A multi-row corn header row unit allows harvesting with a single corn header having fixed distance between rows, for instance at 525 mm, and multiple distancing between rows, for which purpose it bears trimmed or emptied snouts on its sides in lieu of conventional headers. Trimmed snouts tire used in combination with lifting sets or row units designed to form an opening with greater width than that of the stripping area, allows for contact with the plant in a manner such as to avoid rubbing on the most rigid part of the stem, thus preventing shakes, breaks or excessive tilting, which certainly determines the obtention of an effective harvest, upon obtaining ears without practically any waste. That is to say, the row unit allows that plants entering from outside of the central row of the collection unit reach the same without being cut, broken, shaken or tilted.
