Deer in farm country are use to the sound of farm equipment. If you can, be in your stand while the combine is in action. Deer will bed down in standing corn. If it's a decent sized field the combine will push them towards the side of the field that is still uncut. Once the rows are too few the deer will move into the timber. I've actually seen deer standing on the edge of the field watching the combine go.

As a few others have said also, deer seem to like the freshly picked rows. It doesn't matter how good the combine is there is always going to be some corn left in the field. I guess rummaging around on the ground for it is more natural than taking it off the stalk.
