Grain Cart Scale
The Libra Cart hardware connects to your grain cart’s load cells and uses Bluetooth® to wirelessly send data to the Libra Harvest app on your smartphone or tablet; eliminating the need for a traditional grain cart scale indicator in the cab. It automatically detects and records every unload; no PTO or additional sensors required. You get accurate, real-time harvest data without pressing any buttons, printing tickets, or writing anything down.
