Product Summary

This Kohler Command PRO OHV V-Twin Horizontal Engine has a durable, long-life design with hydraulic valve lifters that are oil pressurized, ensuring that push rods stay in constant contact with the rocker arms. Requiring no adjustment, the valve train is virtually maintenance-free. In addition, full-pressure lubrication delivers continuous lube to critical engine components, even at a 25° angle of operation and optional oil cooler regulates the oil temperature, extending oil-change intervals. Large capacity, in-line fuel filter provides extra protection against dirt particles that can clog fuel lines. High power performance comes from overhead valve technology, which provides greater volumetric efficiency and a higher compression ratio. This produces more power, improved fuel economy and cooling and reduces oil consumption. In addition, there is virtually no carbon build-up, reducing overall maintenance costs. The variable speed mechanical governor promises smooth performance, regardless of application or fluctuating demands for power. U.S.A.
