Drain out the excess. Too much oil will damage the engine.

its not how much can the engine handle but how much your transmission will hold up to. A lawn mower can drag anything along with the proper transmission
That depends on what size of Kohler engine you have ( my 149 cc Kohler engine on my lawn mower takes ( 20 ounces / 600 ml )
