I own 2-21" mowers, both registered. One is self propelled, one not. One unit cuts centipede grass, the other zoysia. I have tried every trick in the book to solve my uneven grass issues, ie mohawking, striping. These would include, height adjustments, new high lift blades, mowing patterns, mulching-side discharge-bagging, cutting slower, correct wheel alignment, very sharp blades. Nothing has worked with either mower. I am in the plastics business, know alot about Xenoy decks, and feel that this filled PP deck does not have enough inherent strength from the plastics selection or design. I believe the motor is causing too much of a load bearing issue in the center or the right side causing the deck to raise on the edges. Also could be warpage, in my business, they don't call it "polywarpylene" for nothing. Could be EGO bought a bad lot of plastic decks already warped in 2016. I am very frustrated about the whole thing, they could have spent a few more bucks on a stiffer Xenoy type deck, but they cheaped out, although they command Honda type price.
