Between that and the DEF system

Def burns?

Usually once the fuel lines burn off its over.

D8 at work, we have a manual fuel shutoff valve. And a fire suppression system.

Those two things probably would of saved it.

Shut tractor down in safe spot.

#1 if the auto fire suppression didn't go off already, manually set it off.

#2 shut fuel off

The DEF spraying into the SCR system isn't so much the problem.  It's the DPF that gets much hotter, especially during a regen.  They can have runaway regens and the core basically turns to lava.  

Lots of times these are a hydraulic leak spraying on an ignition source.  It's why they use fire resistant fluids in so many critical hydraulic applications.

I should have worded it differently,  I just meant heat generated by the system in general.

Yeah, kinda what I meant. Definitely system gets pretty hot and who knows what kind of tree/grass debris on a groomer tractor
