It sounds like the PTO Driven Trac Vac machine shreds leaves as it passes through the pto driven turbine. KennyG I would have thought you would get better mulching of leaves with the deck down. I appreciate the advice!!! Keep the deck up for better mulching. I know on the website they sell an option to keep the 3pt part of the system up so when you lower the deck to suck up leaves your 3pt mounted turbine isn't so close to the ground but if it works better with the deck up then i can most likely not purchase that option.
