This is as I've already mentioned, a totally different grass type, one which appears to be very fast growing, with more of the growth moving in a horizontal; instead of vertical direction. My deck set in the # 4 position (as Green stated) is cutting at 2 1/4" (57.15 millimeters), meaning he is probably cutting in this same range. Looking at the photo of the Dixon cutting the same property , but with probably less moisture, the only difference is the Dixon deck is processing the clippings into a smaller form. Like with an Exmark Ultra Cut deck that also processes the clippings into a shorter size; it gives a better look than will a tunnel deck that is designed to process more grass, but in a faster method. The longer clippings produced by a tunnel deck are much more difficult to hide, this is only common sense. You can still see the mat of clippings in his photo, but because of the smaller size, the cut area looks better. The longer clippings, with moisture added into the equation can also promote the dropping of clumps, as seen in many photos of your area. I have never seen anthing even close to resembling this, and I cut Bermuda, Kentucky Blue Grass, Fescue, and a mixture of Crabgrass and weeds, but do cut on a 5 to 6 day rotation when necessary. The more grass, especially moisture laden grass a tunnel deck needs to process, the more problems you will incur. You can take a Scag Velocity Plus deck, cut the same areas you are having problems with, and you will see the same type mat of longer clippings, but not as long. The reason the Scag cut will look better to the human eye is for the fact it processes the grass clippings into a size between the VX4 deck, and the Exmark Ultra Cut, or Dixon shown in the picture. It takes very little size difference in clippings to make a finish cut look completely different. What I can gather from everything that has been shown and talked about is, the VX4 tunnel design deck will never give that further processed grass clipping look; while cutting your faster growing, moisture laden type grasses, in what appears is normally a more damp, tropical type region. I would like a question answered, what percentage of your cutting gives this type problem? If I had to guess, I would say the dryer periods give you much less problem, cutting in the mid to late afternoon gives less problem, and cutting on a less than weekly basis (not feasible, I understand) would give less problems. Would this be a correct assumption? Would everyone agree you can still see a mat of grass clippings, but due to being smaller, they are much less noticeable?
