Abstract
Packer wheel assemblies attached to earthworking tools of a field cultivator compact soil about seeds dispensed into the soil with an air planter. Each packer wheel assembly has a body adjustably mounted on the shank of each tool and an arm pivotally connected to the body. Ground engaging wheels are rotatably mounted on the arm. A coil spring connected to the arm biases the wheels downwardly into engagement with the soil.

11. An apparatus for planting seed into the soil comprising:
- a field cultivator having a plurality of earth working tool assemblies for working the soil, each earth working tool assembly having a shank and a tool mounted on the shank, planter means mounted on the cultivator operable to dispense seed into the soil behind at least one of said shanks, soil packer means for compacting the soil about said seed, means mounting the soil packer means on said one of said shanks, said soil packer means having a body, said body having laterally spaced side members extended rearwardly from said one of said shanks, wheel means for compacting the soil about the seed dispensed into the soil, arm means connecting the wheel means to the body, pivot means extended between said side members and mounted thereon, said arm means extended between said side members and mounted on said pivot means for movement in generally up and down directions, means rotatably mounting the wheel means on the arm means, remote from the pivot means, stop means extended between said side members and mounted thereon generally below said pivot means, said arm means being engageable with the stop means to limit downward movement of the arm means and to maintain a selected earth working depth of the tool and depth of the seed in the soil, and biasing means for biasing the arm means in a downward direction into engagement with stop means and yieldably holding the wheel means in engagement of soil thereby compacting the soil about the seed, said biasing means comprising spring means located between said side members, said spring means having a coil portion surrounding the pivot means, first portion engageable with the arm, and a second portion engageable with the stop means whereby the coil portion of the spring biases the arm means into engagement with the stop means.
