We have one that has 6 shanks on 26" spacing.

Doesn't leave the ground as level as a CIH 870/875 but much better than DMI 530/730 and it's way more adjustable to conditions than a JD 510/512


I think it does a fantastic job for what it cost to buy a used one.     

Only complaints is that I wish we had the coil springs on the shanks and it really should have tandem lift wheels.   Someday we'll probably put bigger tires of some sort on it, its too much weight for the 2 implement tires that are on it.
