The 9RX Series Tractors deliver the proven reliability of John Deere’s 20 years of experience in the rubber-tracked tractor business. The 9RX Series will be available in four models from 420 hp to 620 horsepower. These models are powered by the John Deere PowerTech™ PSS 13.5-L, and the Cummins® QSX15 engines.

It’s no secret that John Deere has been developing a high-horsepower tractor with four tracks. Last August at the company’s dealer meeting, a prototype dubbed the 9RX, sporting four-wide tracks, was rolled out to thundering applause. Dealers and customers wondered how long it would be until the new technology was available.

The wait is officially over. John Deere will start offering the 9RX for model year 2016

The potential of any tracked tractor lies within the undercarriage system. Using a sealed cartridge mid-roller design proven on John Deere two-track tractors, the 9RX undercarriage features a large-diameter 39.5-inch drive sprocket, optimally placed idlers and mid-rollers, and a field-tested track tensioning and alignment system.

“When we designed the undercarriage, we wanted good reliability and ease of maintenance,” explains Griffith. “Around reliability, one of the first things you notice is the taller undercarriage and larger components used compared with competitors'. One of the main benefits of a larger undercarriage is that the belt is 20% longer, which should provide 20% longer life.”
