A couple of questions come to mind:
Is the engine compartment sealed from underneath, or at least somewhat closed off? I'm thinking that with the radiator perched up there, it may stay cleaner than the previous designs if most of the air gets sucked in from above. I don't have a cooling problem with my 'C' but with the caveat that I can't mow longer than three hours or so without stopping to clean the radiator. If I don't, it can still overheat. It would be nice to be able to mow the whole six or seven hours without stopping.
With the nice rake of the engine cowl and how far out the 3pt hitch sticks out, I wonder if it would be possible, with a high-mounted car-like rear view mirror, whether you would be able to get a good enough view of the 3-pt hitch work to the rear without getting a neck ache from turning around all the time? Now that would be a major improvement!
I see how they're handling the tool storage area. Not as roomy as the tilt bed, but a great improvement over what's available in a tractor.
How about some pictures inside the unit? I'm particularly interested in how they're handling the 3-pt hitch lift control and where the TNT controls would be. Which reminds me of another question. Have they thought about controlling the TNT controls from outside the cab when connecting an implement? I'm thinking specifically about extending and adjusting the hydraulic top link to push the pin through. I use the Pat's Easy Change, so grabbing the lower links from inside the cab isn't a problem.
