I have a pro turn 260 with the 29hp efi . I am getting a lot of clogging even in dry grass, some time's in the hose and other time's in the inlet of the vacuum. Some time's I get clumps were the vacuum meet's the deck . The belt never seem to be tight like the other brand of mower that I have even when new? I have also have on ordered ( 3 weeks a go )the vac baffle kit. Will this help push the grass threw ? I also ordered it to help suck up the leaves. One more thing I feel the bag's are put together cheaply, the plastic tube that holds the metal rings together do not work . They come apart and the bags fall of the mower a lot . On monday one fell of when I was backing up and I ran over it. That cost me over $100. Other than bagging system I think this mower is great.
