A lot of clumping problems arise once wet grass has adhered to areas underneath the deck, and it does not need to cover the inside completely, but only a buildup in specific locations. I think Micks was building up at the rear corner of his discharge opening. There are many decks that need to be thoroughly scraped every few hours in the conditions the southeast is dealing with. Once a deck loses its new paint, you can scrape the deck perfectly clean, make one pass in wet grass, especially crabgrass, and the buildup has begun once again, and it takes only a very short time until the deck is no longer performing as designed. A great deal of the annoyance you see with any mower clumping is coming from buildup problems. This is one reason I was totally confused when I saw the 472 begin discharging clumps immediately with a brand new deck that had new slick paint and zero buildup. Then when I went behind it in the same grass with the VX4 and it did not discharge the first clump, but only a perfect fan pattern that had the same uniformity in every square foot, I immediately realized there was a problem. I think this is a problem that can definitely be helped, but completely alleviated in my cutting situation, I kind of doubt. I started paying attention to the discharge velocity, and what GMLC was talking about when using high lift blades. The Gravely being set up the way it was would hardly blow grass off a drive, no uplift, and very little discharge velocity. The 472 with the baffle (don't know about without) would not have cut the signal grass I cut yesterday that was knee high, it could not move the grass out the discharge and away from the mower, just entirely too much to deal with. This grass would have really taken its toll on a 40 hp tractor and 6' rotary cutter. The 35 hp Kawasaki with the deck at transport height did not like its cutting situation in the least, but it did cut it, which I can promise not many mowers would. You folks deal with crabgrass which is probably your worst cutting grass in the north, signal grass is by far much worse. Signal grass grows twice as fast as any other grasses in our area, the grass that was knee high only had 16 days growth. Being around chicken houses where nitrogen is feeding this grass day and night, and all the moisture we've had is really pushing this growth. This is something no one in the lawn maintenance business should ever find the need to deal with, but in large area cutting on a farm, this is something I am forced to deal with, not something I like, but cutting that must be done. Most mowers would never move more than one mower length before the engine would stalled if trying to cut what I cut yesterday at transport height. I could have put the XR-7 into this grass at transport height, but had I taken more than 1' in the cut swath, it would have choked the engine immediately. This is basically like trying to cut hay (signal grass is forage grass) with a zero turn mower, not really something anyone should try. You can handle it fine if it is cut every 5 to 6 days, but with out weather that has been out of the question. I've never dealt with any cutting that's had the difficulty of what I'm dealing with this year, and honestly hope I never deal with it again. I would say; that according to records kept and it being 75 yrs. (1938) since this much rain was seen in our area, that I probably will never deal with this again. To say I had rather die than be confronted with this problem, well no, but if it's 75 more years, 139 is not an age I can see me blowing the candles out on a cake.
