Crops left standing for straight combining could face high losses if growers change their mind and choose to swath after the crop has reached 80% seed colour change. If a field that ripe must be swathed, cut in very moist conditions (rain or heavy dew) to limit shattering as much as possible. The final decision on whether to swath or straight cut really needs to be made prior to the optimal swathing stage of 60% SCC.
