I feel just like tommy, I'd take the oversized tires off and hand the machine back to them, and tell them I want a NEW unit now. I wouldn't accept no less. I would imagine you have insurance.
Second the motion for installing the original tires back on.... That would be a big plus !!!
Third, if for some stupid reason they don't give you a new machine, are they going to give you a machine until the torched one get fixed....
I swear, I would of let the thing burn to the ground, for I've known of to many pieces of machinery that was so called " fixed " be trouble for the life of that machine.
DEMAND A WHOLE NEW UNIT, LET THEM FIX THAT ONE, AND THEN THEY CAN SELL THAT ONE FOR A DEMO MODEL !!!!!
P.S.
Make 'em replace my dern GPS SYSTEM ALSO, sorry, but this situation just makes me sick, and it isn't even my machine... I know what you are going threw, went threw it in a pick-up truck years ago, and when it was so called fixed, it never give me nothing but trouble since, then it cought fire again, and let it burn slap down to the ground that time !!!!!! And Then, only then, did I get a truck that was suitable to live with. Matter of fact, still have it, use as a farm truck !!!!
