As both sprayers and precision capabilities have grown, manual machine and implement control have become increasingly difficult. To utilize this increased potential, automation becomes necessary. That’s why Topcon has developed a comprehensive suite of guidance, crop monitoring, implement control and data services technology. Acting as the glue that enables accurate and advanced application control, Norac Boom Height Control provides consistent preset height for even application and reduced drift.

Using time- and field-proven ultrasonic sensor technology, the Norac UC7 Boom Height Control solution makes responsive height adjustments, allowing booms to automatically follow the contours of the land. It helps reduce stress and fatigue while enhancing focus on machine operation and safety. Plus, providing various levels of control based on needs, the solution is designed for any operation and is compatible with a wide range of machines.
