[Daily Photo] Port Huron Steam Engine / 農用蒸汽引擎

I went to Greenfield Village next to the Henry Ford Museum (in Dearborn, Michigan) last week. They collect and preserve many old-time agricultural equipment in the village just like this one -- the Port Huron Steam Engine, a steam-power tractor made by the Port Huron Engine & Thresher Company. It can generate from 19 - 65 horsepower. Farmers used it to power their machine or pull/push farm equipment.

在汽油引擎尚未普及前，美國農夫使用這種蒸氣引擎來拖曳或驅動大型農具。此照片拍攝於密西根州亨利福特集團所屬的Greenfield Village。



I found the following footage on YouTube from Captkordite showing how this engine works.
下面這段影片可看到此引擎實際運作的樣子。
