ABSTRACT:
An apparatus and method for tilling a seedbed with a soil manipulation device comprising a tilling shank for forming a groove in the soil followed a pair of coulter blades for closing the groove and a rear finishing device such as a rolling basket for further tilling and firming of the soil with improved coulter downward pressure and shank head. Downward pressure on the coulter blades is provided by a coulter spring attached to a lever arm pivotally attached to the framework which applies downward pressure to the framework supporting the coulter blades. The rear finishing device is connected to the same coulter support framework by a pivotal rear arm and a rear arm spring such that when the rear finishing device is displaced upward by changing field conditions, an upward force is imparted to the coulter support framework thus raising the coulter blades in response to changing field conditions. Further, a shank head is disclosed which has narrow leading center point flanked on either side by secondary points placed behind the behind the center point and which breaks up soil hardpan with a minimum of soil disturbance at the surface.
