Agricultural system for field preparation
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 plurality of row-cleaning devices attached in parallel strip positions along the tow bar, each row-cleaning device of the plurality of row-cleaning devices includinga rigid frame for attachment to the tow bar,a leading coulter,one or more furrow-opener disks in a trailing position relative to the leading coulter, each of the one or more furrow-opener disks having a leading edge adjacent to a trailing edge of the leading coulter, anda pivotable row-cleaning linkage attached to the rigid frame, the leading coulter and the furrow-opener disks being coupled to the rigid frame via the pivotable row-cleaning linkage; and
at least one roller device extending between two adjacent parallel strip positions and being attached at each end to a respective rigid frame via a respective pivotable roller linkage, the pivotable roller linkage being independently movable relative to the pivotable row-cleaning linkage.

Abstract
An agricultural system includes a tow bar for attachment to a towing vehicle in a trailing position relative to a direction of movement along a field. The system includes a plurality of row-cleaning devices attached in parallel strip positions along the tow bar. Each row-cleaning device has a rigid frame, a leading coulter, one or more furrow-opener disks, and a pivotable row-cleaning linkage. The disks have a leading edge adjacent to a trailing edge of the coulter. The row-cleaning linkage is attached to the rigid frame, with the coulter and disks being coupled to the rigid frame via the row-cleaning linkage. The system further includes a roller device between two adjacent parallel strip positions and attached at each end to a respective rigid frame via a respective pivotable roller linkage. The roller linkage is independently movable relative to the row-cleaning linkage.

11. 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 plurality of row-cleaning devices attached in parallel strip positions along the tow bar, the plurality of row-cleaning devices including a first row-cleaning device and a second row-cleaning device, the first row-cleaning device being attached in a first strip position and including a first rigid frame for attachment to the tow bar, a first leading coulter, one or more first furrow-opener disks in a trailing position relative to the first leading coulter, and a first pivotable row-cleaning linkage attached to the first rigid frame, the first leading coulter and the first furrow-opener disks being coupled to the first rigid frame via the first pivotable row-cleaning linkage; the second row-cleaning device being attached in a second strip position, the second strip position being adjacent and parallel to the first strip position, the second row-cleaning device including a second rigid frame for attachment to the tow bar, a second leading coulter, one or more second furrow-opener disks in a trailing position relative to the second leading coulter, and a second pivotable row-cleaning linkage attached to the second rigid frame, the second leading coulter and the second furrow-opener disks being coupled to the second rigid frame via the second pivotable row-cleaning linkage; and a roller device attached between the first row-cleaning device and the second row-cleaning device, the roller device including a first pivotable roller linkage attached at a first end of the roller device and being independently movable from the first rigid frame, a second pivotable roller linkage attached at a second end of the roller device and being independently movable from the second rigid frame, and at least one roller bearing mounted along a rotational axis of the roller device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
