I am relatively new to using a zero turn mower and have lots of questions. My Cub Cadet is a ZRTS1 50" and I use it to cut a 1 acre parcel. It makes cutting this parcel so easy for me since I only have the use of one hand. The one question I have right now is when I am cutting new grass this year my mower clumps up the grass and tends to dump it when I cross my sidewalk area. I am cutting initially at 4 then my second cutting is about 3 1/2. Should I cut at 4 for both cuttings until the weather gets warmer and grass tends to dry out more? Like I said, I am relatively new at a zero turn, and need a lot of advice from the ones who are old hands at this.
