I have a problem with this bagger. When cutting more than 2 inches it leaves clumps on the discharge side. I then have to go back over to suck them up. I have called the dealer, the factory and asked evreybody nobody knows. Hears is what the factory says you are taking to much off. I hate that answer. I have sharp blades, The machine is at it peak rpms, I have cleaned the bagging boot out, and the deck is clean. Can anybody help with this frustrating problem? or is the fast vac just a bunk bagging system?
