These are snapshots from the antique shop in Brainerd Minnesota.
This is a hayfield and that contraption must bring the hay closer to the haystack. I am not certain how it works.
Here is a closer look . The fellows in the photo seem happy.
I sent a email to a modern day cowboy who uses many old ways of harvesting, perhaps he will be able to shed some light on this old photo.
Thanks for stopping by.
Update from Orden Hartley:
It looks like a hay baler. They are feeding the hay into it and it puts out square bales.
