I cannot believe we waited so long to buy the mulch kit for our new Craftsman mower. Complete game changer. Mowed the grass after we got the blades installed, perfect! Absolutely perfect! We had to call Sears to send a technician because we did not have an impact wrench to remove the blades. Blades would not come off without an impact wrench. Anyway - looks like a craftsman impact wrench is on my hubby's Christmas wish list now! Highly recommend switching to the mulch blades for mowing the grass. We are happy with this purchase and would recommend it to family and friends.
I ordered this as the part number says it is for the new mower I just bought. It is a part listed as compatible with my mower. The picture shows 6 point star. However, after I removed the deck and gut the flange nuts off, I went to replace the regular blades with the mulching blades only to find out the mulching were 5 point star instead of 6. So they won't fit, and since I procrastinated a few weeks to take the deck of my new mower to install the mulch kit, it's now past the return point.
The man that delivered the mower told me that the mulching blades had already been installed on the mower. When I mowed the mower would clog up and leave large piles of grass in the yard. I got the box that came with the mower which I really didn't know if they were the mulching blades or the original blades that came with the mower because they both looked exactly the same. Never the less I put the blades in the box on the mower and still had the same problem.
