This course, developed by the Nanjing Institute of Agricultural Mechanization—an institution under China’s Ministry of Agriculture and Rural Affairs— is designed to help farmers reduce losses and improve efficiency during mechanical wheat harvesting. It introduces key principles of identifying the optimal harvest period, recognizing crop maturity indicators, and understanding moisture‑based harvesting decisions. The course explains essential pre‑operation procedures, including full inspection, maintenance, and trial harvesting to fine‑tune machine settings such as snapping plates, husking rolls, threshing cylinders, and cleaning systems. It further provides practical strategies for reducing harvest loss through proper route planning, operating speed control, swath width adjustment, and maintaining appropriate stubble height. Special operating techniques for lodged wheat, dense or high‑moisture crops, uneven terrain, and blockage handling are also covered. By combining standardized procedures with adaptive field‑based adjustments, the course equips machinery operators with the skills needed to ensure safe, efficient, and low‑loss wheat harvesting. Ultimately, it emphasizes that mastering these techniques requires both learning and extensive hands‑on practice.
