25 HP Kohler engine on a craftsman model. Where is the oil drain?
. I don't have a manual, Where is the oil drain?
The oil drain is on the underside or the lower side of the engine. There is a drain plug, about squared where you can drain all the oil out. There is a plastic snap over the drain plug and is normally red in color.
There should be a oil plug on the side of engine close to the bottom below the oil filter.
