First have to say this is a great mower. Did alot of research on mowers and demoed a few before I picked the super Z. Best money I ever spent. A couple things I did was I put some anti-scalp rollers on the underside of deck. The deck would scalp on occasion only on very uneven ground. Now it doesn't scalp no matter how uneven the ground is. The second thing I did was that I had a buddy of mine make up deflector plate that I can raise and lower to control flow of clippings. Simular to the deflector plate that is available for the Exmark mowers. If anybody is interested in how I installed the roller set up or the deflector plate please feel free to e mail me. Thanks Cliff.
