I have started in this business for extra income this summer. I have been using a 36" Bunton Hydro walk-behind with a sulke. I keep my blades sharp and cut 7- 10 days. I have been reading about guys using 2 blades per shaft and some of them are the Gator blades. Does this improve less noticable grass clippings or make a side discharge a mulching mower? Some imput please.
