The reason for the trays on top was to hold rocks so that the weight would help push the disks into the ground. Note that the edge of the field provides plenty of rocks to use. That poor farmer was like my Grandfather --- after he started working another farm, plowing was slow because he spent a lot of his time carrying away rocks that the plow had hit. And evidently freeze-thaw cycles would push more rocks towards the surface because it took a few years before he got the fields clean of rocks.

Here is a series of pictures I took of a disk at the John Deere dealer where I got the brochures. I introduced myself to a dealer, and he spent time with me even though I was up front about I would not be buying anything. In fact, he suggested that I help myself to as many of their brochures as I wanted. He also taught me that primary tillage was done in the Fall and secondary tillage was done in the Spring.

|The more I looked, the more rams I found. The two on the sides fold the outer wings onto the middle wings. The one by the staggered wheels helps raise it out of the ground when making the turns at the ends of the field.|
|John Deere has you pull the reels behind your disk or cultivator. You can tell this is newer technology because the terminology is still in flux. John Deere talks about "rolling baskets" instead of "reels." The reels put the larger soil particles on top and finer soil particles in the seed zone. If you look at the second picture of the Kuhn Krause posting, you will see clods being flung above the soil so that they will land on top. I suspect this device works well only at the higher field speeds of modern, high-horsepower tillage of around 10mph.|
