Sunstar 18 front PTO not engaging

Recommended Posts




Recently purchased a Sunstar 18 (Model #1691528) a month ago and have mowed my lawn a few times without issue.  This morning I attempted to start the tractor as usual with nothing happening when turning the ignition.  I noticed that the Front PTO light was lit when the ignition was in the start position.  I turned the switch to the off position and toggled the PTO to the on position and turned the ignition.  It started up without issue, however when I toggled the front PTO switch to the off position it remained off and when I toggled it back to the on position it remained off..So apparently now my front PTO will not engage. It will now only start if the PTO switch is in the "on" position.. Any thoughts on potential issues?  Also, does anyone happen to have a wiring diagram for this model with the 18hp Kohler magnum?  I found the operating manual and the parts manual on this site but not the wiring diagram yet.  Thanks for the help!

      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
