Last month a few members of our marine team travelled out of state to install John Deere Connected Support hardware on a commercial fishing operation consisting of one large vessel and two smaller boats.

The larger vessel utilized five John Deere 6068 auxiliary engines to run pumps, gear, and refrigeration systems, while each smaller boat is powered by a John Deere 6068 propulsion engine.

Connected Support gives access to valuable engine and operational data including engine hours, operating history, location tracking, and geofencing alerts. Additionally predictive maintenance notifications are given to help make informed decisions while reducing unplanned downtime.

For fleet operators, the benefits are even greater. Instead of traveling to a vessel to retrieve engine data, key information can be accessed remotely, helping save time, reduce service costs, and improve fleet efficiency. Get Connected Support standard on new 6068 through JD18 engines at no additional cost. Retrofit options are also available to bring the same benefits to 4045 and existing engines.

This fleet as well as many others are investing in technology to support future fleet growth, including larger offshore vessels powered by John Deere 6090 engines. Connected Support was an important part of demonstrating how modern engine technology and remote connectivity can support their growing operations.

Great teamwork by everyone involved and another example of how we're helping customers stay connected, maximize uptime, and get more from their equipment.

Superior Diesel's service department was contacted by an OEM customer, on behalf of an end user who recently purchased a woodchipper and was experiencing issues with "regen". More specifically, a lack of passive regeneration of the aftertreatment. Our service department worked with the end user to troubleshoot his codes/issues over the phone. After exhausting the troubleshooting that the end user was comfortable with, the decision was made to involve his local John Deere servicing dealer.

The servicing dealer determined the engine was not going through passive regen due to the way the engine/machine had been operated. When the customer received a bill for the service level regen performed at the dealer they involved us as their OEM distributor service support. We contacted the dealer, but they had not retained the ECU regen abort load profile, so the customer had to bring the machine back to the dealer for a quick scan of the ECU. The reports revealed an issue with the engine's ability to reach operating temperature.

Through these reports we determined this machine needed to be monitored through John Deere Operations Center. Working with the OEM and the end-user, we supplied a JDLink (Connected Support) modem that the OEM was able to install. Once installed, our service team began to remotely monitor the engine through John Deere Operations Center. While remotely monitoring we again saw the engine was unable to reach proper operating temperature. Going a step further, we contacted the end user and local servicing dealer, to arrange for the machine to be brought back to the dealer so the thermostats could be inspected and replaced (if broken).

During dealer service, they found one of the thermostats was broken. The thermostat was replaced and the dealer confirmed the replacement of the thermostat resolved the operating temperature issue and regens were now successful. The machine is back in the field and has been operating ever since. Thanks to John Deere Connected Support, Superior Diesel is able to continue to monitor this machine, as well as many others, through John Deere Operations Center, to catch issues such as these before they cause down time. (Contact us to retroactively apply Connected Support to your equipment)

This is a story of success for not only Superior Diesel's Service and Product Support department, but for genuine John Deere's Connected Support, our OEM and customer base, and John Deere's network of servicing dealers.
