HeadleyJ,
I yakked with the Local Woods dealer today and thought of your post and asked. Woods dosn't make a small Flail chopper anymore, just the 10' monsters...and they ain't cheap. You could buy a nice used tractor for what they sell for new.
So on the off chance I called the local Landini dealer and asked what he was getting for the 6' Nobli Flail choppers...
You sitting down? 6K. Nobli is an Italian outfit that manufactures for themselves and several "Big name outfits" that just paint 'em green and slap thier stickers on them. There's video on thier site.

I gotta run south to get Ford/New Holland parts this week, and they usually have a used/rebuilt Flail chopper on the board, and they usually run around 2-3K. If I find anything I'll holler at ya.
Most guys around here run 'em to chop up pruned Blueberry Canes so the hammers get worn out, but there's not much driveline/gearbox wear on them from the light load.
If ya do it, it would be smart to just use it, then turn around and sell it for about what ya got into it, and then just maintain with the Brush Mower/bush hog and pre-emerge herbicides.
Gotta admit though...backing up to a stump and making it dissapear is FUN.

Stay safe!
