Introducing Tri-Fuel. The only kit that allows your generator to run on gasoline, propane or natural gas. And if properly installed, still keeps your generator warranty fully intact.
Just swap your fuel hose (kit sold separately) and turn the dial on your generator to switch between fuel sources.
Choose your fuel source on a PRO6.4 generator - gasoline, natural gas or propane. When plugged into your home's natural gas or propane line, you never need to refuel.
When installed by an authorized KOHLER dealer, the Tri-Fuel kit keeps your generator warranty intact. Unlike aftermarket kits which may void your warranty.
Clean-burning natural gas and propane cost less than gasoline and help reduce harmful carbon emissions.
