...61"/25hp Kaw. I was impressed with the suspension, definelty makes a differance in the ride. I also really liked the hydraulics, nice and resposive. The quality of cut was o.k. considering I was mowing at full speed 90% of the time. I was wondering however, whats the longivity of the suspension, after 1500 or so hours, how does it hold up? Also, Ferris owners, what are your expiriences and opinions good or bad. Thanks!!
