Classic GrainGage
Exceptional Data Collection for Small Grains
HarvestMaster’s Classic GrainGage™ is specially designed to collect highly accurate grain trait data on cereals and small grains. By processing multiple samples from a plot, the Classic GrainGage provides reliable measurements for moisture, test weight, and plot weight, even on sample sizes as small as 900 grams. With the Classic GrainGage, you can record data on a variety of plot sizes and grain types, without the maintenance that comes with traditional buckets. Field researchers trust HarvestMaster GrainGages for accurate, efficient field data collection.

Absolute Precision
The Classic GrainGage™ utilizes HarvestMaster’s reliable HM800 electronics to attain excellent data accuracy for critical measurements like weight, moisture, and test weight, while eliminating the need for large, bulky cables. GrainGages also use patented slope and motion sensors and an Electromagnetic Grain Moisture Sensor™ to provide highly accurate measurements, even on high-moisture grains. To further increase accuracy, the Classic GrainGage processes grain in small batches, averaging the moisture and test weight from multiple measurements for the most reliable results.
Increased Efficiency
The Classic GrainGage uses specialized sensors that compensate for vibration and movement, allowing you to harvest strip trials and normal-length plots without stopping the combine, and ultimately, increasing speed and efficiency.
Mirus™ Software - Easy-To-Use, Yet Powerful
The Classic GrainGage is optimized to use with HarvestMaster’s Mirus™ software, a powerful, yet easy-to-use tool that allows researchers to collect and monitor plot harvest data as it’s collected. Learn more about Mirus here.

*Accuracy of the weighing system can be adversely affected due to excessive vibration and shock. To achieve specified weight accuracy on moving machines, the HarvestMaster patented Slope & Motion Sensor must be enabled. Dynamic forces on the system in any direction should not exceed a magnitude of 0.8 g and the slope of the weighing platform should not exceed 10 degrees.
