Abstract: A combined soil agitation and aerating apparatus comprises a frame which is pulled by a tractor over untilled pasture land. A cylindrical drum is rotatably supported on the frame by a co-rotatable axial shaft. A plurality of rigid prongs are provided on the cylindrical surface of the drum which penetrate, agitate and aerate the soil as a drum is rolled over the land to be seeded. A seed dispensing unit is mounted behind and parallel to the drum and is driven by a driving connection with the shaft that rotatably supports the drum.

Abstract: An apparatus for dehulling grass seed utilizing a vibrated housing having an elongated chamber. The interior of the chamber is accessible through openings or ports that provide a plurality of entries and exits for the processing of grass seed. Grass seed is dehulled by a housing mounted pneumatic accelerator that removes the hulls from the seeds. Hulls and seeds are then directed into the interior of the chamber wherein separation of seeds from hulls and hulls containing seeds occurs. Seeds are discharged from the chamber and the hulls containing seeds are returned to the pneumatic accelerator for repeating the dehulling process.
