To start with I took my spare trailer tire to see why it had a bulge on the side wall. It had one about the size of a foot ball on the inside also. Never seen that before. Bought a new tire. Got to my mowing job, after a few hours I had a front flat, but I had a spare was going in a short time. Then the big problem happened. The front mower lift arm attaching bolt broke off at the axel housing. With less than a hour to go I finished the mowing dragging one corner of my mower on the ground. Now I have something to do next monday. I almost forgot it's my birthday today.(67) Hope you all have a safe 4th. Stan
