This year I purchased a pecos ultra vac system for my 60"Lazer. I purchased it just for picking up leaves. I got the 5.5 hp brigs for the vac system cause the dealer didn't have the 6hp. Anyway, for some reason, when I take a swipe with it, the front right corner of my deck kicks out a spray of air or something that blows some of the leaves I'm going over to the right. If there is just one strip of leaves left, and I go over it, usually all the leaves just end up getting blown over a little and leaving another strip right next to the spot I just went over. It is especially bad if I go over a bare spot. It seems to kick out more air. There isn't too much problem on really thick turf. I was just wondering if anyone else has experienced this? Is it because the vac can't suck fast enough for the blade speed or because I should have bought the 6hp or is there something I can do to get a better seal to the ground for better suction? Any help would be appreciated. Thanks.
