I am running the Ultra Vac on a 66" Triton deck, and am getting alot of blow out of grass coming out the front of the deck. Its not much of a problem when out in the grass, but when coming up on driveways and sidewalks it puts alot of grass on them. It seems like it should be sucking the stuff up better. It has the stock blades, and I have the front baffles adjusted down so there are 2 holes showing in them. (about 1 inch down). I already lowered them a bit more then a half inch over what it came set at. Should I take them lower? Is there any bad side effects to lowering them farther?
