B-10 clutch ?

Recommended Posts

Hi all. This mite sound like a dumb question so bare with me. Apond diving my b 10 for the first time under its own power I went to put it in gear and got the most god allful grinding noise. Of course I recheck twice the 3/4" air gap or free play on the clutch rod. Did I miss something else? Do you start in gear with clutch disingaged? Or is it simply the wrong belt, for which its orgene I don't know It was on the tractor when I got it.??? Like I said mite be dumb but smart anough to ask.. 8o) polo

Hi Tim,
Do you have a "Guard Assembly, Belt" (as it's called in my Simplicity book) around the front pully?
I first thought of it as a guard but have come to the conclusion that it's really a 'belt brake' - it's
what stops the belt when the clutch is depressed. John

Tim, When I put a new belt on my B12 I had the same problem. I adjusted the guard over the drive pulley and no help. When ever I wanted to put the tractor in gear I had to reach back and stop the transaxle pulley from turning. I concluded that the new belt was to stiff and that the problem would go away as the belt got broke in. Well it's now be on the tractor for about a month and causes no problem at all, shifts just like it did with the old belt. Tim

I had the same problem. I found using an A-belt
eliminated most of the grinding,also it helps if you shift
to 1st gear first to stop the belt from freewheeling on it's own before
shifting to a taller gear.

I had the same problem when I installed a new belt. Our local small engine genius said he thought you could make a "belt stopper". This would be a small piece of metal drilled and attached to the outboard side of the end of the idler pulley and bent at 90 degrees adjusted to drag against the belt slightly when the clutch is depressed.

      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
