I bought a 20HP/52" model earlier this year, and it does a great job cutting my 1.5 acre lot. Has anyone experimented with double blades on this mower? I have a set of gatorblades ready to be installed for the spring, but I am really curious as to how doubles would work on this mower. I tend to cut my grass high in the summer (all sun), and I have an irrigation system. My main complaint with the mower so far has been that the clippings are a bit on the long side, and tend to lay on top of the lawn. Also, has anyone rigged up any kind of stripe kit for the fastrack?
