My first Simplicity was a 717. The starter/generator gets hot but this one got real hot and you could hear the belt groaning like when there's something stuck in the auger of a snow thrower (although there was no bearing noise, I think it was stuck on charge) and then the magic smoke came out of the regulator (or at least it gave off that acrid, burnt electrical smell). I read all of Al Eden's series of articles, which provide a good education and are exceptional in that they explain the complicated in a way that enthusiasts who are not engineers or mechanics can understand. I was later shocked to discover he is a real, living, person who posts here regularly. My best guess was that the person who sold the 717 to me had replaced the short frame starter/generator with a long frame unit without changing the 2 pole regulator to a 3 pole regulator and this resulted in overcharging of the starter/generator and eventual burnout of the 2 pole regulator. Sadly the problem never got resolved because I remain unsure of the issues involved and the costs are potentially too high for this class of tractor. Your B-10 is a vastly more valuable class of tractor and well worth sorting out this problem. I am guessing you must determine if you have a short frame or long frame starter/generators and/or 2 pole versus 3 pole regulator. I never got to the point of how you determine if you have a short frame or long frame starter/generator (hopefully we are staying within the boundaries of censorship here) and, if a short one, should you install a long frame and go with a 3 pole regulator?

      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 
      Paul
