John Deere 9RX – the range of articulated four-track big tractors from the 9RX 490 to the 9RX 830, a six-cylinder engine of 13,548 to 17,940 cm³, 436.9 to 672 kW, up to 33,110 kg unladen weight
The John Deere 9RX is the range of four-track big tractors built in Waterloo, Iowa, the traditional home of John Deere's large field tractors; the range spans the 9RX 490, 540, 590, 640, 710, 770 and 830, whose number denotes the approximate power class in horsepower. Unlike the articulated wheeled tractors of the 9R range, the 9RX stands on four separate rubber-track undercarriages instead of wheels, which increases the contact area and lowers ground pressure compared with wheeled tractors of the same output.

The register lists here 7 versions with 436.9 to 672 kW from six-cylinder engines of 13,548 to 17,940 cm³, unladen weights from 26,114 to 33,110 kg, gross vehicle weights from 32,000 to 42,185 kg, lengths from 8,705 to 8,829 mm and widths from 2,980 to 2,997 mm.
With over 600 kW at the top of the range, the 9RX is among the most powerful field tractors of all and is built for cultivating the extensive fields with wide cultivators and tillage combinations typical above all of the North American Great Plains, where the four-track layout limits soil compaction on large, intensively farmed areas.
On used examples, the condition of the four track undercarriages with rollers, track links and the tensioner, the operating hours and service history of the six-cylinder engine, and the hydraulic and electronic systems all matter; given the size and technical complexity, service and spare parts run practically exclusively through authorised John Deere dealers.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
