Built to last since 1920, KOHLER engines have been battled-tested at the South Pole, Hoover Dam, WWII and victory lane. And today, we power the toughest equipment in the commercial world. From heavy construction to lawn and landscape, the pros count on KOHLER. Every KOHLER engine is meticulously quality-tested start to finish. Our engineering team runs tens of thousands of hours of performance tests during our design process. Everything’s examined — down to the bolt.
