Technology, Connectivity, and Automation

Engineered for performance, technology features include an integrated precision ag platform with AutoTrac™ guidance readiness, JDLink™ connectivity, and access to John Deere Operations Center™. Advanced automation and data tools can help improve efficiency, uptime, and in-field productivity.

JDLink™ hardware comes standard with the machine. You can turn on JDLink connected service in your John Deere Operations Center™ account for free. JDLink requires a cellular connection to transfer information from machine to Operations Center. Consult your John Deere Dealer for coverage availability.
