Help - won't start due to idiotic move on my part! Stood up with PTO on!!!

[David Devuono]

Is this tractor HST? If so push up and down on the forward and reverse levers a couple of times and try starting. No matter what I am doing when the tractor shuts off, I aways seem to have to play with the F-R pedals to get it restarted.

Does the pto shaft turn freely with that position in neutral? It might be worth a try to make sure there is no tension or it is stuck in gear.

So is the seat switch also the neutral saftey switch? I can move my steering wheel up and forward and stand up while mowing. Do you have a wiring diagram to trace out the circuit from the PTO to see what all systems that circuit accesses?

No, the seat switch defeated only help prevent engine stall during bumpy ride and that's all. It doesn't defeat the neutral safety switch, you will still have to be in neutral in order to start the engine.

Then it could be an open in the neutral safety switch circuit.

It sure could.....good thinking, Brandi.
Shutting down a motor while the PTO is still spinning an implement is bound to shake the machine pretty hard. I remember doing it with the key switch just once on the old JD and never again. It could have shaken things hard enough to make a wire come loose or for anything else to happen.

Some of these safety features can be troublesome. Even though it is a hydrostat, the M59 has a manual clutch that has to be pushed in order to start the tractor. I left that one in place, but defeated all the switches in the seat the first day of ownership. It's common for tractor operators to stand up sometimes.
Once when the M59 wouldn't start it turned out to be a small twig had gotten trapped in the F/R pedal mechanism and was holding it just slightly off center.

So the neutral saftey switch is on the clutch linkage for a HST then. Wiring connectors on switches nowadays are easy to knock off.
Like I said 3 days ago.............I stand up while mowing. The movable steering wheel on my Mahindra makes it comfortable to mow all day standing up if I want.

Does anyone know what the outcome was?
We are having the same problem now. A friend shut the tractor with the brush hog running and the tractor is stuck wayyyyyyyyyyyyy in the woods. Is all we get is a buzzing sound.
We tried everything, shaking handle and so on. Next step will most likely be an expensive one. We are a good few miles in the mountains and 10-12 from a main road. Luckily we were done and the path is big and smooth. All for hunting.
This is an M series Kubota 68 HP 4 wheel drive.

Have you checked for sticks/twigs pulling wire connector off the safety switches? Pto turned off? Try jumping out the seat safety switch?

We have tried just about everything. The local Kabota dealer wants us to turn the PTO a few turns as well as move the tractor frontwards and backwards a few feet. Something about pressure and not being fully disengaged! Although not common it sounds as though he has come across this problem before.

 

[Kanook]

Too bad the original poster didn't get back with the final resolution..I doubt if the tractor has been sitting inoperable since last August. Good luck Curly69 and let us know the outcome.

 

[Tx Jim]

Hyd pto &/or hyd shuttle can't have hyd pressure for any clutch engagement without engine running unless system has a hyd oil accumulator which I seriously doubt this 68 HP Kubota tractor possesses. I think moving tractor fwd or back or turning pto shaft won't aid starting problem.

 

[BLUE ME]

If it has a pto switch make sure it is turned off to start.

 

[oosik]

After I start the tractor, engage my pto and stand up to get off the tractor - the pto safety alarm buzzes about 6-8 times. This, BTW, is part of the tractors safety procedure and if this does not happen then there is a safety problem. However, nothing turns off or dies.
It sure sound to me like a wire(s) have come disconnected

I doubt he ever got it started. He defeated the seat switch and pulled its fuse. Ordinarily the switch being closed and conducting is required to run the engine. No way for it to conduct if its fuse is out.

Larry, I was wondering about very thing - if the original poster had any success defeating the switch like he said.....but I'm betting he figured it out......hope so, anyway.

Seems to me that anything manufactured has some bad with the good and this new move to interconnected safety switches isn't worked out very well. I've found it convenient to defeat a couple of safety switches on various tractors in order to be able to use the machine effectively. And there are some switches - like the HST start/safety one on our M59 - that I definitely want to keep. Like you, I've found that some of these safety switches are normally open and others are normally closed. It helps to know which is which. And I agree that if the original poster is talking about the switch I think he is, then it is probably one that is defeated by shorting it's leads together instead of by making it into a permanently open circuit. Although maybe he got lucky and pulled the wrong wire entirely since the similar switch on my tractor is not on a fused circuit.

Not being real smart on this stuff, when I want to bypass a safety switch I begin by replacing it with a hand-operated toggle switch until I can figure out just what all it does.

I'd rather be lucky than smart,
