I've heard about them (and lusted much after their 28HP Caterpillar diesel AOS model) but NEVER have I seen/or heard of someone using one of theirs. How is the ride? Cut quality? Durability (has four 11 gauge frame rails-enough? ) Longevity? Relibility? Yes, this is my first post here. I have been over on Lawn **** but DID meet some "interesting" people. FYI, for the past 2 summers I have worked for a Lawn care company in the DFW area that services many large commercial and residential yards. They used Toro Z-master gas and Diesel mowers, Stilhl/Redmax trimmers, and stihl blowers.
