What do you guys think of the Great Plains Solid Stand 30 double disc drills on 7.5" spacings ? Are replacement parts terribly high on these drills? Do they have the down pressure and the clearance to go through milo stalks? Would this be a good set of drills to own? Long lived? I just don't want to purchase something like this, only to find out after the fact that they are not all that great. . . TIA for the help. |
