Most likely it's rings.  However there has been discussion before on breathers not functioning due to degraded rubber valves.  The updated replacement uses a metal reed.  I still think its rings.  To correctly determine the culprit, you should perform a compression test in conjunction with a leak-down test to determine the area of failure.  These are very good engines if taken care of & monitored.  If it is a Series 2 engine it is even better & parts easier to find.

That's the short answer according to MHO.  If you search the posts you will see a plethora of information regarding the Kohler KT-17 & KT-19 Series 1 & Series 2 engines.

If the price is right & it's a Series 2 engine, it should be repairable.  But you don't want to wait until the rod breaks & grenades through the side of the crankcase.

Not sure if you have a series 1 or series 2 engine. The series 1 are prone to piston damage from carbon buildup on the ridge of the cylinder. As ShaunE said, these series one engines can be extremely expensive to repair IF you can find the parts.

Hope and pray it's the reed valve in the breather and not piston damage.

      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
