I just picked up a mint condition 2010 ZD326 60" side discharge with 122 hours. I mowed today after about 2 weeks off (was on vacation!) and cut 2-2.5" off of 5" tall grass. The mower handled this with ease but left some serious windrows! My last mower was a Gravely 152Z 52" deck and factory mulch kit. This mower mulched awesome with no windrows and tiny clippings. My goal is to limit windrows and control clipping discharge from getting into flower beds and tree rings. Any suggestions on using the mulch kit vs. Gator G6 blades (without or without a homebrew blocking plate)? Thanks!
