A little more perspective
John Deere’s 9 Series brochure lists the 9RX 640 reference at 3,946 millimeters high, measured to the top of the exhaust. The illustrated configuration uses four track units, front ballast, and no attached implement. The listed endpoint is above the cab roof, not a measurement to an optional antenna.
The same brochure distinguishes the 9RX’s four track units from the two-track 9RT and wheeled 9R models. The exhaust-top marker applies to this selected 9RX configuration. Track width changes its footprint, while attached equipment or tall optional antennas can create a different overall envelope.
