[hitman12]

I have a john deere 430 diesel lawn and garden tractor that runs fine until you take it out of neutral i by passed the neutral safety switch and it runs fine but you cannot cut the deck on cause it dies i put a new seat switch on it twice a new pto switch and a new neutral safety switch also. My modle does not have a brake switch or i would have changed it as well PLEASE HELP !!!!!!!!!!!!!!!!!!!!!!

Do you have dash lights ? I had the same problem after replacing a busted hydraulic tube. It would start but would die when taken out of neutral or engage the PTO. I has also lost my dash lights. I checked the fuses and they all looked fine. I replaced them anyway and everything started working - might be worth a try.

Hi, did you ever solve this problem? I have the same problem and I do not have dah lights now and I used to. I am about to go and change my fuses even though they look good.

That symptom is suggestive of the machine not recognising the Seat Switch. The S/No break has the earlier 'bendy reed' type of switch and the later models have the push-button type. Bendy Reed was somewhat unreliable in my experience.

Do any of you above have the Tech Manual you can post a wiring schematic from?

As well as the Seat Sw. and Neutral Sw. there should be a Brake Switch and there is a "Time Delay Control Module" which I presume is either Glow Plug timer delay or Operator Off-Seat Delay?

For diagnostic purposes only you could bypass the seat switch to test that particular circuit.
