I have a 3235 cubby with 60" deck / 25 hp. I have tested the Z / super Z, dixie chopper / exmark 23hp which my brother bought new this year and loves it. now i am new to zero turn mowers, the exmark my brother has seamed to ride rather smooth in his own yard. The hustler Z / Super Z i demo. in the dealers lot, yard or what ever you want to call it seamed to me to do alot of bouncing, rough in other words. Now I'm not running down this FINE looking mower because the super Z is the one i attend to buy. Do most of these mowers ride rough or is it just me ? I don't see how anyone could mow at 10-15 mile per hr with these mowers bouncing up / down. Is there a secret to making them ride smoother ?
