I have 2 super Z's and after owning these for 6 years and learning just how much potential a ZTR has to mow grass this is what I believe somebody should build. My Super was a great design platform wise but had some shortcomings but with newer hydraulics becoming available and more motor options I have come to the conclusion this is what should be available for the real tough job's. Using a basic platform like my standard Super which has a real low center of gravity which is real important to me someone should take such a design and truly finish it right! The Mega mower would be this, if possible a heavy duty 2 speed hydraulic drive. 1 speed would be torque for climbing hills which would top out at like 8 to 10 MPH and you could lock it in position with a lock to keep employee's from hot roding,I am serious and 1 speed for blasting flat open areas out that goes like 15 to 18MPH.. Then the motor would be a water cooled fuel injected gas vertical shaft V twin or v 4 ,no diesel to heavy but maybe an option. A gas motor of around 1200 to 1500cc that makes 45 to 60 HP. Dual blade drive belts stacked on top of each other so there would be no slippage of blades,Bigger wider tires on the rear with a dual wheel option for rear. That is in my opinion what somebody needs to build to take these things where no man has boldly gone before in the area of Grass Trek!
