2106761 Front PTO Pulley

Recommended Posts


I have a 3112V and just recently picked up a 36" Snowthrower for it. Everything is there but the drive belt and the front pto pulley, 2106761.  Does anyone have one of these available, or can anyone tell me the diameter of the pulley.  A local Amish machine shop has just about any size pulley available and can adapt to whatever is needed.

I believe the 3112V is a FDT (no running boards), so your snowblower setup should have a clutch built into the front hitch.  The OEM front pulley was cast iron and measured 4 3/8" OD.  It's a shallow groove type pulley (belt basically sits flush with the top of the pulley).  Here's a pic of the pulley mounted on my B-110:


It's hard to see in the pic, but there are 2 belt guides on each side of the pulley.  They are important - they help position the belt so that when the clutch pressure is released, the belt disengages from the pulley and doesn't hop off the pulley.

I think I have one I might be able to pull of of my RBT.  For the first year, I did not have a single pulley hitch and used a front pulley.    I believe the pulley is for a 1" shaft, not 1-1/8" however, so check your crank diameter.

      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
