Guardian angel was watching over those boys while they were trying to get it shut down. That engine could have turned loose at anytime and took out every guy standing there! Hats off the the engine builder! I’m sure a new safety rule about fuel dumps will be coming soon!
Whoa!!!! That got sketchy real quick 😬 glad to see they got it shut down before it destroyed the whole tractor, been awhile since I’ve seen one run away at the starting line, usually happens at the end of the track
I gotta give credit to everyone at the event they didn't panic sled operator keep the sled in place which held the tractor in place pulled the kill switch snuffed out the turbos great job nobody got hurt
The fact that he was dumping the fire extinguisher into the turbo (and it actually had a positive effect) indicates that the air shutoff failed. It appears that they stopped it by halting the fuel flow..
That isn't how a runaway engine works. It is runaway because oil or fuel is leaking in so it just starts accelerating and sucking in more air and getting faster. The fire extinguisher basically fouled up the incoming air so badly that it could no longer fire by itself. When fixing diesels, often this is stopped by just blocking the air intake but you got to be fast.
@@user-mt4ny2zw7t Every single tractor in this class is required by rule to have a knife gate air shutoff. It didn't work, obviously. Secondly, if you understood pulling engines, you would know that a heavily modified injection pump can stick wide open (full rack travel). It's not "leaking in," it's literally being dumped in. The only way to kill that is with a properly working air knife gate OR by blocking the fuel line to the pump...although it takes some time to empty the remaining fuel in the pump.
Thank you for your insight! I don't know a lot about motors so this was very informative. What a scary thing that can happen! I'm glad he was able to act quickly.
The kill switch worked partially, you can see change in fire out the exhaust leaning it out. Lot different scenario when there’s that much air trying to move past the guletine
That would have heated up the flywheel so fast it would have flown apart. I have seen it split tractors in half. Those guys are super lucky to have done what they did and not been killed.
Oh my FREAKING GOD !!! The more of these "Runaway 's" I see, the more afraid I am of my 6.4 Powerstroke !! It's had a screwed up turbo housing for a couple years.... borrowed time ???
Its pretty unlikely on a stock or near stock engine these days, especially in a street environment. Back in the days of the 2-stroke detroits yiu mightve had to worry about it a little. But I've never seen nor heard of a modern diesel running away unless it was in some kind of competition event or on a dyno.
Got to give it up to the engine builder that it stayed together and nobody got hit with shrapnel.
I agree. Sounds like it could be a Lemke Motor

Yess

yep cause the turbo usually lets go at the end of the track, since this wasnt a charger failure already makes it pretty rare
Just a opinion but does anyone think that you can get too many things saturated with the joy juice starting them,

I was thinking the very same thing....
Met these guy's a little bit ago actually! Theyre really nice people

Did you watch the video? The driver put the tractor back in neutral and the kill switch didn’t work. I had to manually close the guillotine.
@@belllpatrick yeah I did either way everyone did what they were supposed to do
With that kind of runaway you'd have thought it was a driptroit diesel 😂

I guess it didn’t have a 3- way dump valve
That was a great idea using the fire extinguisher to try to choke the engine. If it had been a bigger one, it probably would've worked.
Was the kill switch not checked at tech inspection?

Why didn't he ease out on the clutch, to put a load on the engine?
To try to kill it even?
Just asking

WOW! That could have been worse! (Ka-boom!) 😳
thanks for commenting!!
As it seems no one has given a definitive answer yet, at what RPM would that have been running? Thanks
they leave the starting line around 5-6 k that was a solid 7k
Rip 200k engine and turbo
its fine
The motor wasn’t destroyed

He put too much ether 😂😂
never enough haha
What the guillotine didn't work? Thats was scary!!
They don't know why the air shut off didn't work. It was very scary.
How many RPM was that?
all of them lol
@@yugotime1598 mhm
Name of the Tractor?
Gone
Did the sled p operater not pull the kill switch?
The tractor operator is to have access to actuate the air kill, AND a fuel dump valve, while in his seat.
Not everything works every time. They got it shut down pretty fast.
No wonder that it ran away... It got high on Ether!!!!! WAAAAY TOOO MUCH of that!!!!
no
