    We did fit a 37hp on an early prototype but never took it further. It would more than likely fit on the mower but there are a couple things to keep in mind, first the muffler from the 31hp won't work on the 34hp and second depending on what clutch is on the mower currently it might not be rated for that horsepower. The first clutch we used in production was spec'd for the use up to the 37hp but since we didn't use that engine we changed the clutch.

    Best Regards
