D/A or Sunstar 60" mower belt

Recommended Posts


While repairing my deck and taking my sweet time to do it over the winter. I cannot remember how to route the belt w/o removing parts. Nothing in manual about bit either just a diagram of the route. What am I missing?

Lower the deck all the way down and remove the covers,  Release the tension on the idler with a long screw driver or breaker bar and pull the belt off one of the pullies.  Once the belt is free from one pulley, you can let go of the idler and remove the belt from the other pulleys.  

To install the new belt, route it as shown in the diagram but make the idler the last step. Move the idler with the screw driver, slip the belt over and release the idler so that tension is now applied on the belt.  Remove the spark plug wires and turn the blades by hand a couple of revolutions to make sure it is on correctly.  Good luck.

Now I almost lost my NEW belt, gear drive pulley sitting lower than center pulley and jumps off. I loosened that gear drive bracket to install belt and reinstalled in same location. How do I realign pulleys?

Are the pics upside down???  Didn't load correctly??  Here is a picture of the parts list for the model 1691339.  You say you loosened the gear drive bracket.  Do you mean the un-numbered part I have circled?  When you reassembled, was the deck sitting flat on the ground?

No they are not upside down, top picture camera was at an angle and I do have the FSM. Yes the circled part, I removed the the 4 front bolts and loosened the the rears and pivoted up just enough the slide belt through. Had the hardest time realigning front mounting holes until I stood deck up, then it was a breeze, however I did slam the deck down a little while lowering it back down before tightening everything back up. Pictures are from both sides of deck, will take more pictures this morning.

thanks for sticking with me 🙂

      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
