Can anyone help to identify the brand/use of this object? From my limited research online, it seems like a very old plow wheel, but I wondered if there were more specifics (or other ideas about purpose!)

For reference, it was found on an old ranch in southeast Colorado, with some other objects which seem to date from the early 1900s. There are numbers on one edge that seem to say 18.55.34, and a super faint logo to the left of the numbers. Any idea what those might mean?

Thanks for any help!! I have very little agricultural knowledge, so anything is appreciated.

If it's thin and flat I would guess it's a disc for a plow coulter . They can break like that if they hit a large rock when plowing.

If the center hole is more square than round it's likely an old broken disc harrow blade.
They can range from 8" on older horse drawn to 22" on modern equipment.
I'm guessing the 18 on the casting would be the original outside diameter.
