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.

most engine that are on the mowers that have a manual blade engage do not have a charging system with enough amp capacity for the electric pto. So if you have a used engine for replacement check the amp charging capacity.

I did some research and found the answer.  I asked the original question because I was finding some engines that had unknown original installations.

 

Kohler used a 3A or 15A charging system on the Command engines.  The 3A system has a couple inline diodes to convert AC to DC (unregulated charging).  The 15A system has the mounted 3-wire rectifier (regulated charging).

That is good information now if you can find you a good command engine you will be in business,
