Notes

Nearly a century ago, the first KOHLER® engines worked sunup to sundown on American farms. Now

they power hard-working equipment for construction, power washing, welding, lawn and landscape,

and yes - agriculture.

From the world’s first four-cycle, water-cooled gas engine in 1920 to the diesel engines we developed for the

U.S. Navy in WWII to the industry’s first electronic fuel-injected engine, we’ve built our reputation on high-quality

engines that get the job done. Every time.

We know the torture you put an engine through. Sixteen-hour days. Punishing weather. Monster inclines.

So we make sure it lasts. Every engine is Kohler-engineered and extensively tested using stringent Kohler

quality criteria.

You rely on us to make a living. We won’t let you down.

We stand behind our dealers, and they stand behind our warranty. It’s customer first, every time. Need a

replacement part? It’s in stock now, period. There are 13,000 dealers in our service network, so if yours

doesn’t have it, he’ll get it in 48 hours or less.

Only Kohler Engines makes genuine parts for

KOHLER engines. They’re built for the long haul.

And designed to give you peace of mind.

For more information, contact your KOHLER source of supply.Or call toll-free in the U.S. and Canada 800-544-2444.
