Kohler introduces. . . Courage 15-20 HP Kohler® Engines introduces KOHLER Courage, an engine line offering the largest displacement and most powerful output of any single-cylinder engine available on the market today.

Available in six models from 15 to 20 hp, the vertical-shaft KOHLER Courage provides OEMs in the consumer turf market a lower cost, efficient, premium engine with unique, marketable technologies including dual cam design, full pressure lubrication, a tri-phase air induction system and a ported power intake - all patent pending.

The Courage line, which exceeds current EPA and CARB emission standards, also features an OHV design, electronic ignition, cast-iron cylinder liners, and a patent-pending reciprocating balance system. The new balance system decreases in-line and side-to-side unbalanced forces to minimize vibration levels.

The engine’s uniquely designed inverted crankcase eliminates the possibility of oil leaks and provides simple, no mess removal of the automotive-type full flow oil filter.

Multi-functional components include a computer-designed ported power intake, which creates air/fuel mixture tumble in the cylinder for better power and also acts as an insulator between the cylinder and carburetor for enhanced cooling, less distortion and more power.

In addition, the KOHLER Courage engine features an air filter that is 58% larger than competing models with comparable horsepower. This unique design not only provides users with a long-lasting air cleaner, but also contributes to a quieter running engine.

KOHLER Courage is designed to be consumer-friendly and easily adapted to existing turf models. The engine’s major external components, including the starter, air filter, oil filter and dipstick, are all located on the outer edges of the engine in easily accessible positions. The oil fill and dipstick are integral and designed with an extra wide opening for fast, no mess oil changes. Upon removal of the crankcase cover plate, internal components are also accessible, eliminating the need to remove the entire engine from the chassis.
