VERY short lifespanThe end top sections of these blades erode away in about 6 hours of mowing! I've had the ZT1 42" mower since June, and I'm ready for my 4th set of blades and the machine only has 40 hours of run time total, much less of actual mowing. I don't have a rocky or sandy yard but it does get dusty. I can't imagine what is wearing these things down. The cutting edge is fine on each set, but they no longer lift or bag because the "wing" section is just gone!
