OH Man ,, I have had a few ,.,.my 4020 diesel has burned wires twice, all by itself ,,watch out for battery chargers and coolant heaters ,. had a few fires from that junk ,. , bak when I was in school, I rode on the back of the ihc 203 with a fire extinguisher , one very dusty year ,, it caught fire a dozen times or more .. just could not keep that dust away from the holt motor,,. my brother and I lost a 510 massey 30 yrs ago , that was probably the worst personally ,neighbor lost his 6620 jd in my field, had a problematic latch on the door,but he got out,,. set the oily shop floor on fire with a pc of hot steel ,numerous back fires under the car hood ,, no biggy , threw my coat over them , that smothered them out,20 yrs ago my 850 nh roundbaler started wrapping twine on the main shaft that is covered by the box shield ,.,. I was rollin corn stalks,. and the pikup had all my attention until i saw fire ,,kept going till the bale was full dropping little flamelites along the way across the field , so that it would kik out , kikt it out on fire , let the bale burn , and went back running don the flames with the tractor . most recent fire was a roundbale tipt into the tire and started burning
