I ran my Scag WB with a mulch plate and regular blades for a year now and it mulches fine. My new scag tiger cat has the same setup but it leaves that strip of clippings on each pass. The mulch kit is over $300.00. Have you guys run a mulch plate with gator blades before? Did it get rid of the strip of clipping? Also, do gators bog down the mower at all? A lot of leaves falling these days.
