A row crop harvester with a plurality of pairs of resiliently faced elevator belts traveling at about ground speed, one pair for each row of broccoli. As the harvester advances, each pair of belts converges upon and grasps in sequence the standing broccoli stems between them as a sickle mounted below the belts severs them from the growing plants. The belts in each pair travel at slightly different speeds so as to rotate each severed stem about its axis as it is carried past leaf beaters that both remove the leaves from the rotating stem and simultaneously draw each downwardly until its flower resides adjacent the traveling belts. Rotary knives then trim the depending stems to a uniform length and the elevator belts deliver the trimmed stems to a chaff separator and subsequent inspection and loading stations.
