I passed this field yesterday as they were harvesting soybeans and asked if I could climb on top of the tractor-trailer as it was being loaded. The machine that off loads to the truck, empties at an incredible rate and then heads to the combine in the field for the next load. The crew is what are referred to as custom harvesters,which are professional hired hands who earn their living helping farmers harvest their fields. This crew is Groffdale custom harvesters and they are the picture of efficiency. The owner of the farm is seen on his little John Deere tractor in the middle of the field as he oversees the operation.
