I shot a bit of video of the old Crown rotary rock picker I use to pick the rocks that turn up on this farm. Its not as strong as a Degelman but still gets the job done for me. Has picked a lot of rocks over the past 35+ years.

In other news; as dry as its been, I still managed to get a tractor stuck today. Seeded a creek that had dried up for the first time in years. Seeding went ok but when I went to harrow pack it with the 2090 those single tires did not have the flotation to pull that harrow packer through without getting stuck in the only soft spot on the field.
