difference in ride quality? I am demo-ing a Mini Hustler this weekend. Tried it out on a small patch of turf and it mows great. I do have some fairly rough terrain (pine tree roots, crawfish mounds, and yard has not generally been taken care of -- ruts) With any speed at all the mower is beating me to death. Will the suspension seat help and/or is it available for the MiniZ as an add-on. I know the Super Mini comes std w/it but I need to keep the mower width to 52" - 60" is too wide!!
