Typically, most farmers use what is called a grain cart to speed up the process. While Person #1 runs the combine, Person #2 runs the grain cart, virtually chasing the combine across the field, & catching the corn (or beans) from the combine's auger as the combine keeps going down the row. This requires communication between the two operators (which can be the subject of another whole post, as this is a language unique to each set of operators, and if incorrectly interpreted by husband and wife, can lead to one person sleeping on the couch that night, or grain being dropped on the ground instead of being stowed safely in the wagon & bin). My grandpa's signal for "stop" & "go faster" was the same signal.....thank god for cell phones & radios!
Hers's a great video
A grain cart is virtually a big wagon with an auger on it, so that it can be unloaded into a semi or another wagon for transport back to the bin (Person #3).
