I bought a belt drive self propelled Troy-Bilt 21" self propelled lawn mower. The belt has broken 9 times in the last year and a half.
I finally caught on (after 5 or 6 belts)that the belt that sells for $18.00 at Lowe's can be purchased for $3.95 at most real hardware stores.
I also have a Troy Bilt push mower. It is a real piece of junk. Lowe's does nothing but say don't bring it back to us.
I am a slow learner. I also have a Trow-Bilt Tuffy spring assist *** eater. I can't say what I think about it here.
I will buy nothing at Lowe's again.
