Using a flop-over horse-powered hay rake, a Kelley Farm guide windrows yesterday's cutting. Raking hay is an important step in the process of getting hay to dry and cure in the sun and wind. Clover and Timothy grass hay were popular 19th-century forage. Oliver Kelley was the first Minnesota farmer to import Red Clover seed to grow for hay.

Riding atop a load of hay, a Kelley Farm guide heads to the barn with another load of hay. In a good year, the Kelley Farm can produce much of its own animal feed. Drought and temperature extremes hurt farm production today just as they did in the 19th-century.
