In tall,wet or thick grass which blades work the best? I use gator blades in the spring and fall. During the summer I use standard blades. But under extreme conditions I still get clumping of grass even with the gators. I hear alot of talk about running doubles. Can someone explain to me how you do this. (maybe some pictures also) I have an Exmark Lazer Z HP 23 horsepower. I am looking for an answer to avoid double cutting in some circumstances when the grass is long.
