A crop sensing system for a baler (10) is disclosed. The crop sensing system comprises a compression system (28) for forming a bale (12) a feed system (26) for picking up crop (14) from a surface and conveying the crop to the compression system (28) a sensor arrangement (88) including at least one sensor (94, 98, 99, 108) being coupled to at least one of the compression system (28) or the feed system (26), the at least one sensor (94, 98, 99, 108) configured to generate a signal which corresponds to a crop load on the at least one of the compression system (28) or the feed system (26) and a control unit (112) configured to receive the signal from the sensor arrangement (88) and calculate crop mass data based on at least the signal.
