I have a JD 2305 and have about 3/4 acre to break up for seeding. I'd welcome recommendations on a disc as the only models I've discovered are KingKutter.
I doubt a disc will break up your ground, and you will need to get rippers in there first. After the ground is either ripped, sub-soiled, or plowed - then the disc will work up the dirt for seeding.
A disc might work if the ground was plowed last year and in a crop such as beans or silage corn (no stalks remaining).
There are too many tree roots around (as this is a yard, turned paddock and now going back to a yard) to run anything too deep. I'm fairly certain that a notched disk will be fine. In areas where I need something a little deeper, I'll probably drop the teeth on a box and plow a little.

Tractor supply are now carrying "Farm Force", which look suspiciously like KK to me, about $850.
Sundowner have an 6 1/2 ft 18 inch diameter disk for (list) around $1250.
FWIW, etc.
Landpride makes them also, here is their website. Landpride
There are several manufactures of disk harrows with light, med and heavy duty frames, the box frames with adjustable harrows look to be the best built.
