Loader Flipped my L48 Kubota

How does one cut off the fuel supply on a tractor? I thought shutting the key off would of done that.

In a normal situation my key cuts fuel flow. But there is a manual cut-off at the injector pump also.

Grasshopper, some machines have key-off-fuel solenoids, others have mechanical cable or lever operated fuel shutoff, including dump throttle models. All should have a valve on the tank outlet though, with some exceptions.

So is that what OP did you think, shut the fuel off at the injector pump. Next time I look at my tractor, I'l see if I can find that manual shut off.

Mine are on the dash. Most are pull buttons. On one the hand throttle has an extended stop position.

Permatex makes a nifty head gasket spray. I use it on both sides.
I would have reused it with coppercoat. It would not leak then. I haven't put a head gasket on without it after a co-worker at a car dealer told me about it. My buddy uses the $1/can aluminum color spray paint because he thinks coppercoat costs too much.

I would not have known where mine was or that it even existed without reading about it here on TBN.

It's easy to think one could kill the air to a Diesel engine after it has flipped over but in the heat of the moment things are happening fast and finding the air intake or manual fuel shutoff can be a daunting task when you are upside down.

I think a quicker way to kill the engine would be simply to plug the exhaust system as most are accessible easier than the intake. A pair of gloves or any way to try to tightly plug the exhaust. If the system is tight enough it should work.

Maybe practice it a few times on your machine to see if you can stall the engine at full revs.

Fred, hoping never to tip over.

driveway, are the head bolts stretch bolts? How many times can you reuse them?

if it's laying on the side of the air cleaner and intake manifold, it may be difficult.

A large ball valve in the intake might be good for any diesels running around escaping fuel gas ( lp, methane, etc.. )

You would think that. And that's what i thought. But turning the key off did not work. Luckily, the L-48 has a manual fuel shut off on the filter head so you can turn the fuel off while changing the filter.
