belt hi/low prob

Recommended Posts

Ok I've tryed to figure this out by my self......... well since im posting this you can tell how I ended up. I have a 64 Broadmoor that I repainted. Insteed of putting the two speed in I used a three speed. It has the hi/low pulley. The problem is the darn belt keeps slipping of. It happends wile cluching or just after. This is the belt that only has a Idler pulley. It is not the cluch belt. These have two belts. Has any one ever had this problem? Any ideas? even if you think of somthing so small or stupid please post it. In my rage, I may have over looked somthing. Thanks every one. Elon

I had a similar problem 3 weeks ago.I had the clutch pedal with so much throw the belt was dangling past stops and pulley guides.Try tightening the clutch pedal so you have to press all the way down to shift it.

If I remember right there is a little tab thing that bolts on with the idler pulley that acts as a belt stop..Well maybe not a belt stop but to keep it from hopping off the idler pulley.. I also think there is supposed to be one under the tractor at the center double pulley (right below the dash)..

      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

      I assume it's a bosche, correct
