3 row corn picker

This 3 row corn picker caught my eye on the way to Springfield today.  Know whose farm it is sitting at, I don't think it has been used in some years.  Back in the day, Probably early-1960's, this would have been quite the machine.  It implied that the farmer probably had a 6 row planter too.  That would have been big machinery.  My dad had a 4 row planter and  2 row picker.  We did have neighbor with a 3 row corn head on the combine.  My non-farm and younger readers my not know that corn was picked on the cob and air dried in a corn crib before being shelled to be sold.  It could be ground whole for cattle feed, or fed on the cob to hogs.
