Antique Farm Tool?

[JKN]

I found this at an estate sale but have no idea what it is.
It has the word “Acres” on it towards the bottom.
Does anyone know what this could have been used for?

Not looking designed to crush seed.
Perhaps a seed metering device?
IF outer numbers are calibrations , a specific seed size ( by type/specie) would be likely.

It would need an inlet(gravity fed from a can on top usually , which way is up? l.o.l.) and an outlet.
Outlets could be a short pipestub a piece of hose or pipe is attached to for seed to drop through.
Other set ups exited too though.

A wild (er) guess on your piece is a chain drove the outer gear and seed fell through the slot near it.(?)

I don't know, but it looks like the two dials work together.
The first acting as a "course" adjustment (in increments of 20), and the second one "fine", (in increments of 1).

So, sure seems like it's counting or dispensing something.

That’s it!

Thanks! That is exactly what it is. I would have never figured it out.
