I have been trying to cut my lawns a bit higher for the summer due to the extreme heat. I find with the fusion blades in good growth that I get alot of uncut grass if I try to cut at 3.5". I get a better result at 3.25, but still misses quite a bit. Now I mow in a mix of cool season grass, and have been experienceing good growth. Most of the missed grass is not apparent unless you run your hand through the grass, or have to blow some surface grass with a blower. The blower reveals the fact that the deck is not getting great vacume. I read where if you want to cut tall stringy stuff you should move the front baffle down and drop the blades with a spacer you will cut better. What about on normal grass in medium to fast growing conditions, is there a baffle setting, or blade setting that will give better performance? It looks like I have barely any forward pitch to the deck, pretty near level to maybe and 1/8" forward pitch. Would the blowout baffle possible help? Do you have a part number for a 60" blowout baffle on a xr-7 Super Z? Any suggestions would be great. At present it is not cutting as clean as my old Super Z. Thanks for your help.
