I don't know why. But now I have a blow out problem I can't rid myself of. I think there has been a small change in the Gators I run since last leaf season. Either that or maybe my deck pitch is different than it was last year. I put on double Gators this morning. There was not a lot of blow away. But The blowout and fog of tiny leaf particals was a bit much for me. I removed one set and put a flat style highlifts on with them. The Gators have a drop down gullwing design rather than being flat. So the highlifts cutting edge is actually above the Gator's edge even though the Gator is on top. Now I have a blow away problem. I guess I have too much lift and air circulation now. It's a twin blade deck. As the left blade is picking up leaves, the wind off it is blowing the leaves away before the right blade suction reaches them. So, I'm going back to just single gators tomorrow to see if it's any better. If not I'm thinking of adding like a strip of rubber on to the front deck lip and letting it hang down. How far down do I let it hang? Would it help?
