Driving the combine was like piloting a ferry. These machines are enormous. They grind their way around the fields, picking up swath left to dry and crushing the seed out of the grain heads. The seed is then augured up into a box where it's stored, and when the box is full, it's augured again into a truck running parallel. Both machines work in tandem until the work is done. When the weather is threatening, crews work from dusk until dawn. Fields look like harbours as lights from the combines float across them like ships in the night.
