Just installed my mulch kit for my Ztrak. I used it on one lawn today. It works wonderful. I am going to love useing this. Only thing, I used the mulching blades that came with the kit. They dont have a very high lift on them. Tthe lawn i used it on is a kinda shi-- lawn. Hope when i use them on my real nice lawns they mow as nice as my high lifts. Any comments?
