Hi folks: I have a new ZD18F with the 54" deck and my cut doesn't seem to be very efficient. I do a couple of passes and I notice a strip of grass blades weren't cut. I've read some other posts in here about Kubota's stamped decks but this just doesn't seem right. It's especially bad when I'm mowing sideways on a hill. I take it the deck isn't designed to more or less float over the terrain? I think I have my anti-scalp wheels set correctly but not sure. Any suggestions? Thanks in advance.
