The newest John Deere and Claas tractors are now open to KESS3. Upgrade 3.60 lets you read and write Phoenix L33M ECUs over OBD on models built from 2025 on.
You work through the tractor's diagnostic port with no physical work on the control unit. That keeps jobs quick and practical, even out in the field, and keeps downtime to a minimum.
