Query: Built to Fail

This blower has a plastic engine mount that is held on by 4 self tapping screws that are screwed into plastic. The screws back out and contact the impeller and eat through the platic wheel causing the catastrophic failure of the impeller. The two parts involved are about $30.00 but Troy Bilt would not send replacements because I did not have my original receipt. Even though the serial number proved it was manufactured in 2009 they would not stand behind this obvious defect in manufacturing when all I asked was for the replacement parts and nothing more. Don't waste your money on this product, it is designed for failure! I will never buy another Troy bilt product.
