I bought this mower last May (2015) and in June of this year, the belt that drives the blades shredded. I thought it was a freaky coincidence that it did this being so new, so I just bought a replacement and went on my way. Just yesterday, I was cutting my lawn (1/3 acre) and it shredded again. Is there any good reason this keeps doing this? I thought I had it adjusted right as far as the tension for the belt and can't think of anything else causing this. Has anyone else had this problem with this same mower?
