A seeding machine having a main seed hopper is in communication with a planting unit by a flexible tube. The planting unit has a horizontal working position and a vertical transport position. The main hopper supplies seed by gravity to the planting unit through the flexible tube. The planting unit is provided with a vacuum seed meter. The seed meter has a seed disc with a vacuum side and a working seed puddle side. An isolator brush; arranged in a chordal manner on the seed puddle side of the seed disc, defines the discharge area of the seed meter. A first brush intersecting the isolator brush extends downwardly and radially inward along the seed disc. The first brush, together with the isolator brush, defines boundaries of a transport seed puddle when the planting unit is pivoted into its vertical transport position. A second brush extends downwardly and radially inward along the seed disc. The first and second brushes define a seed return gap through which seed from the top of the seed meter can be returned to the working seed puddle.
