At least you have a chance I was plowing with sweeps behind me that got caught on a root and broke, tried backing up to get the root to release and backed over the broken sweep... cut a 12 in slash across the rear tire.
Called dealer (semi-rural area) I use for tires and said I need a R4 for my Kubota tractor, he was like R what? Took the tire over and he took one look and said oh you need a skid steer tire.
