GreenStar™ Combine Yield Systems
Consider this scenario
Your cornfield averaged 130 bushels per acre. But you suspect some areas yielded 180 bu/acre and other areas only 80. If you could verify which acres brought you higher yields (and which didn't), would you treat them differently? A combine yield-monitoring or yield-mapping system allows you to see what each farm is averaging and will allow you the capability to look into each field to see what it is actually yielding.
The components of a GreenStar™ Yield System include:
Mass Flow Sensor
The mass flow sensor is a curved impact plate located at the top of the clean grain elevator that measures true mass flow. As the grain impacts the plate, the sensor measures the slightest movement or impact. This measurement, along with the clean-grain elevator speed, is used to calculate harvested mass of the crop, calculated instantly and converted to yield. The design of the sensor provides a high degree of reliability and accuracy compared to other sensing technology. An automatic zero-update (a process similar to zero-balancing a weight wagon) eliminates the need to stop the combine multiple times each day.
To increase accuracy of the mass flow sensor, auto zeroing software is used. This system "zero's" the grain flow to discount any differences in combine circumstances. In essence, it will zero the flow at each revolution of the clean grain elevator chain.
Moisture Sensor
The moisture sensor for Harvest Doc™ and Harvest Monitor™ is located at the top of the combine's clean grain elevator inside the grain tank. It continuously samples the grain for moisture content and temperature. The system automatically converts the yield to dry bushels. Additionally, the grain moisture sensor plates are wiped clean with every cycle of the sensor's sampling routine for more accurate and consistent moisture readings in a variety of crop conditions.
