Mature green fresh market tomatoes have been machine harvested on a commercial scale in California since 1978. The harvesting and handling process results in some damage to the fruit, and the incidence of puncture injury is a function of the percentage of fruits which retain their stems. This paper reports on a study to identify concepts for mechanically stemming the tomato fruits, concepts which, preferably, might be incorporated in the harvesting machine, so that machine productivity could be increased while maintaining or possibly reducing the size of crew required in the field. Parallel rollers were used to study fruit stem orientation and stemming of mature green fresh market tomatoes. Stemming efficiencies of more than 95% were achieved by using a padded, tri-roller assembly with a fruit constraining bracket.
