Old Sunstar 16 front PTO clutch replacement

Recommended Posts


Hello, and thanks for reading this post.

I bought a used Simplicity Sunstar 16 garden tractor (mod 1691357) a couple of years ago for mowing. Ended up subsequently buying a big Ransomes mower, so the Sunstar became a supplemental mower. It has seen a lot of use, but the engine still seems strong, and my girlfriend's son loves the machine. We nicknamed it Orange Crush, and its hard to give up a machine with its own nickname.

Problem is, the front PTO clutch was iffy from the time I bought it. Sometimes it would cut off, deck would stop cutting. I troubleshot the wiring and seat interlock (couldn't find a problem), and ultimately brought it in to a local mower/tractor repair shop. They initially misdiagnosed it as an electrical issue, but in the end they pulled the clutch and said that that it was shot....bearing was toast, clutch plate was warped.....just a goner.

So, I have done some internet shopping for a new PTO clutch. OEM clutch (using Simplicity PN 1674750SM) is going for around $600+. Aftermarket clutch on eBay, Amazon, etc is about $350.

Is there any less-expensive choice for a new PTO clutch than these options? Or do I need to suck it up and lay out the cash if I want to keep this old workhorse for mowing?

I welcome any thoughts or advice you might have.

First, hello and welcome to the club. I guess if it were me, I would keep a search on ebay and my local CL for a used one. I've never needed one myself, but I seem to remember seeing them pop up from time to time for less than half the aftermarket price above. Good luck.

My 1650 cub has the new "floating" style PTO clutch on it off a salvage tractor (Sears I think). Cost... "0". They're all 12v negative. If the pully diameter is close and the crank diameter is right....

The new floating style is easy to retrofit. Spacers on the crank for front to back alignment and 1 bolt or pin to keep the magnet winding from spinning and Shazam, you're done.

      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
