Yes there is. Look online and you'll find many other manufactures that produce blades both harder and more durable than the factory ones supplied.

Not mowing too fast just not correct blade material. Ask any metalurgical engineer and they'll tell you the blade material should be chosen based upon many factors and hardness is critical in this one. The blades they have chosen to use are not hard enough to stand up to what they have chosen them for. I mow the same grass at faster speeds in both ground covering and blade tip speed and don't have this problem. I'm not blaming the mower but the engineer or material supplier for not researching clearly enough what the correct material necessary to mow grass is.

My BZ5426 mower with 6.2 hours has the exact same problem. Called my father, who is a metalurgical engineer, in Pittsburgh. Quite simply the blade is not of sufficient hardness to be used for what they are trying to do. I looked on the web and there are thicker and much stronger blades available. I also mow my yard with a Rhino mower deck that after using all last year needed the blades sharpened and they did show signs of wear but they did not fall apart like the factory Husky's did. He told me to stay away from the factory blades unless they come up with a harder material the ones supplied are outright dangerous to wear that quickly and he said if they checked the hardness on the blades they would most likely find the material not up to spec of what a normal metals engineer would recommend. I love the mower but am sadly disappointed in the choice of blade material they have gone with and then not doing something to correct it. I went to Lowe's where I bought the mower and was told that was a normal wear item. I told them I agreed but wearing completely out in 6.2 hours was not wear but defective. The manual suggests sharpening/replacing the blades at 25 hours, I'm not 1/4 of the way there yet. Something doesn't add up.
