Seat switch? Try to jump it... Welcome to tbn.:welcome:

These things are quirky sometimes.....like the seat switch, if you are light weight and the seat is cold, maybe that's it. Sometimes one of the control handles just isn't quite right....jiggle them some more for the start position. Dirt/dust, cold temps can account for the no start, especially if your tractor has been trouble free up to now. Obviously, a poor battery ground would do the same thing. Good luck, whereever you live. ... and welcome to TBN

Won't start or won't crank???????

I would make sure the PTO switches (rear and mid) are both off. Toggle them several times each. If that is an HST -- the peddle needs to be in the middle or it won't crank. Then push the clutch down several times.

See if it cranks. Yes? done. No...

Inspect the clutch mechanism to see if there is some debris keeping the clutch from going all the way. Inspect to see if the plugs for the switches are all tight. Unplug, add some dielectric grease and replug.

See if it cranks. Yes? done. No...

Time to get out the ohm meter and see which switch is not working or where the wire is broke.

i checked the clutch with the dash removed and the the pedal is contacting the switch. at the time this happened it around 56 out side. checked both switches with meter liked service manual said to and where fine. the other thing that i found is that the pto light in the dash will not go out. the hst petal is in the nutral postion.

Then focus on the PTO switch. It sounds like you may have a piece of "stuff" stuck in there holding it so the tractor thinks it's on.

checked pto switch with meter and there is no stuff around the switch.

If you have a battery tester, put that on the battery. I've seen a bad battery do some strange things. Maybe try putting another battery that you know is good in it and see if that does it.

Need to find out if there is supposed to be voltage going through the switches or no voltage for the start signal. Then use the volt meter to trace the circuit.

Does anything else work....dash lighting, whatever.

most tractors have a large main fuse somewheres by the starter. Not sure about your specific brand.

I 2nd the try another battery post from above. It amazes me how many issues of no starts are either from batteries being shot under a starting load OR a badly connected ground wire where it attaches to the frame

is there power to the starter. are the battery terminals clean and tight. if you are sure all the saftys are in the right posion. jump the safty cercut to aliminate them as a problem. check for fuses and the like first. good luck.

Check wiring going from dash area to rear seat area, shorts in wiring has caused similar problems on other tractors, especially if there is an indication of mid PTO when none is present. Also make sure all fuses are seated good.

found the problem. there is a 5 amp fuse that was labled key stop. found that it contraled the pto, clutch switches and also the fuel shut off solinoid.

thanks for the help

Glad you found the problem! My past electricial experiences always end up with some dumb .50 cent part that causes a great deal of problem until found. . . .John

Glad to hear it. I would take a look at everything on that circuit and try to see if something is going bad or a wire is damaged. A fuse shouldn't just blow.

Any idea why the fuse blew in the first place?

You sir just saved me hours of work. I just had the same problem when I adjusted the seat. Stupid pto light came on and wouldn’t start. I tore the panel up and everything looked great. I stumbled across this post and looked at my fuse and sure enough, it was blown. Replaced it and the light went away. Tractor starts up and runs fine again. Not sure why it blew but it did. Thank you so much for the help and I’m glad you started and ended the post. Most guys just post their problems but never actually say what it was.
