Front PTO not working, toggle switch appears culprit

Recommended Posts

Bahmi

In acquiring my first Sunstar, while it runs and mows great, I have a number of little itches that need scratching. I noticed today that my front PTO toggle switch comes on briefly, then cuts out virtually every time I try to engage it. My lawn looks like it has a case of the Morse code, dash/dot/dash/ dash, etc.

The switch has a small, thin nut that holds it on the dashboard, seems like I need to unscrew it and try to pull the wires up through the hole.

Make sense or am I barking up the wrong tree?

If it's like most switches, after you take the thin nut off, you remove the switch from the backside. 

Before you mess with the switch, I'd check the electric PTO ground.  I think it passes through an interlock module and the module might be the issue. 

If you direct ground the electric PTO and take the IM out of the circuit, that will indicate the ground side is the issue, not the +12V supply.

Hopefully someone with SunStar experience will chime in.  I seem to remember Brettw having the same issue.

Another possibility is a marginal battery not having enough volts to "lock-in" the electric clutch.

Happened to me on the Cub Cadet (we got with the house).  Was doing the same thing.  Once I replaced the voltage regulator, the battery stayed charged and problem went away.

 

My results, yours may vary accordingly.............

I have noticed that the gauges on the dashboard of the Sunstar are very possibly not working properly. With a full gas tank, the gauge does not show over a quarter. The battery charging rate is not above 12V and should be 13.4 or thereabouts. I am charging the battery and will install it and see how the gauges react, as well as how the electric clutch reacts.

      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
