I have heard some people suggest when doing leaf removel to combine both types of blades. The setup would be for a 3 blade mower. Use two gator blades and use a high lift blade closest to the bagger. The idea being more lift at the bagger than grinding up of the leaves, resulting in less left on the ground either for another pass or to be blown off the lawn. I may have missed a thread on this previously but didn't see any in a search, any thoughts or suggestions would be great?!
