second question does anyone know what belt I use for the power takeoff , the one that's on now keeps coming off when I disengage 

the lever on the left side. 

Thanks so much for all help I will post pictures when I get the deck on!

Keeps running means it is not grounding the coil, take connection at switch and clean contacts , clean switch to frame ,might be rusty , assuming all wiring correct .

If this  didn't help, u have to do a continuity test on the ground wire .

Others will shim about belt

I had a similar situation on a B10 - nice paint job all over and few ground connection opportunities. Rather than remove bolts and scuff things I ended up running extra wires back to the engine housing, which is grounded.

As far as the problem with the PTO belt coming off, make sure all of your idlers spin. Another thing to check for are any belt guides used to hold a belt in place while it is disengaged that might be missing. Simplicity equipment I see usually has either a wire guide or a bracket preventing the belt from coming off.

      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
