ABSTRACT:
A dual packer unit is disclosed that is particularly useful for sod seeding purposes. The apparatus includes an H-shaped mounting bracket consisting of an arcuate leg connected at opposite ends to a pivot arm and a wheel mounting arm. The pivot arm is integrally formed with one end of the arcuate leg at the central portion of the pivot arm, and the wheel mounting arm is integrally formed with the other end of the arcuate leg at the central portion of the wheel mounting arm so that the ends of the pivot arm may be pivotally mounted between a pair of seed tubes, and packer wheels may be mounted for free rotation at the ends of the wheel mounting arms. When so mounted, each packer wheel is received in a furrow immediately following and in line with the seed tube. The packer wheels are gravity biased downwardly toward a cut furrow, and the unit therefore provides sufficient flexibility to follow the contour of the ground and to follow the cut furrow regardless of the depth selected.
