A little late with my reply but years ago while back filling a trench, in the dark, I ended up upside down in the trench with my little Kubota. After getting out of the machine & before shock took over, I extracted it as I had a gin pole truck & a back hoe really close by. After it was sitting upright I was getting a little "jumpy" so I went to the house & had a couple of good shots & supper. Went out after about an hour, started the machine & it smoked for only a few seconds & was all good after that.
I will add that the machine was shut down as soon as I felt it sliding into the ditch
