Today I installed double blades on my Toro Z 62 SFS Deck. I have the high lift blades on the top and a set of Atomics on the bottom. I mowed for about four hours using the double blades. I stopped several times to make sure the blades were in a perfect + pattern. They were! The cut using the double blades is drastically improved and the striping is excellent considering my previous posts re Toro Striping kit. The only thing I dont like about the double blades is the Atomics really pulverize the grass blades, which creates more grass dust than I am use too. The other dislike is the increase in noise the double blade set-up makes. I give the double blade set-up a 98.
