John Froelich was an American inventor who lived in Clayton County, Iowa, and invented the first practical gasoline-powered farm tractor. John Froelich attended school at the College of Iowa. There he learned a lot about machinery. After college, he decided he would build the very first tractor. Designed by Mann and himself, Froelich was able to build a 16 horsepower (12 kW) tractor that could go both forward and backward by the year 1892.

- John Froelich was an American inventor who lived in Clayton County, Iowa, and invented the first practical gasoline-powered farm tractor. John Froelich attended school at the College of Iowa. There he learned a lot about machinery. After college, he decided he would build the very first tractor. Designed by Mann and himself, Froelich was able to build a 16 horsepower (12 kW) tractor that could go both forward and backward by the year 1892. After completing the tractor, Froelich and Mann brought it to Langford, South Dakota, where they would connect it to a J.I. Case threshing machine, and thresh 72,000 bushels of grain in 52 days. Purchased by Deere & Company in 1918, and became the John Deere Tractor Company. Froelich, who received little money or recognition for his invention, died from a heart attack in 1933, in St. Paul, Minnesota. He was inducted to the Iowa Inventors Hall of Fame in 1991.
- John Froehlich (auch Froelich) war ein deutschstämmiger, US-amerikanischer Erfinder. John war der Sohn der deutschen Auswanderer Henry Froelich und Kathryn Gutheil, die sich 1847 in Clayton County, Iowa ansiedelten. Er nahm Unterricht am College of Iowa, wo er Maschinenbau studierte. Nach Absolvenz des College nahm er sich vor, einen benzinbetriebene Traktor für die Landwirtschaft zu konstruieren. Bis dahin waren Traktoren von schweren Dampfmaschinen angetrieben worden. Gemeinsam mit Mann konnte er diese Konstruktion bis zum Jahr 1892 realisieren. Nach der Fertigstellung des 16 PS Traktors brachten die beiden Konstrukteure ihre Maschine nach Langford, South Dakota, wo sie sie an eine Dreschmaschine ankoppelten. Innerhalb von 52 Tagen konnten sie damit 72.000 Scheffel Getreide dreschen. Die Erfindung wurde 1918 von Deere & Company vermarktet. Froehlich erhielt für seine Entwicklung jedoch weder viel Geld noch größeren Ruhm. Er starb fünfzehn Jahre später an Herzversagen.
