THis is the best design for a mower on the market - beats swisher and other brands hands down. Buddy had Swisher and another lesser  unit .. .  kept tearing them up (junk), he is hard on stuff . . cutting small brush and tall canary grass in mud, well he has had this Kunz one and it does a much better job mowing and handling brush. The deck angled back, must have something to do with why it cuts better, faster and handles brush better then the others. Highly recommended . . . http://www.kunzeng.com/
