I agree with Lazer and Jaybee, what I was trying to say is, it may not be the mowers fault. Evan has said in past posts that his Z Master cuts wet grass perfectly, but I saw the same brand clumping, so it must be something the operators were doing wrong. The grass they were mowing is right across the street from where I was mowing and right next to another lawn we mow. They might have been cutting an inch shorter or something like that when they should have been cutting at the same or higher than the previous week. I have no idea, but it wasn't looking good. They might of had a deck that was completely clogged up too. I agree that I could make any deck clump up a lawn if I wanted to. It's just that some can't make a lawn look good, in any conditions.
