I am having a problem with my mower 25 hp kohler lazer z model CH25S. It has been eating batteries for the past two weeks. I put a new one last week and in the middle of mowing my 2 acres it just died and would not restart. I put a new battery on mowed today and all was good until I turned it off to clean it off and it would not restart until I jumped it. Any help would be greatly appreciated.
