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.
