I have a Bunton 52" hydro WB. I use double blades, high lift on the bottom, Gators on the top. Does not have a mulching deck, and I blow the clippings out the side chute. Cuts very nicely in normal conditions, but when grass is dense or long, very little mulching action. I tried covering the discharge chute, but just caused a heavy trail of clippings along the edge. How to get a good mulch? What about double Magnums on right side spindle only? Any other suggestions?
