I have a LawnBoy Silver Series mower, with a B&S motor. Using the factory blade, I took off the Mulch fan. With it on or off, it cuts like crap and I want to improve the cutting on it. The reason I bought it is because it has the front side chute. I use it on properties that have hard to get area's where I can't get a WB in. But at 3in height, it sucks. Any reccomendations?
