Can someone Identify this old piece of farm machinery please

Looks to me like a part off a corn planter used to run power from the axle to the shaft that turns the, feeders in the seed bins.

What would it have gone on?
measures about 7 1/2" in diameter

Looks like the reel drive sprocket on an old wheat harvester.

A drive sprocket for use on an old field harvester. Different diameter interchangeable sprockets would be used to change speed for different tasks. Run by a chain over the notches and probably ground or wheel driven. The comment about not using for hay or grass would imply it was to be used when harvesting some type of grain while on a harvester. It is also possible it could have been used on a planter, hard to say. A manufacturer's name imprinted on the wheel might give you another clue. Definitely made for use with some type of chain driven harvester, though.

My husband agrees that it is a drive sprocket and agrees that it could be off of a number of pieces of equipment.

Yes!! It is a sprocket but not just any sprocket.
Because of its spaced out teeth means it is a slow rev's type of sprocket. Driving, as suggested, ground drive connections from axle to drive shaft, or reel drive on harvester etc. Low speeds & light loads. The chain it meshes with is a much lighter construction than the normal high power, higher revving chains like on push bikes, motor bikes & various machinery. It has economic benefits being cheaper to manufacture.
Agricultural machinery is where you'll find it. That's why it's called agricultural chain. Like the sprocket, it has ahlf as many rollers as the sprocket has teeth. Normal 'Roller chain' will run on it as long as the pitch is the same size. Pitch is distance between centres of rollers or between the teeth on sprocket. These sprockets have a tooth less leaving a double length pitch.
They come in several sizes, depending on the job at hand. For instance, the afore mentioned with fairly light loads, to the feeder conveyors on large Harvesters. That is the large housing up which the crop passes to the threshing section of the machine. The chain is a combination of 3 or 4 such chains, connected cross wise with steel bars to form an elevator arrangement. They are also used on earthmoving scrapers of the self loading elevator type scrapers.
The size/ diameter of the sprockets determine the speed of the revolutions depending on the configuration of drive & driven sprockets. They are a high wear component & are generally a throw away part.
This one being red in colour would suggest it's from an International Harvester product. Green colour is usually John Deere.
The suggestion that it is an idler sprocket is not quite right in that it is keyed & locked at the centre meaning it is a drive sprocket. Just to split hairs.
I worked for 10 years as a service manager in the Ag industry with a John Deere Dealer. A further 15 years self employed in that industry, mainly with farm machinery.
Seeing that sprocket brought a tear to my eye, having been away from it for nearly 10 years.
Hope that clears that up. Cheers ET.

It was used on a hay bailer and we use these on the ranch when I was a kid.

It is a reduction sprocket for a drag harvester. That diameter sprocket was most likely for fluffing the rows of wheat and not slow enough for bailing.
Looks like a drive sprocket on a horse drawn corn planter.
