Y'all might recall that I bought a new mower earlier this month. This morning I slung a belt, trying to push the mower past it's design specs. I took the old belt off and went to the dealer. Everything these days is make, model, serial number, but the service guy finally found a belt. Turns out it is a 1/2" X141.5" Now you know that and so do I.
That's the way we used to buy belts, by width and length, not by part number. Got home, changed the belt, then did a quick Amazon search. Sure enough, I found it. Linky here, for less than half of what the dealer charged me. While I'm at it, the belt he sold me is a Rotary Corp #12-14733.
I put stuff like this in the blog so I can search it later.
