ABSTRACT:
A seeding apparatus is provided which includes a V-shaped frame having forward and rear arms of which the forward arm is hitchable to a tractor or other vehicle for pulling such apparatus. The seeding apparatus includes a carriage assembly which supports a furrow opener at one end of the carriage assembly adjacent the V-shaped frame. The seeding apparatus further includes a furrow closer at the remaining end of the carriage assembly. The carriage assembly is coupled to the rear arm of the frame by a spring mechanism which downwardly biases the furrow opener and closer toward the soil when the furrow opener and closer are in contact with the same. A second dual spring mechanism is situated between the hitch and the forward arm of the frame to further bias the furrow opener and closer downwardly when the furrow opener and closer contact the soil.
