Went for a short motorcycle ride today, stopped for gas and across the highway there were 3 blue-colored machines cutting soybeans. They were narrow, and had row-style heads that looked something like the pix I have seen of cotton pickers, with white snouts. As far as I know, the field is not a test plot or anything, but it was a bit out of my area. I didn't have a camera to get photos, and I didn't have the time to get up close to look or ask questions.

The beans were in rows, the machines were taking 4 rows at a time.

Can anyone tell me what I saw?
