Agricultural field preparation device

An agricultural system associated with reduced tillage techniques in a field, comprising:

• a frame for attachment to a towing vehicle movable in a direction of travel along a plurality of adjacent rows of residual plant matter, the plurality of adjacent rows including a first row that is parallel to and separated by an in-between region from a second row, and a third row that is parallel to and separated by a second in-between region from the second row;
• a plurality of crimping devices, each supported by the frame and positioned perpendicular to the direction of travel, a first of the crimping devices being configured to at least partially crush stems of the residual plant matter located in the first row, the second row, or in the in-between region, the first of the crimping devices extending across the direction of travel to cover (a) at least in part the first row, (b) at least in part the second row, and (c) the in-between region, a second of the crimping devices being configured to at least partially crush stems of the residual plant matter located in the second row, the third row, or in the second in-between region, the second of the crimping devices extending across the direction of travel to cover (a) at least in part the second row, (b) at least in part the third row, and (c) the second in-between region;
• and
• a plurality of separators, each supported by the frame in an overlapping position with a corresponding one of the crimping devices, a first of the separators being configured to form and maintain a first strip of exposed soil in the first row, the first of the separators being positioned in a center area of the first row perpendicularly to the direction of travel, and a second of the separators being configured to form and maintain a second strip of exposed soil in the second row, the second of the separators being positioned in a center area of the second row perpendicularly to the direction of travel, the first of the crimping devices being movable relative to the first of the separators, and the second of the crimping devices being movable relative to the second of the separators independently of movement of the first of the crimping devices relative to the first of the separators as the towing vehicle is moving in the direction of travel.
