FURROWER IN SEEDING MACHINE

PROBLEM TO BE SOLVED: To provide the subject forruwer capable of diminishing furrowing resistance and of smoothing a furrowing operation, so designed that both left and right sides of a furrowing surface is provided with a slant leveling surface raised backwardly and externally left and right compared with a leveling surface. SOLUTION: The rear bottom of a sleigh-shaped leveling surface 1 is provided with a furrowing surface 2 having V-shaped cross-section and successively running deeper toward the rear end, and both left and right sides of the furrowing surface 2 are provided respectively with slant leveling surfaces 3 raised backwardly and externally left and right compared with the leveling surface 1. It is preferable that the slant leveling surfaces 3 on the left and right outsides each be tilted by bending upward a line outside a bending line B when compared with the bending line B ranging from the outside edge of the flat surface on the front end to the upper end of the furrowing surface 2 on the rear end.
