Top of the range, 17.5HP vertical shaft engine. 2 year warranty.
Equal to any brand name engine on the market today.

There are a few things you need to check before purchasing any vertical-shaft engine to ensure it fits your mower.

Our engine has a Briggs & Stratton bolt pattern. You can view a schematic of the bolt pattern in our thumbnail pictures. If you have a Briggs engine then the bolt pattern will be a perfect match. Bolt size: M10 x 1.5 (bolts not included).

The output shaft on our engine is 1” (25.4mm). Almost all ride-on-mower engines with a HP rating between 9hp and 18hp will have 1” shafts. The thread pitch for the output shaft is 7/16 20 UNF -2B.


If your mower has only a limited amount of space for the engine to fit into (i.e. it is under a bonnet) then you will need to check the physical dimensions of our engine before purchasing. A schematic of the engine’s physical dimensions can be found in the thumbnail pictures of our listing.
