After a year or so of more experience, I still would like to see a better design for our uses. A few days ago I mowed a field of tall grass (5' timothy) with some brush and small trees starting to come up using my rotary cutter. Once again, I have rows of grass that didn't get mowed because the tractor tires mashed it down first, so now it's starting to stand back up and makes it look like my mower needs the blades sharpened, even though they're sharp. There are many times when a mower, both a finish mower and a rotary cutter, needs to be on the front of the tractor. I re-read my statement from about a year ago and still agree with what I said, which is "a smaller version of the New Holland TV140 would be the way to go." I guess some type of quick hitch would also be better than the 3pt.
Also, after hanging around at TBN for a while, I can see there are lots of folks like me that have a need to offset a mower to be able to mow over ditches and the edge of a lake. So, some sort of mower design that would allow this would be useful. But, it would have to be less expensive than the heavy duty side mount mowers the road commission uses.
