Factory Supersession
PA-CV742-3037 is no longer the current production specification. Kohler has superseded this engine to PA-CV742-3051.
The PA-CV742-3037 was used in select commercial equipment applications including Exmark, Toro, Dixie Chopper, and related equipment. Customers searching for the original CV742-3037 should use the current CV742-3051 replacement.

- CV740-3117

Before Ordering
Kohler Command PRO engines that share the same horsepower or CV742 model designation are not automatically interchangeable. Different specification numbers can have different crankshafts, wiring harnesses, charging systems, controls, air cleaners, exhaust arrangements, and mounting configurations.
For the best replacement match, locate the identification label on your existing engine and verify the complete Model and Spec Number.
If your existing engine is labeled PA-CV742-3037 or CV742-3037, the current factory replacement is PA-CV742-3051.
Engine images are for reference. Current production engines and factory superseded replacements may differ cosmetically from the original engine.
