I have a Cub Cadet Commercial Z with a 48" stamped deck. It leaves an uneven cut where the front wheels have flattened the grass. I run with the throttle wide open, have tried running a slower ground speeds, have sharp blades, and a level deck. Two different Cub Cadet dealers have said that the deck isn't deep enough (about 3.5" deep) to get the lift needed to raise the grass back up to cut it evenly. One dealer offered to sell high lift blades but warned that I might get lots of grass blowing out places other than the normal discharge shoot. This is already happening with the stock blades. Grass blows up from the front of the deck, filling the area under the deck covers with grass. The following is from Cub Cadet's website. It is answer to a question about uneven or uncut grass: Overlapping may be insufficient. The tires push down grass during each pass. If you line up your tires with tire marks from the previous pass, the grass does not get a chance to stand back up during either pass. Overlap more than the width of your tires on subsequent passes. This will allow the blades to draw up the trampled grass from each previous pass and should produce a nicer looking cut. As far as I can tell, this means mow twice, cut once . Is this a normal expectation for any stamped deck? Stamped decks have been on homeowner mowers for years. My previous mower, a Case 220, was no better as far as a quality cut. Any comments or suggestions?
