kt issues

Recommended Posts


ok ,so dad and I just got another kt powered tractor , got it home ran it around for a bit to test her out , decided to mow with it so pulled deck off the 17 GTH-L and installed on new tractor.  any who was mowing with it for about 10 mins and it shut off. got her started after a few minutes and made another stripe and a half and shut off again .checked spark and didn't have strong one so swapped coil. it stays running fine at idle but when you have it under load it keeps shutting down , oil level is good ,fresh fuel, just don't know what is up with it . any help is appreciated

Did u Tune it up?

Carb clean ?

Spark gaped good ?

points adjusted to 0.20?

Did u check to see if any of the PTO pulleys  seized ?

Does the drive shaft spin freely with no binding or issues ?

Could be the relay, if it is weak or has poor connections it could be heating up  while charging the battery, and tripping out.  Cutting power to the coil.  Cools off and resets.

      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
