Tractor runs wide open want shut off

 

[Dmacleo]

ok.
prob a ****load more info needed.
like does the cable retract?

 

[WranglerX]

Check to see if timer relay for shut off solenoid is working.... May be blown fuse, may be bad relay timer, may be bad solenoid.... Shutdown relay/timer supplies 12VDC to shut down solenoid for about 10 seconds when key goes to off position.... Information supplied is rather sketchy....

The fuel cut off solenoid failing to operate would not explain the wide open throttle.

Assuming OP wouldn't have left the throttle open, it seems like there is more than one problem.

 

[Dmacleo]

or....give us a good description.
I mean really..
Tractor runs wide open want shut off
is not really good info.
I have a 2010 GC2400 with a stuck throttle cable. it costs 35$. pretty sure thats more than what this topic is about.

I hope he's not describing a runaway. Or the problem may already have solved itself, catastrophically. "Won't shut off" and "running wide open" are generally not a good combination for a diesel.

Definitely need more information.

shut the fuel valve off it will shut down. just saying...

Not if it's pulling from elsewhere. On a few occasions I've seen them pull oil from the crankcase and burn it instead of the fuel. No shutting that off until the bang or seizure unless you can seal the intake or get some sort of inert gas into the intake to cut off oxygen.

then you don't deal with a 3 cln iseki massey like many of us in this topic do. twist that lever it shuts off.
hell sometimes getting it to fire is an issue.
this is not a 2 stroke Detroit diesel.

Doesn't have to be a 2-stroke to pull oil from a leak somewhere. I've had it happen on a wore-out 3 cylinder Yanmar...

well, I run one daily and can tell you when throttle cable sticks full open at 2800prm on a GC tractor twist the lever engine shuts down.
but you be you, you are not running a GC tractor.

Okeydoke.

Sorry Dave, but twist what lever?

fuel shut off lever beside the filter. crap dies in a hurry then and if lucky you may get it started again. you could pull the shutoff solenoid but...this lever is faster. much faster. so very fast. damn....ask me how I know.

edit:
when this happened my throttle cable was frozen full bore. I pulled fuel pump shut off but kept running due to fuel in bowl and gravity feed. pump was not running but...still...jesus...I shut fuel off and it died. then I had to replace cable but...meh...whatever.
and I have a new throttle cable sitting in my shed....just in case.....
oh yeah. lot of ice on key.had just finished snowblowing yard. so much ice on key could not twist it.

Dave, just out of curiosity, are you familiar with what a diesel runaway is? It's not stuck wide open at 2,800 RPM... It's uncontrolled fuel draw from any source - be it the fuel tank, or oil from the crankcase. This can be caused by heavily worn piston rings or sometimes a damaged fuel shutoff solenoid plunger (or say one that's not seated correctly after replacement) amongst other things. Almost no diesel engines have an air throttle blade like a gasoline engine. RPM is controlled solely by fuel delivery. If the engine is pulling fuel (oil) from somewhere other than the fuel line, turning the fuel shutoff valve will likely do little or nothing to stop it.

This condition will not stop at 2,800 RPM, either. In general it will cause the machine to overrev, hard. Like potentially up to several multiples of the standard redline. Then often there is a kaboom or seizure if the engine can't be shut down quickly. Without more info from the OP we don't know *what* he is actually describing.

Looks like we'll never know what happened. The OP has disappeared after 3 posts.

We call them one post wonders.

Very common occurrence here.
