I agree.  All my baling is done with 4x4 big bales but will be switching over to 3x4s in the near future.  but i would think that something like this could be used for small squares, round bales also. there would be a market for it i would think. We already have monitors that control all the functions of the baler and gps in the tractors so wouldnt think it would be that big of a issue for some one to come up with something.
