Here, in my area of the world, just outside of Portland Oregon, we usually use what is known locally as a "culti-packer" to crush clods and roll things down for seeding. Most pull one in front of the drill. Factories call them a "culti-mulcher".
Trying not to bore you with detailed history, after many years of study as to what causes some of the small seed crop failures, I had been able to attribute it to this tool. I renamed them a "aggregate segregater". We sold ours a few years ago after several years non use.
Well, now, after a few years of dd and no-till, we ran into a few issues with rodent control and not being able to get the soils to dry. So we bought a disk ripper and a disk. I have several fields open now that are disk ripped then dried some, then disked.
Having been opened somewhat on the wet side, which is normal for the area, we set ourselves up for what I call creating a rock patch. The wet clods, when the spring winds come up, can turn into rock hard.........soil rocks. Again, the details about opening up so much and/or why not culti-pack it before it gets dry, are a long boring story.
But once dry enough to plant, the soil rocks can not be broken with the roller. But IMO, after using a disk for many years and also using some vertical tillage tools, I think a disk with the blades backward may be the ticket to cut thru the larger soil rocks and firm the surface some, but not segregate the fines from the smaller soil rocks. This is what is needed to retain seed to soil contact in less than idea conventional tillage situations like this.
A crow foot roller would also be of great help, but are unavailable and for the 30' size, are very rarer to even find new. I can find 30' disk all day long in great shape for less than half the money and the rollers are usually 18-20" diameter where the disk can be up to 26". Or if one needed to buy new blades, and since it is not for cutting, if the frame had clearance, a 28" blade may work. IMO.
So in a nutjob,.....er,....I mean nutshell, that's what I wish to do. I can then also use this tool for seeding using my air carts.
