900 Series Center PTO

Recommended Posts

Les
I have two 900 series tractors. The center PTO on one does not have the second "ear" to move the idler pulley to run the snowblower. Apparently this feature was added midway through 900/7100 series production. Could you just weld a new ear on?

On your 900 that does NOT have the 2nd ear, are both idler pulleys attached to the pto arm? How about your other 900 that DOES have 2 ears, is one idler pulley attached to the frame instead of the pto arm?

Hi, I believe that all of the 900/7100 should have the front pulley on the center PTO mounted in a slot in the tractor frame. This pulley is moved forward or backward to tension the belt. There is a red and green decal behind the rear pulley arm. The front pulley is moved to position the arm in the center of the green triangle when the tensioner is tightened. The 700/3400/7000 [short frame] tractor have both idler pulleys on a common pivot shaft and that is why is is a problem to drive a HEAVY load like a snowthrower from the center PTO on these tractors. On the 7100/900s the fixed problem solves this as the tension is on the slack side of the belt and the loak pulls against a fixed pulley. My 2 cents worth and its free value accordingly. Happy New Year. Al

Les, I never actually saw one either. I'm just going by the Simplicity manual. On some 7100/900 models, it sure looks like the "Back" idler is attached to the pivot arm, and the "V" idler is attached to a bracket on the frame. Sorry, just trying to help. Happy New Year.

      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
