I've popped a couple tires on my woods rear finish mower too. The dealer told me he only orders solid now from Woods. You're not alone. I'll trade mine in before I throw another $400 in it for solid tires.
It took only 66 hours, less than three of them, mowing, for the whammy to get me. This is Crazy Week, getting the disc golf course ready for our annual tournament, the FernBurner. I'm doing the last mow and everything this week is under the gun. So, of course I get a flat on the mower and to make it better, two of the eight wheel bearings I put in had seized, on different wheels of course. I'm in for a late lunch. Late from fixing a flat and freeing up the bearings, hoping the expensive little buggers will be okay.
Oh yeah, it was a tiny puncture in the tube. Not a new one, but the patch I'd put on it was missing. It probably left when the bead came loose. I patched it again and gave it 50 pounds.
interesting about Bush Hog doing the same thing with solid tires. I'll probably get through this mowing season and consider trading up this winter when things slow down.
I got my used ATH 720 six years ago for $425. The guy I got it from paid $1200 new. I think they are over $2500 now. A new one would be nice. I'm getting a lotto ticket tomorrow.
