As mentioned, post info on your flail in that flail thread. There are some flail snobs there and yours might make them a little more humble!
Interesting that it's that light (weight-wise). My pocketbook had me looking at a Chinese flail that was 88" and weighs over 1,300 lbs:

If I knew that the flail that I was looking at could hold up to 1 1/2" brush I might lean in that direction. Right now I'm leaning back toward a higher-end rotary cutter: lots of brush to go after. My conundrum is that as I clear I have more grass to mow and need a more efficient mower (until I can get animals to do it for me!).
I recently got a dump trailer (used 5x10

Will be towing that with the new tractor; going to be hauling a bunch of material/fill (from just up the road).
Speaking of towing, what's the best way to get a ball on the NX drawbar? Are there receivers that one can put on it, or just direct-mount the ball? (Pintle hitch would likely be best in the long-run)
