Abstract
An earth-working implement and a method utilizing such an implement for preparing soil for planting seeds and concurrently planting the seeds wherein a plate-like plow stock penetrates the soil to a substantial depth below ground level, and the soil is concurrently leveled and smoothed inwardly behind the plow stock by concave and forwardly diverging cutting discs straddling the forward path of the plow stock and whose lower extremities are spaced a substantial distance above that of the plow stock for forming a substantially smooth linear area of loose soil. A furrow opener, behind the plow stock, forms a planting furrow in the soil along the linear area, while seeds are being deposited in the furrow and soil is pressed to cover the thus planted seeds. An improved mounting post arrangement is provided for supporting each of the diverging discs in predetermined angular relationship.
