摘要

A harvester head for a harvester, with at least one advancing roller (14) which is designed for conveying a stem (20) and which has a circumferential surface (22) and a plurality of projections (24) projecting beyond the circumferential surface (22), and a rotation axis and with a diameter-measuring device for measuring a diameter (d) of the stem (20), wherein the diameter-measuring device has a probing body (28) which is moveable beyond the circumferential surface (22) and by means of which a distance between a surface (36) of the stem (20) and the rotation axis can be determined.
