Abstract: A pollinating machine for use with plants growing in a row and having blossoms pollinated by compressing transversely of the row, the machine being mounted for movement along the row and having a pair of axially upright, cylindrical rollers spaced transversely of the row and provided individually with peripheral layers of resiliently yielding material, a pair of paddle wheels spaced transversely of the row ahead of the rollers, and mechanism rotationally driving the rollers and the wheels so that, as the machine moves along the row, the wheels gather the plants centrally of the row for compressing between the rollers.
