I stood helpless by the fence while our wealthy neighbor laughed at my 17-year-old daughter for hitching two old mules to a rusted 1947 corn picker.

Gene stood at the stall door for a long time. He looked at August, our tired twenty-one-year-old mule, resting in the hay. He looked at my seventeen-year-old daughter, Greta, sitting quietly with a book in her lap. And he kept looking at the heavy leather harness hanging on the wall, oiled, supple, and perfectly maintained.

The arrogance that had fueled his laughter at the fence line was entirely gone.

“Your grandfather was a good man,” Gene said quietly.

“I know,” Greta replied.

Gene swallowed hard. “I told people keeping those mules was a fantasy.”

Greta looked at him with the incredible steadiness of someone who had just been tested by the world and won. She didn’t raise her voice. She didn’t demand an apology for the humiliation at the fence line.

“My grandfather used to say a machine that runs on fuel you have to buy is a machine someone else controls,” Greta said.

Gene nodded slowly, staring at the leather traces. “He was right.”

“He was right about a lot of things,” Greta told him. “People just stopped listening.”

Gene was quiet. The rain was still hammering against the tin roof of the barn, washing away the memory of the crisis we had just survived. The wealthiest farmer in Tama County shifted his weight, humbled by a teenage girl.

Then he asked, “What would it take to learn?”

Greta tilted her head. “To work mules?”

“Not to replace my combine,” Gene said quickly. “I’m not giving up my 9600. But to understand it. To have something like it as…” He searched for the right word.

“A backup,” Greta provided.

Gene nodded. “A backup.”

Greta studied him for a moment. Then she said, “Come back Saturday. I’ll show you what Grandpa showed me.”

Gene Crowley came back that Saturday. And the Saturday after that. The man who had mocked the past as useless admitted he was not a natural student of draft animals. But Greta was patient with him, the same way my father Einar had been patient with her. She taught the wealthiest farmer in the county how to fit a collar, how to read a mule’s mood from the tension in its neck, and how to never lie to an animal with a long memory.

The following spring, Greta graduated high school and went to Iowa State to study agriculture. She spent two years filling notebooks with research on draft animal systems, diversified farming, low-input economics, and resilience. Then, she came home. Not because she failed, but because our farm was where the real questions lived.

I didn’t just let her come back. I asked her to.

By 1998, our farm looked completely different. We still had a modern combine, because Greta wasn’t romantic about inefficiency. But we also had a working draft program integrated into the farm. Mules handled the light hauling and field tasks where a 200-horsepower tractor was unnecessary. Purchased fuel use dropped by forty percent. Redundancy had replaced dependence. Gene Crowley, taking her lessons to heart, had purchased two Belgian mares of his own.

In 1999, Greta was invited to speak at the Farm Bureau meeting. She was twenty-three years old. Sixty farmers sat in the room, most of them older men, many of them the exact same men who had parked by the fence in 1993 and laughed at her.

Greta walked up to the podium carrying her notebooks, her numbers, and Einar’s leather harness. She hung the harness on a hook near the podium, letting it sit there in plain view.

She didn’t lecture them. She didn’t tell them mules were better than tractors. Instead, she showed them the field-by-field numbers. She showed the fuel costs, the soil compaction differences, and the backup capacity. She explained that harvesting those 130 acres wasn’t a miracle; it was the result of maintaining an alternative when everyone else had mistaken single-system efficiency for strength.

“My grandfather built a farm that could keep running when the things you buy stopped coming,” she told the silent room. “We decided that was old-fashioned. We decided efficiency meant one system, one fuel source, one supplier, one account.”

She looked to the back of the room, right at me.

“When that one thing failed, we had nothing. The lesson is not that mules are better than tractors. The lesson is that any farm dependent entirely on things it cannot control is always one phone call away from standing in a parking lot wondering what to do next.”

For a long moment, nobody clapped. It wasn’t out of disrespect. It was because sixty men were thinking all at once.

Then, Gene Crowley stood up.

He was sixty-four by then. He started clapping. The rest of the room rose with him, a massive standing ovation for the girl they had once written off. I stood last, rising slowly, clapping without taking my eyes off my daughter.

Twelve years later, in 2011, Greta’s own nine-year-old daughter, Sophie, came to the kitchen table with a notebook of her own. She told Greta she had been reading about cover crops and soil biology.

Greta didn’t laugh. She didn’t say, That’s not how this works anymore. She did exactly what Einar had done for her, and what I had finally learned to do. She listened. They started with twenty acres, and eventually, it became the whole farm.

Today, our farm still sits on a county road that carries plenty of traffic during harvest season. There is a modern combine in the machine shed. There are Belgian mules in the paddock behind it.

And the 1947 New Idea horse-drawn picker still sits under a canvas tarp. Greased. Maintained. Ready.
