First time posting - thanks in advance for any advice.

Have a 2010 L3200 with a little over 500 hours on it. Bought it new. Machine was working fine, and with no warning, tractor would start normally, go a foot or two, and die. The machine has four safety switches that I know of: PTO, clutch, seat, and neutral safety switch working with the forward/reverse pedal.

I could relate the comedy sketch where the old switch came completely apart with little pieces flying this way and that and landing in grass, but I'll skip it.

The new switch was on order anyway. Arrived today. I failed to note the depth of the plunger relative to the mounting bracket (I had already been experimenting with it), but placed it about midway and it started, but still died when the pedal was depressed going forward or backward.

Remembering another thread on this subject from this forum, I screwed the switch 1.5 turns farther in (increasing contact with the control lever attached to the pedal). That resulted in the tractor going farther before it died. If a little's good, a lot's better, so I ended up taking the nut that holds the switch stationary off the switch and maxing out the depth setting, moving the "lock nut' to the other side of the mount. That resulted in being able to actually drive the tractor as long as I want, provided it isn't over 2.5 mph.

I'm doing something wrong, or perhaps the pedal needs adjustment. Open to suggestions or epiphanies. I'm not opposed to jumping it, but the four poles give me great pause. Anyone knowing the proper factory position of the switch relative to the mount would be helpful, but I'm ready to believe there is a second reason this new switch isn't fixing the problem.

It's not the HST switch.
It's a seat switch issue.

Do you have the WSM (aka service manual)
You need to set the HST switch in the proper position.

Yes, I downloaded it yesterday. The one I downloaded doesn't look to address the proper depth for the neutral safety switch for the HST model.

Should I replace the seat switch and guess on the neutral safety until it operates properly?

I needed to adjust the switch on the l3200 I had. This was right after buying it in 2002, so the event is a little foggy now. Mine had 4 wires on it. I don't remember what the switching arrangement was. I know there was a sweet spot and IIRC it was a matter of popping the plug off and adjusting the plunger exposure so there was an "open" between two of the wires and a "closed" between the other pair while watching my ohmmeter.

Thanks, I read something similar. I have a multitester, but have yet to see a diagram of which poles to test. I agree that with the proper testing for the "sweet spot" I could determine where the switch should be located (how far to screw it in) relative to the mount. That said, it's been in many different positions and started, with varying results on how far or fast the tractor will go without dying.

I agree with previous posts that shutting off is most likely the seat switch. If your buttocks are on the seat and you weigh more than 100# the tractor will keep running after it's started. The neutral switch we've been discussing will prevent the starter from spinning. It won't shut it down after the engine is running UNLESS the seat switch doesn't think you are sitting. That's the intended operation.

OK. I can't find anything online to test the operation of the seat switch with a multimeter, so I'm ordering the seat switch from Messicks. Will let you know how that turns out. I appreciate everyone's help. Thank you.
