Greentronics is a technology business founded in 1994. Our vision states: "Greentronics is a recognized name for specialized products in international markets that make farming more efficient.” The company started as a partnership between brothers Bert and Bill Menkveld who have a family history in farming. Greentronics focuses on providing solutions for specific needs on agricultural equipment. Over the years, we developed an Automatic Levelling Controller, a Sonar-Sensor-based Automatic Height Controller for potato harvester booms, sprayer booms and for planting depth control. Greentronics is also well known for its load-cell based root crop Yield Monitors, In-Line Conveyor Scales and fertilizer Rate Monitors.
