I have been using three high lift blades on my walk-behind, but the bagger packs a lot better when I use high lifts on bottom and Gators on top.
Peter is right about the blowout and what works best on any given deck.
I may try Gator blades on the left and center spindle with a Gator and high lift on the discharge.
Let us know when you find out what works best for your deck.
Be Honest and Trustworthy and give thanks for all you have. Life is good.
