What if I am road hunting and see them harvesting. So I stop and park my rig to the far right side of the road. I turn the engine off and shut all the doors. I walk 50 feet away from the rig. At the same time the field on one side of the road is being combined and pheasants are pouring out...
I'm with birdman and captaincoot on this one. The combine is not used to "chase" anything other than corn stalks.
As far as the farmer that has been sitting in a combine all day every day for a week or two, i don't think asking him to stop so you can walk a strip of corn is a realistic idea...
