I don't think you quit get it, the old Super was asking to much out of the wheel motors and it created a problem. The chasses on the Super is made as good or better than anything out there. What makes the chasses so good is how simply it is designed. The mower is running 15 MPH and that is much more demanding on a machine than going 10. If you can mow at those speeds the mower more than makes up for it in profit. Where I am with a new PUPPY HD in 26 inch wheel trim on big accounts at 16 or 17 MPH it will just leave the Kabukie sitting there trying to figure out what happened. Don't get me wrong I can still worship the Kabukie God but the Kabukie God is slow. It will leave a Gravely sitting there as well, Puppy is the Hustler God and should be respected as such and worshipped as well.
