Farming in California in the 1950's and 60's we used a somewhat similar tool we called simply "the roller" both for seedbed preparation and to firm up after planting row crops.
It had alternate wheels and toothed disks. The wheels were cast iron, with a flat surface maybe 2" wide, but with a thin raised rim in the center, projecting from the flat rim maybe 1 1/2." Those ran on a steel axle, but I think were not very tight on the axle so they could move a bit. Between each pair of them was a narrow, maybe 3/8" in thick, disk with the outer edge toothed, maybe an inch deep. They ran on the hub of the adjacent rollers, but with the center hole much larger so the floated freely.
Ours was three sections, the center maybe 8', with a pair of 4' ones on either side drawn by outriggers on the center unit. Since it was twice as wide as the planter and ran significantly faster, using it was a perfect task for a boy after school, rolling in what had been planted that day.
I've never seen one since I left the farm in the mid-60's and have no idea who made them. I don' think was a major brand, maybe locally produced.
