Simplicity 7018 Mower, Lawn and Garden Tractor Category
Original Model: Kohler K361 18hp
This tractor uses the Kohler OHV single cylinder that is no longer made and there is nothing that will directly fit it. One of the spec numbers was 23107a. Kohler discontinued this engine over 15 years ago, and it was not designed to use unleaded gasoline in which makes the engine run hotter. Kohler recommends using the K341-71179 16hp, but the muffler does come out at a different angle and you would have to do modification to make it work.

While we may have sold many engines listed above to be used for a Simplicity 7018 Mower, Lawn and Garden Tractor Category, we are NOT claiming these are exact replacements unless the product notes explicitly say so. Many original equipment engines may no longer be in production because of obsolescence or EPA regulations, so in some cases there may not be an exact replacement available. Our intention here is to show that other customers have utilized these in the equipment shown, but may have had to make some modifications to do so. If we know of any required changes, we will list those, however, some adapting during installation should be expected.
