Anyone have any ideas.......

Mower: Toro Zero turn with 19hp Kawasaki motor.

I have 560 hours on my 2006 mower. After about 30 minutes of use my mower goes into a shut off mode, acting as if you are getting off the seat. Once it hesisates i stop, put the emergency brake on, and open the handle bars out as if i am parking the mower, it then regains a little life, for a short matter of time. If i let it sit for 20-30 minutes i can mow another 10 mintues but then it does the same thing again, sputtering after 10 minutes of use.

What i have done so far:

I replaced 2 ignition coil packs, 2 new plugs, run 2 bottles of fuel treatment. and now i am stumped. The hardest part is the fact that the mower works for 30-45 minutes until it gets hot and then the problem above occurs. ANY SUGGESTIONS?

I don't have a clue but when you say as if I am parking the mower.
I assume you turn off the blades?
Which would remove load from the mower. And make the engine use less gas.
Maybe you have a fuel delivery problem.
Dirty fuel filter, bad fuel pump,bad fuel line or trash in the bottom of the gas tank?

test the saftey switches while hot

Are the gas cap vents working? You can probably mow for a while without them but then when it cant suck any more fuel it sputters out. Let it sit for a few minutes and it can suck a little air back in the tank. Just a theory..

i have a exmark ,does the same **** "aggreviating".under the seat i have a spring with a long bolt in it. i took the wire connector off and put in a jumper across the connector stopped the problem.maybe yours is diff,but its worth a try.its deff in your safty switches.

OK.... Im back now.. I picked the mower up from the TORO dealer, they double checked everything, mowed for (what they said) 2 1/2 hours and could find know problem.. I paid the $150 bill and said i will see what happens, maybe it was just BAD gas.

So i mowed last night and on my 4th yard (acre each 4). It did it again, this time i let it sit for 2 mintures and then started it back up. It ran, then sputtered a bit, like it was going to shut off, and then kept going for the next 15 more minutes i needed to finish my yard. I then parked it since it was late and getting dark.

I still dont have faith that it is perfect, but could it be just bad gas and will sort it self out. I have had this checked over by many different quality folks. My seat swith is supposely OK. I have printed out the post or forum on this matter and have given the mechanic a copy the website forum..thanks for your posts and response. im ready to be done with this problem

I discussed with a mechanic friend at local golf course and he said you may have small float inside carburator that is sticking shut. He has stopped using all toro's due to this float valve problem. Says when you take apart they don't put in the right way they will shut down and stop fuel flow.

Unless they did it at the shop, which for $150 they could have
done as much but from the sound of things they just looked it over?
Anyhow, try replacing the fuel filter(s).

If it makes you feel any better I go through it, too, maybe we're in the wrong business.
But yeah, replace the fuel filter(s).

Did you ever find an answer? I have the same mower with the same problem. It did it last year too and they took it in twice and figured float was stuck in carburetor. I use non-ethanol gas but apparently it still leaves a gum residue after a while. I been using it for 2 months this season and just one day it stalls exactly as you say. I have to learn to clean out carburetor as it is $80.00 just to have it trailered to repair shop.

I have a new Toro 75750 ZTR TimeCutter mower. It has the same issue (shuts off when hot). It sputters and coughs like it is running out of fuel, then it dies. But it has fuel. And taking the fuel cap off doesn't help, so it's not a plugged fuel cap (no vacuum being created.) And that doesn't help it restart either. If I blow the mower off with a blower (everywhere, to include engine and filter) it will restart but won't run but 5 min before dying again.

Is there some kind of 'overheat' circuit on these things? I thought maybe ignition coil overheating and shorting out, but that was replaced by a previous poster (twice!) and it wasn't the problem.

I'm tempted to try the jumper for the under seat safety switch just to see if that is the issue (simple/cheap to try.)

But it would be great if the original poster (@nwalls4) would come back and fill us in on what he eventually found or figured out. Any thoughts on this? I don't want to pay $80 for it to be hauled to the dealer, then they don't find anything, and charge me a $150 to check it out and not find a warranty issue to fix. I'm mechanically inclined. I should be able to fix whatever it is...if I can just figure out what it is!

Gasoline engines need three things basically to run, air, fuel and ignition. When the engine stops, if it has a carburetor, try spraying some carburetor cleaner or brake cleaner in the carburetor. If it starts and stops, it’s a fuel problem. If it doesn’t start and stop, check for spark. Because you mentioned that using a blower to cool the engine will get the engine restarted, have you checked/ cleaned the cylinder cooling fins and the blower housing?
Good luck.

First of all, start your own thread.

Second, if it’s new, it’s under warranty.

No.

A previous posted replaced the magnetos on your mower? 🤔. That’s a new one.

Well, he left 1 month after he joined……. THIRTEEN YEARS AGO! So, I’m gonna say he isn’t going to come back. Even if he does, he won’t remember what he did. Probably doesn’t even own the mower anymore. I also bet he took it to the dealer.

Yep. Several. But it’s going to be a damn long list no more information than you gave.

I think you’re paranoid.

Really? So what have you tested?

Mechanically inclined people are good at figuring out problems.

Part changers are good at changing parts. I can teach a monkey to change parts.



So….. go start your own thread, and tell us what you’ve done to diagnose this issue, and what you’ve found.

OR

Take it to the dealer since it’s new.
