Ariens S18-H Mower, Lawn and Garden Tractor Category
Original Model: Kohler K361 OHV 18hp
There is no direct replacement for this, however the 71179 will work with very minor changes. The conversion kit that we have for the GT-16 tractor should also fit. If you use our Vanguard conversion kit in this tractor you may have to notch out around the starter for it to sit down in the frame.

While we may have sold many engines listed above to be used for a Ariens S18-H 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.
