Abstract

An agricultural system includes a tow bar, a first row-cleaning device, and a second row-cleaning device. The first row-cleaning device is attached to the tow bar via a first frame and includes a first roller device in a trailing position relative to a first furrow-opener disk and configured to crush standing residual plant matter along a first path on a field. The second row-cleaning device is attached to the tow bar via a second frame and includes a second roller device in a trailing position relative to a second furrow-opener disk and configured to crush standing residual plant matter along a second path on the field. The second roller device is offset longitudinally from the first roller device.

First claim

1 . An agricultural system comprising:
a tow bar for attachment to a towing vehicle in a trailing position relative to a direction of movement along a field; a first row-cleaning device attached via a first frame to the tow bar, the first row-cleaning device including at least one first furrow-opener disk and a first roller device, the first roller device being in a trailing position relative to the at least one first furrow-opener disk and having a first longitudinal axis perpendicular to a direction of movement V along the field, the first roller device being configured to crush standing residual plant matter along a first path on the field; and a second row-cleaning device attached via a second frame to the tow bar, the second row-cleaning device including at least one second furrow-opener disk and a second roller device, the second roller device being in a trailing position relative to the at least one second furrow-opener disk and having a second longitudinal axis perpendicular to the direction of movement V along the field, the second longitudinal axis of the second roller device being offset from the first longitudinal axis of the first roller device, the second roller device being configured to crush standing residual plant matter along a second path on the field.

2 . The agricultural system of claim 1 , wherein the first longitudinal axis of the first roller device is at a first distance D 1 from the tow bar and the second longitudinal axis of the second roller device is at a second distance D 2 from the tow bar, the second distance D 2 being greater than the first distance D 1 .

3 . The agricultural system of claim 1 , wherein adjacent ends of the first roller device and the second roller device overlap a distance X 1 .

4 . The agricultural system of claim 1 , wherein at least one of the first furrow-opener disk and the second furrow-opener disk is a forged blade with an induction hardened edge.

5 . The agricultural system of claim 1 , further comprising a third row-cleaning device attached via a third frame to the tow bar, the third row-cleaning device including at least one third furrow-opener disk and a third roller device, the third roller device being in a trailing position relative to the at least one third furrow-opener disk and having a third longitudinal axis perpendicular to the direction of movement V along the field, the second row-cleaning device being positioned longitudinally between the first row-cleaning device and the third row-cleaning device, the third roller device being configured to crush standing residual plant matter along a third path on the field.

6 . The agricultural system of claim 5 , wherein the third longitudinal axis of the third roller device is aligned with the first longitudinal axis of the first roller device.

7 . The agricultural system of claim 5 , wherein first longitudinal axis of the first roller device is at a first distance D 1 from the tow bar and the second longitudinal axis of the second roller device is at a second distance D 2 from the tow bar, the second distance D 2 being greater than the first distance D 1 , the third longitudinal axis of the third roller device being at a different distance from the tow bar than either distance D 1 or distance D 2 .

8 . The agricultural system of claim 5 , wherein adjacent ends of the second roller device and the third roller device overlap a distance X 2 .

9 . The agricultural system of claim 1 , further comprising a fertilizer injector mounted to at least one of the first row-cleaning device or the second row-cleaning device, the fertilizer injector trailing in part the respective one of the first roller device or the second roller device and being configured to deposit a fertilizer into a furrow formed by a respective one of the at least one first furrow-opener disk or the at least one second furrow-opener disk.

10 . The agricultural system of claim 9 , further comprising a fertilizer opener disk mounted to at least one of the first row-cleaning device or the second row-cleaning device, the fertilizer opener disk being in a trailing position relative to the respective one of the first roller device or the second roller device, the fertilizer opener disk being in a leading position relative to the fertilizer injector, the fertilizer opener disk being configured to prepare the furrow for receiving the fertilizer.

11 . An agricultural system comprising:
a first row-cleaning unit having
a first frame configured for mounting to a tow bar,
at least one first furrow-opener disk attached to the first frame in a leading position and being configured to form a first furrow,
a first roller device attached to the first frame in a trailing position relative to the at least one first furrow-opener disk and being configured to crush standing residual plant matter along a first path in a field, the first roller device having a first longitudinal axis perpendicular to a direction of movement V along the field, and
a fertilizer injector attached to the first frame in a trailing position relative to the first roller device and being configured to deposit fertilizer into the first furrow; and
a second row-cleaning unit having
a second frame configured for mounting to a tow bar,
at least one second furrow-opener disk attached to the second frame in a leading position and being configured to form a second furrow,
a second roller device attached to the second frame in a trailing position relative to the at least one second furrow-opener disk and being configured to crush standing residual plant matter along a second path in a field, the second roller device having a second longitudinal axis perpendicular to a direction of movement V along the field, the second longitudinal axis of the first roller device being offset from the first longitudinal axis of the first roller device, and
a fertilizer injector attached to the second frame in a trailing position relative to the second roller device and being configured to deposit fertilizer into the second furrow.

12 . The agricultural system of claim 11 , wherein the first longitudinal axis of the first roller device is at a first distance D 1 from a position of the tow bar and the second longitudinal axis of the second roller device is at a second distance D 2 from a position of the tow bar, the second distance D 2 being greater than the first distance D 1 .

13 . The agricultural system of claim 11 , wherein adjacent ends of the first roller device and the second roller device overlap a distance X 1 .

14 . The agricultural system of claim 11 , wherein at least one of the first furrow-opener disk and the second furrow-opener disk is a forged blade with an induction hardened edge.

15 . The agricultural system of claim 11 , further comprising a fertilizer opener disk mounted to at least one of the first row-cleaning unit or the second row-cleaning unit, the fertilizer opener disk being in a trailing position relative to the respective one of the first roller device or the second roller device, the fertilizer opener disk being in a leading position relative to the fertilizer injector, the fertilizer opener disk being configured to prepare the furrow for receiving the fertilizer.

16 . The agricultural system of claim 11 , further comprising a fertilizer opener disk mounted to at least one of the first row-cleaning unit or the second row-cleaning unit, the fertilizer opener disk being aligned with the respective one of the first roller device or the second roller device.
