I've got a Deere 485 tractor that has a new 62" "Edge" deck. It blows clippings out the front nearly as much as what comes out the chute. They blow up all over the deck, onto the operator's platform, all over my feet and legs and clog the outside/first pass radiator screens within a couple of hours. The deck is level with a slight tip down in the front (about 1/8"). It is new this season and has not gotten any better with drier grass - in fact, it has gotten worse in the drier grass. I clean the underside religiously (every second mowing) and in spite of that, the buildup under the deck is horrible from week to week. The clippings that blow out and up onto the top of the deck are an inch thick or more by the end of mowing just one time (about 2+ acres). They fill up the area beneath the pulley shrouds and I have to remove the shrouds after each mowing to clean under them - they're so thick that compressed air will not blow them out! What is wrong, here? Is this an inherent problem with the 'tractor style' mower decks? I had a JD 777 Z-Trac and it did not do this (wishing now I had it back). I would like to enjoy the benefits of a tractor (more utility around the site) but not for this hassle. I talked with my dealer and he suggested Predator blades (Gator). So, I'm installing them this evening but honestly, I do not think it will help and with even smaller clippings, it will probably make matters worse. Arghhhh!!! Help? Or, should I just trade out of this unit?
