Kohler M17 Engine

Recommended Posts


I did not know that this engine ever existed. Magnum 17?


Vertical shaft engine.  Does not show up on Kohler's web site.  (Later became the MV18?)

Used Kohler M17 Magnum 17  Engine 1" Crank from Cub 1730

The gentleman I bought a M18 from to re-ring,   had it to put into his Gravely after re-ringing.  He told me the only difference between the M18, and the 16hp version Gravely used was only the Governed speed.

For what it's worth, as a vertical I believe it should have an MV model designation to it, as would the M18 / MV18.   That being said, Kohler's site is great for owners and service manuals, and there are neither for a M17 or MV17.  I believe it may have been a proprietary designation for CUB, for whatever reason.  Those are the only Magnums I have seen with a 17 rating;  CUB vertical engines.  I don't think there is an actual Magnum 17 horse engine.  JMHO

FWIW the photo shows a horizontal shaft engine not a vertical

That's what I thought at first also.  But it's a vertical; check the position of the dipstick - if it were horizontal, they're be oil everywhere.

Some years of the production run, the blocks were the same, it is possible to make a vertical into a horizontal.  Someone here did it pretty sure. have to change intake, oil pump pickup, dipstick etc.

In my most humble opinion, this is not a converted engine and was a vertical from the git-go. The decals on the tins, the oil fill, the mounting plate at the crank (which is entirely different from a horizontal "closing plate"), and again, the 17 HP designation that I have only seen on verticals for a CUB.  I am not saying that simply because I have only seen the 17 on a CUB vertical that that's the only 17 Magnum ever built, but that's the only place I have seen them.  That and the fact that there isn't any Kohler manual for a 17 horsepower Magnum all leads me to believe this was a proprietary engine for CUB.  

Or, I could be completely wrong.  It has happened before.  Once I think.  When I was 5.  Or was is it 6?...................&:)

Brett is correct. The Cub 1730 is a vertical shaft tractor. I have the 917H with the converted engine. I bought it from Darin Butcher (Country) who originally did the conversion.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time
