Moses, I don't think any of us have a definitive answer to the issue. The early 700/7000, 3300 &3400 series are in my opinion the prettiest tractors but it is hard to beat the old wide open hoods of the FDT's.

And I personally love the look of the later 7000's with those headlights, but it never failed even with two different engines (originally the 16hp and now a 12hp repower) that after about 20 minutes of mowing they will lose power and start to stutter. With the hood off, never a problem. I think especially without the deflector sheet on the engine blowing air down and out the front grille, that hot air hits the back of the headlights, recirculates between the engine and hood, and even gets sucked back in to go through the cooling system again. Only a matter of time before overheating....
Nice to see you getting some seat time again Jon! Is that the field at the showgrounds by your Dad's place?
My 716-6 had the same issue with the Kohler, but only when it was above 70 degrees or so. My buddy that took it off my hands has a chunk of 2x4 that he props the hood a bit with when mwoing in the heat. Just a couple inches does the trick for him.
i think youre probably right on with the heat shield thing... I have the same shield on mine directing the air downward thru the front grill... and the front grill absolutely allows a ton of air to escape... after mowing on a dry hot day it gets a good amount of grass dust collected there on the inside... I wouldnt have thought it would have been so much but it is...
