My ex-BIL has a zero turn mower with a Kohler Carnage (Courage) engine that is in the running shape of most Kohler Courage engines. I am looking for a replacement engine. This mower uses an electric PTO clutch, so I need an engine that can charge sufficiently. My questions is...do all Kohler Command engines charge at a high enough amperage to charge a battery running an electric PTO? I think I've read somewhere that you need a minimum charge rate of 7.5A to run a PTO clutch and keep the battery charged. I've been looking at single cylinder engines 12HP-15HP. Thanks.
