Photos: Minnesota farm family's corn harvest is labor of love

Thousands of pounds of corn flow from combine to tractor trailer.
1 Thousands of pounds of corn flow out of a combine into a tractor trailer on the Collins Family Farms on Tuesday, Oct. 24, 2017. On a good day, they can harvest 26,000 bushels of corn a day — more than 1 million pounds, according to Nathan Collins.

7 Lights from the combine illuminate debris from harvesting corn as the harvest presses on into the evening. A September storm flattened many of the corn stalks in this field, causing them to pile up instead of feeding into the combine.

10 Nathan Collins gets out of the combine to clear flattened corn stalks from the combine's head. Despite the combine's technological capabilities, including GPS mapping, auto steering and Bluetooth, Nathan pays close attention to the machine. "You have to use all five senses," he said. "You can smell hot oil or hear when something gets stuck."

12 "This is my vacation," Nathan Collins said from the driver's seat of the combine, adding that working 90 hours in a week is not a big deal this time of year, and he cherishes the time out of the office.

14 Corn cobs sit on the head of a combine before being pulled in, where the machine separates the kernel from the cobs, and ejects the cob, stalk and husk behind the tractor and back on to the fields. Every acre of the farm is managed meticulously, and the brothers measure the efficiency of fertilizer, precipitation and different varieties to maximize their profits.
