The seeder (1) has a variable width telescopic frame (2) including two carrier wheels (3), sower elements (4) that are divided in a regular and adjustable manner on the frame, and stoneburiers (5) associated with the sower elements. Each sower element defines a sowing row (10), which coincides with a median vertical plane of the corresponding sower element, where distance between two close sowing rows defines a spacing. Each wheel comprises twin wheels (12, 13) that are spaced relative to each other and are placed on sides of the sowing row. |
