I think he was inquiring about a 3pt offset disc harrow. As for 3pt finishing harrows, there are many nice ones on the market. The Monroe Tufline offset harrows are nice but can get pretty pricey. Everything Attachments has some pretty nice heavy finishing harrows if you're shopping new.

I think the Athens with the fold up feature would do some aggressive work. Ken Sweet

When I see harrow I think light disk, when I see offset I think heavy disk. Offset disk harrow sounds confusing to me but what do I know. There are several 3ph offset disks out there but I would much prefer a wheel disk.

I know that this isn't a 3pt disk, but I always like to peek at this set every once in awhile.
I like to pull it just one time! I'm going to get the Mahindra ...

If all goes as planned, I have a excellent John Deere model 100 7 Ft 3 point offset disc with scrappers coming in first of the week on a trade in. Ken Sweet

Probably one of the main determining factors in how deep a disc will cut is machine weight per blade. (Dividing machine weight by the total number of blades) Also, smaller diameter blades will cut better than large diameter simply because the blade acts as a wheel albeit a thin wheel. The smaller "wheel" has less floatation. Groundspeed is another determining factor; a slower speed will let the blades penetrate deeper.
Another consideration, which may not be as important on the smaller discs, is how good of a job of leveling the soil the machine does. Larger discs will have feathering blades at the outside end of each gang which tend to prevent deep furrows and/or ridges between machine passes in the field. The feathering discs normally consist of progressively smaller (an inch or two in diameter) blades at the outside ends of the gangs and sometimes the last blade will be a triangular shape to prevent leaving a continuous furrow that may cause soil erosion. Another important factor for doing a good discing job is the leveling of the disc frame front to rear which can be adjusted with the top link on the 3PH. Discs with wheels for transport and depth control normally have a self-leveling mechanism that coordinates the tongue angle with the lift mechanism for keep the disc level at any operating depth as well as in transport mode. It is very important than this self-leveling be initially adjusted for the tractor drawbar height as well as field operating conditions. Running a tandem disc with the rear gangs too low will tend to leave a ridge of soil behind the center of the disc while running with the rear gangs too high will result in the front gangs throwing up nasty ridges on each side of the machine which the rear gangs are not able to level out.
It is important when using a disc with wheels for controlling cutting depth to keep at least a little machine weight on the wheels in the field to assure consistent cutting depth. Raising the wheels clear of the ground will allow uneven penetration of the disc due to weight distribution. Some heavy duty construction type discs, on the other hand, are designed to run with the wheels raised above ground which adds cutting weight as mentioned above.
