For many researchers and growers, the HM800 has been a trusted tool for accurate plot weight and moisture data. However, as time goes on, the parts and components needed to repair or maintain the HM800 are becoming increasingly difficult to source*. This makes repairs more costly and time-consuming. That’s where the next generation of HarvestMaster™ innovation comes in—the H2/H3 GrainGage™ system. Transitioning to either an H2 or H3 GrainGage is not only a step toward better performance and data accuracy, but also the most cost-effective long-term solution for ensuring your research operations remain reliable and supported for years to come. Invest in the data, upgrade to the H2 or H3 GrainGage system and secure the future of your plot research.
Compared to the HM800, the H2/H3 GrainGage delivers increased weighing accuracy, greater measurement reliability, more efficient plot processing, and improved grain moisture analysis—all designed for today’s demanding harvest environments.
The Advantages of H2 and H3 GrainGage Systems
Both the H2 and H3 GrainGage systems are designed to deliver exceptional reliability and performance for plot harvest data collection. The H2 GrainGage offers improved slope and motion compensation for more precise weight measurements, even on uneven terrain. It features faster cycle times, larger bucket capacity, and a refined hopper design to improve grain flow and minimize bridging—helping researchers process more plots per day with less downtime.
The H3 GrainGage takes those advantages even further by integrating advanced NIR sensor and NIR (near-infrared) technology for in-field grain constituent measurement and accurate pre-calibrated grain moisture data. This powerful grain moisture testing equipment measures moisture, protein, oil, and other grain constituents instantly during harvest, eliminating the need for lab-based testing. These innovations make the H3 ideal for agricultural plot research, providing real-time data to help researchers and growers make informed decisions faster.
Both systems integrate seamlessly with Mirus software, providing a smooth workflow from data capture to analysis. With rugged components and direct compatibility with modern HarvestMaster and Juniper Systems hardware (like the Mesa Pro Rugged Tablet), the H2 and H3 GrainGage solutions ensure researchers have the most advanced and accurate tools available for every harvest season.
Upgrading to the GrainGage ensures continued technical support and access to replacement parts as older HM800 components become harder to source. This helps your harvest system stay reliable and operational for future seasons. In many cases, upgrading from an HM800 to a research harvester is simple and easy.
