Question:
I went to my local Husqvarna dealer to buy a replacement blade for my 7021P. He sold me a 531 30 07-64 "premium mulch blade." Compared to the stock blade, this blade is somewhat beefier. After checking the Husq. website, I found that the proper part number for a 7021P blade is 532 40 67-12. Will using the 531 30 07-64 blade harm my 7021P? Also, I never use my mower to mulch. Thanks.
