Combine Harvester
The machine that reaps, threshes, and winnows grain in one pass/Cars & Road Vehicles
A combine harvester performs three harvest operations in a single machine: reaping (cutting), threshing (separating grain from stalks), and winnowing (removing chaff). Modern combines have GPS-guided auto-steer and yield mapping sensors. A large model can harvest about 100 tonnes of wheat per hour.
