B10 mower deck drive belt pulleys

Recommended Posts

hi. I have a 63 B10 with a mower deck but no pulley system for the mower drive belt. I believe the belt goes to the mid pto pulley but I don't know what it uses to engage or disengage the belt. It also has to change the belt from vertical to horizontal. any help on what it looks like or where i can get a pulley setup would be appreciated

Start here, to understand how it mounts on the tractor. http://www.simpletractors.com/operation/42_mower/42_rotary_mower.htm There are 3 belts, total, involved: 1. One goes from the bevel gearbox to the power take-off to drive it 2. One goes from the power take-off to the center arbor on the mower deck to drive the center arbor 3. One goes from the center arbor on the mower deck to the two outside arbors to drive them

thanks kent. i appreciate the reply. after looking at that, maybe I don't have the side mount pto that i need. I have a pulley directly opposite the drive pulley, probably the other end of the same shaft, that i assumed it went on but it doesn't seen to be low enough for the belt to clear the tractor

      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
