Apparatus and associated methods for a coulter disk system relate to a lateral actuator module having a programmably positionable control member that is coupled to a gang of coulter disks and is operable to position a control point of the coulter disks at a predetermined position between two opposing, laterally-spaced end-of-travel positions. In an exemplary embodiment, a gang may be mechanically connected to and laterally positioned by the control point. The predetermined position may be, in some examples, dynamically calculated according to a predetermined function and based on information about conditions of the soil in contact with the coulter disks. Various embodiments may dynamically adjust the position of a gang of coulter disks to dynamically and automatically optimize the conditioning effectiveness of the gang of coulter disks in response to parametric information about the soil conditions.
