John Deere, combine harvesters, and the machines that feed the world.
Before tractors, one farmer could feed about 4 people — today, thanks to modern agricultural machinery, a single farmer can feed over 155 people. This 50-question quiz covers the entire history of farm vehicles, from steam-powered plows through John Deere's iconic green machines, the economics of $800,000 combine harvesters, GPS-guided precision agriculture, and the autonomous tractors reshaping farming's future.
Before tractors, one farmer could feed about 4 people. Today, a single farmer feeds over 155. This quiz celebrates the machines that made that transformation possible, from steam engines to GPS-guided autonomous tractors.
Each round presents 10 randomized multiple-choice questions drawn from a pool of 50, so every playthrough is different. You get instant feedback with explanations after each answer, plus a shareable score at the end.
You'll explore tractor history from the first gasoline model in 1892 through the Fordson and Farmall revolutions, John Deere's origin story and right-to-repair controversy, combine harvester economics, GPS precision agriculture, autonomous farming technology, and the global manufacturers that keep the world fed.
John Deere tractors have been green with yellow trim since 1918. Green was a practical choice that blended with fields, and the combination became so iconic that Deere trademarked the specific shade. Today 'John Deere green' is recognized worldwide.
Modern combine harvesters typically cost between $500,000 and $800,000 or more. Top models like the Claas Lexion 8900 can exceed $800,000 fully equipped, and headers alone can add $50,000 to $150,000.
Precision agriculture uses GPS, sensors, drones, and data analytics to manage crops at a localized level. GPS auto-steer guides tractors within 1 inch accuracy, while variable-rate technology adjusts inputs based on real-time soil and crop data.
