I  believe you are asking if you can really  'get down'  in there!    

30 inch rows,  maybe a little wider  on the  wheel track is going to be  impossible  to 'fly down'...  Fall down, sure!   getting back out,  no. 

But if you mean  if the camera  can 'see'   from up above,  if you have a flat,    then   yes!   You'd have to maneuver   around to get a good angle  looking downwards  in the wheel track.     I  got mine  when   we were about half don harvesting,  and that is the first thing I used it  to test!     Sure,    dried up corn is  pretty easy to  'see'  into,  but   I  thought  we'd be able to  even when full green.   

Keep the bird above the pipe!!!
