Just pulled a set of six gator blades out of the box for my 48" snapper. In inspecting them, I noticed the cutting edge on one was a bit blunt. I walk over and put it on the balance and sure enough, one side drops to the benchtop! I check the other five, whose cutting edges all look fine. Two of the six blades were out of balance! Have you all experienced this before? I have never before checked a new blade for balance.
