Hobart I. Nutter – The Self-Propelled Harvester

Episode Summary:

Before tractors ruled the fields and machines moved on their own, one Ohio farmer imagined a better way to harvest. In this episode, we explore how Hobart I. Nutter turned sweat and soil into a mechanical revolution—by inventing the first commercially successful self-propelled combine harvester.

This is the story of how one man’s rural problem became a national solution—and changed farming forever.
