Combine Harvester Yield Mapping System

Continuous grain yield measurement with real-time georeferencing

IoT GPS/GLONASS Load Cells AgriTech

Challenge

Very few combines in Russia are equipped with yield mapping systems. Without accurate field-level yield data, it is impossible to optimize fertilizer application, identify problem zones, and improve overall farm efficiency.

  • No accurate yield data by field zones
  • Cannot optimize variable rate fertilizer application
  • Foreign turnkey systems do not fit domestic combines
  • Agronomists work with averaged data, losing up to one-third of potential

Solution

Embedded system for RSM (ACROS/Rostselmash) combines. A load cell or impact plate on the grain elevator measures mass flow. A GPS/GLONASS module georeferentces the data. The computing unit generates a real-time yield map.

  • Grain mass flow sensor on elevator (load cell or impact plate)
  • GPS/GLONASS module with real-time georeferencing
  • Grain moisture sensor for yield normalization
  • Computing unit and operator display in cab
  • Map export to ISOXML, GeoJSON, CSV for АгроСигнал and ESRI

Key Advantages

🗺️

Yield maps

Visual field zone maps — foundation for precision farming and agrochemical optimization.

🌾

For domestic combines

Designed for RSM production combines without modifying standard systems.

📤

АгроСигнал export

Yield data integrates directly into the farm management platform.

💧

Moisture compensation

Yield normalization by moisture content for cross-season comparison.

Technologies

  • Load cell / impact plate on elevator
  • u-blox GPS/GLONASS module (RTK optional)
  • NIR grain moisture sensor
  • Computing unit (embedded Linux)
  • 10" operator display
  • ISOXML / GeoJSON / CSV export
