Full explanation
Components: (1) grain-flow sensor (impact plate or optical) at the elevator head; (2) moisture sensor (NIR or capacitive) in the grain tank; (3) GPS receiver (SBAS minimum, RTK ideal); (4) display/controller (JD GreenStar, Case AFS, Claas CEBIS, NH IntelliView, AgLeader Integra). Calibration is critical: (1) static weight load (2–3 full tanks to scales); (2) moisture calibration (sample draws + lab reference); (3) latency setting. Without calibration, errors reach ±10–15%. A properly set monitor is accurate to ±2–3%. Data uses: (1) identify low-yield zones; (2) compare hybrids/varieties (strip trials); (3) ROI analysis of treatments; (4) base layer for VRA zoning. In Ukraine yield monitors ship on all modern Western combines. Aftermarket retrofits on older Case 2166, JD 1470 (AgLeader, Farmtronics) — UAH 70k–120k [VERIFY].
