(Just recalling my instructor getting twitchy because there was a tractor in the next field when I was doing an auto during my 206 requal many years agao.)
I recall the same scenario, doing autos to a field, only I was the twitchy one about the tractor ahead. Instructor says "It's just another obstacle, stay away from it." I think I was mainly concerned about Farmer Joe soiling his shorts when something big falls out of the sky near him.
