AutoCalibrate calibrates the BiG X yield metering system automatically by using the crop weight information from the KRONE forage wagon. Regular calibration ensures the yields are accurately measured also in varying conditions. When several harvest chains are operating in the same field only one KRONE forage wagon needs to have the weighing system and only one KRONE SmartConnect controller is required. All other trailers in the fleet can be any type of trailers of any brand.
