The McNallys have about 500 acres of corn and soybeans, Jeff McNally said.
"Once we get going, it won't take long," Hanuska said. "We're harvesting high-moisture corn to go into the Harvestore."
The high-moisture corn is used to feed cattle in the McNally's dairy operation, but it dries out the longer it stays in the field.
Tom McNally and his father, William McNally, had some award winning herds, according to Janesville Gazette records.
The McNallys were honored for having the top herd in 1979 by the Rock County Dairy Herd Improvement Association. Their 61 cows averaged more than 17,000 pounds of milk, which was quite an accomplishment decades ago.
They were then honored a decade later by the Tri State Breeders Cooperative for herd productivity.
The farm has been in the family for more than a century.
