I don't really think it's gonna work.

It's only looking like it's working because the wind is blowing away from his field. I think he just ruined more wheat.

It has worked, you can see from that last shot the fire had reached it and was smoldering,Theirs a guy at the back moping it up with a truuck and water.
Its not that gutsy, it was only a grass fire he could have driven over the top of that from the cab of the tractor and been safe. It looks like its whats left over from harvest possible wheat stems/stuble

Yeah, I think it was working. Winds can get very strong in Eastern Colorado / Western Kansas; if the wind was blowing hard the other way it might make the jump but as long as it didn't shift that way I bet it was OK.

I agree with @song77 - I think it was just a wheat stubble field. In older days it was pretty standard practice to plow that stubble back into the soil, but the more modern style is to leave it standing to serve to catch snow in the winter and then let that melt and add to the soil moisture (called no-till farming). Fires that burn off stubble can result in insurance claims for damages related to lost potential water collection from that melted snow, but the assessed damages aren't usually very high.

Source: Grew up in a Western Kansas farm family, had an incident where my family was burning tumbleweeds and caused an accidental fire that burned up some stubble in a neighboring field. Our insurance had to pay some damages to the neighbor farm.

A small amber can easily fly over that fire line.

Embers would fly in the direction of prevailing winds wouldn't they? They're doing what they can do with what they've got to work with here-
