Service Manual Kohler XT-6 Owner's Manual Kohler XT-6

  • Every part, every component, every system on our engines is guided by our exclusive Performance Engineering standards. Take our innovative Smart-Choke™ technology. Available on Courage® XT-Series engines, Smart-Choke requires no priming, and therefore eliminates the risk of flooding the engine. Just pull the starter recoil – or for electric-start engines, simply turn the key – and you’re up and running.
    That’s because KOHLER Smart-Choke automatically adjusts the amount of fuel needed to start the engine. It’s features like our Smart-Choke that sets us apart, and another reason why you can depend on the worldwide KOHLER® reputation for excellence.

    Made the only way we know. Commercial-grade. Everything you’ve come to expect from KOHLER® engines for over 75 years – now available for the walk-behind market.

    From their cast iron cylinder liner to their heavy-duty forged crankshaft, the new Courage® XT-Series engines are tough, reliable and commercial-grade. But while the engines work hard, the consumer doesn’t – thanks to a long list of operator features including smooth, ball bearing starts and wide-opening gas fill.

    Overhead Valve Design. Super-efficient combustion for smooth, powerful performance with lower fuel consumption and cleaner emissions.

    Commercial-Grade Cast Iron Cylinder Liner. For extra durability and longer engine life. And while others make cast iron liners optional, we make them standard.

    Heavy-Duty Forged Crankshaft. Forged – not cast – for superior tensile strength and less chance for failure. Made tougher for heavy loads and extra-rough mowing conditions.

    Flywheel Ball Bearing. Reduced friction and pulling effort for fast, smooth, easy starts and provides extra lubrication for mowing at all angles.

    Wide Gas Tank Opening. Easier filling, less spilling. And simple, easy-to-see fuel-level checks for the consumer. Another KOHLER exclusive.
