John Deere 9RX 640 – From 640 HP to 710 HP. Safely. Precisely. Software Only.

This tractor was already a powerhouse. But after a precise software reprogramming by AgroEcoPower, the John Deere 9RX 640 now delivers an impressive 70 horsepower increase – reaching a total of 710 HP, all without any mechanical modifications.

What we optimized:

• Injection timing and duration
• Fuel quantity and air-to-fuel ratio
• Turbo boost pressure
• Throttle response and torque map calibration

The result:

• Significantly improved pulling power
• Better efficiency under load
• Same reliability – with much more power

All of this was done safely, with no mechanical changes. Just a clean software upgrade, fully tailored to the engine’s specifications and limits.
