’s website confirms power to the two ‘smaller’ models comes courtesy of a 13.5-litre Stage IV John Deere PowerTech engine. However, the company has partnered with Cummins to offer the QSX 15 (15-litres/Stage IV) as an option. This engine is fitted as standard in the two top models. All four tractors have an e18 Powershift transmission, a new cab suspension system, AutoTrac and JDLink, and it goes without saying that the 9RX is designed with a robust drivetrain and undercarriage. Just how robust? Well, the claim is the upswept axle component is the largest cast part poured in the nation. Other than the fact they are claimed to provide agile performance and better flotation and grip in wet or loose soil conditions, there is not a lot of information on the tracks. However, there is quite a lot of information on the rest of the tractor plus a couple of short videos on If you want to see the machine in the flesh then make sure you visit Agritechnica.
