I have been mowing all summer with my 52' Lazor HP w/ stripping roller. I mow mostly at 3.5'. It has been doing a great job for me and leaving my accts. looking good. This fall after reading about how well the mulching kit works for fall clean-ups, I went and bought one. I'm now cutting at 2.75" and I can't believe how nice of a job it does, my accts. look like carpet!! Here comes the question: Can I, and/or, does anyone leave the mulching kit on all summer? If so, how much does it effect speed? I have some big acct. and don't want to slow down. What about grass lenth? Any help would be great!!
