Our marine team recently accompanied our marine service dealers to Waterloo, Iowa, for the John Deere North American Marine Dealer Event. It was a great opportunity to get a closer look at the technology and meet the people behind the engines we proudly support.

One of the highlights was touring the facility and seeing the new JD14 and JD18 marine engines being built firsthand. Watching the assembly process and seeing the attention to detail that goes into each engine gave us an even greater appreciation for the quality and reliability we deliver to our customers.

We're especially excited about expanding the John Deere marine power range up to 588 kW (789 hp). This opens the door for us to support even more demanding commercial applications, including workboats, tugs, and commercial fishing vessels.

Our dealers also had the opportunity to learn more about John Deere Connected Support and how it can help us provide a more proactive level of service. Real-time engine health monitoring and remote diagnostics give our dealers better tools to help customers troubleshoot and keep their vessels operating when it matters most.

We would like to thank our dealers who were able to attend and the John Deere team in Waterloo for hosting us and sharing your expertise. We're excited to bring what we learned back to our customers and continue delivering A New Era in Power.

Built for the Most Brutal Conditions: Powering the Toughest Jobs in Tree Care

Tree care work is defined by high vibration, constant dust, and geographic isolation. When you
are clearing a mountainside or a pipeline right-of-way, an engine isn't just a component — it is the
heartbeat of your business. You deserve an engine that doesn't just survive these conditions but
thrives in them, keeping your crew productive and your tons-per-hour high.

We know your tree care equipment tackles more work in a week than some machines
will take on in a year. We are not just developing power systems; we are creating solutions
that anticipate your challenges and deliver what you need to be on top of your game.
