that works just as good! lol there were a few that only offered the electric kill also

I thought all the 3510 and 4110 tractors had the manual shutoff?

Sorry 4010 all 4110 and even 4510s had pull kill...

I wish they sold the kits so you could put those old tech shutoffs into newer tractors and toss the solenoids...

LOL that's no lie! I guess they needed to use the space for something else

Just another thing to jack the prices up with.

If you have ever had a diesel engine "run away", you will be willing to stop the engine at any costs, before it grenades! Last one I had "run away" was with an automatic transmission that required the truck to be at idle before it would engage into gear, so popping it into gear to stall it was not an option (although I tried). Had to stand there with the keys in hand, and watch it wind out so fast I thought it was going to come apart before it finally decided to shut down. Never any fun!!

put in high drop the loader in the ground and let it have the full forward pedal

The diesel engine in question was in a tractor trailer, with an automatic that required the truck to be at idle before it would go into gear. So... no loader to drop, no full forward pedal to let it have.
If the seal between the turbo and the oil that cools it goes out, then the oil will be sucked into the turbo, and atomized, so basically the engine starts running off of the oil that is coming from the seal and the more oil that comes in, the faster the engine runs, which causes more oil to be sucked in, and it becomes a vicious cycle. Typically you have to choke the air intake, or starve the engine of fuel, or stall it. If you can't stall it, and it is feeding off engine oil, choking the air flow is the only other option.

Yup stoping the air flow is the only way to shut down one sucking oil from the leaky turbo seal. The VW TDI engines have a ASV valve. It stands for anti shudder valve. It's a valve in the intake that closes when you shut the engine off. It stops the air flow, thus stopping the engine quickly not letting it rumble like the 80's diesels did for a couple seconds after you shut them off. The ASV valve in theory would kill a runaway VW when you shut it off.
