During the late 19th and early 20th centuries, horse-drawn combine harvesters reached their absolute peak of scale and complexity, transforming vast agricultural landscapes like the American West and Pacific Northwest. Facing a major rural labor shortage after the California Gold Rush, manufacturers pushed mechanical boundaries to engineer giant, wooden “pull-type” behemoths that relied entirely on massive teams of animals for power.

During this period, the size of combine harvesters grew rapidly to maximize efficiency in the vast wheat fields of California, Oregon, and Washington State. To move these multi-ton wooden machines, farmers used immense teams typically ranging from 20 to 40 horses or mules. A legendary and frequently photographed standard was the 33-horse hitch, often configured in lines of up to 12 animals abreast...

Kinda makes clear why we still say horsepower
