Very good quality and durable.
I only used this blade for 15 minutes so I can't say much for now.
My daughter and I are so thrilled we could purchase these blades as an extra set, right at out little local Sears store. So now we have an extra set which we can rotate out when the. Blades need sharpening. These blades are a great bargain and hold up well, and since they are a mulching blade and we don't have to mess with the bagger..so my lawn gets mowed all the time and it's really fun riding around, mowing while getting great bikini tans and sipping cold lemonade!
Tough steel, made for sandy conditions for longer wear.
I have changed 20+ lawn mower and tractor blades in my life, never had one that was this difficult to put on - I cannot figure out why one blade is continuously cutting at a different height from my 42" craftsman tractor. I put the old factory ones back on and they worked perfectly, not sure why this set seems to cut lower then my OEM ones? They do make a difference though cutting through thick grass and lots of leaves
nice blade good even cut
