A bagger for fruit or other discrete articles ensures that the bag has a minimum weight of fruit but with the lowest overage practical. A weigh pan is fed by a first conveyor having a number of singulating lanes, with an individual weigh chute at the end of each lane. The conveyor is controlled to stop filling the pan once a certain number of articles (sensed by photosensors) have passed into the pan which is less than the expected number of articles which will meet the minimum weight of articles to be bagged. Then the individual weigh chutes are loaded with one article each, and the individual or combinations of weights of one or more articles from the weigh chutes are calculated. The desired individual combination is selected which causes the weight of articles in the pan to exceed the predetermined weight by the lowest amount, and that desired individual or combination of articles is fed to the pan, the weight is confirmed in the pan, then the pan tilted to discharge the articles. A second conveyor feeds the first conveyor, and a shunt is provided to divert all, none, or some articles from the second conveyor to the first conveyor.
