MIDROW LEVELLING ATTACHMENT FOR A SEEDER

摘要

24 A midrow levelling attachment for a seeder includes a set of leveller gangs each of which is mounted on a respective one of the packer wheel gangs of the seeder by a pair of mounting members one at each end of the common shaft of the leveller gang. The levelling roller gang is arranged such that each roll er has the peripheral surface thereof located at a position aligned with a location on the ground between a respective pair of the shanks of the seeder and each roller is located rearwardly of the respective pair of shanks and in front of the packer wheel s for engaging the ground between the furrows formed by the furrow forming element of the respective pair of shanks. The peripheral surface of each levelling roll er is shaped with an apex and two inclined sides such that as the peripheral surfa ce rolls over the ground between the furrows it tends to push the soil back into the furrows.
