infact, lets design two, a walkbehind, and a Z. list all the features you would like and how to do it. lets try to be sort of realistic (no flying saucer mowers allowed ). I will add my post on my perfect mowers later, as right now, it could turn out only sleightly shorter than "churchills history of english speaking peoples" . so lets hear about your dream mower, along with all the attachments you would want on it. you Z can either be front or mid mount any size deck/frame. same goes for the walkbehind, any deck size. don't be constrained by the simply conventional methods of building mowers, when you think of a mower, think of the job(s) you want it to do, then figure out how you will do it. for instance, if I wanted a very light mower, I could trim the weight off by having the frame composed of composites, instead of steel (which if steel prices go the way they are, it will probably be cheaper to use the composites anyway).
