ABSTRACT:
A packer is mounted on a tool shank of an agricultural cultivator. It includes a guide tube slideably and rotatably mounted on a rigid seed tube mounted directly on the shank. The guide tube is biased downwardly by a compression spring surrounding the seed tube. Provision is made for adjusting the position of the packer wheel to accommodate different seeding depths and packer pressures.
