    Abstract: A row unit (10) of an agricultural planter with an apparatus for adjusting the depth of a trench opened by the row unit (10). The row unit (10) includes a trench depth adjustment assembly (90T) configured to modify the trench depth. The trench depth adjustment assembly (90T) includes a depth adjustment body (5044) pivotally connected via a pivot to a frame member (14) of the row unit (10). An electric motor (5030) is operable to cause rotation of a shaft (5038) operably coupled with the depth adjustment body (5044), whereby rotation of the shaft (5038) causes the depth adjustment body (5044) to pivotally move about the pivot (92) thereby changing a position of contact of the depth adjustment body (5044) with a gauge wheel arm (54), thus changing the amount of upward ravel of the gauge wheel (52) with respect to a trench opening disc (62) and thus the depth of the trench.

    Abstract: System for adjusting the depth of a trench opened by a row unit (10) of an agricultural planter. The row unit (10) includes a trench depth adjustment assembly (90R) configured to modify the trench depth. The trench depth adjustment assembly (90R) includes a depth adjustment body (3044) pivotally connected via a pivot (92) to a frame member (14) of the row unit (10). An electric motor (3030) is operable to cause rotation of a shaft (3034) operably coupled with the depth adjustment body (3044), whereby rotation of the shaft (3034) causes the depth adjustment body (3044) to pivotally move about the pivot (92) thereby changing a position of contact of the depth adjustment body (3044) with a gauge wheel arm (54), thus changing the amount of upward travel of the gauge wheel (50) with respect to a trench opening disc (62) and thus the depth of the trench.

    Abstract: A dynamic supplemental downforce control system for a planter row unit. The system includes closed-loop feedback circuit that cooperates with a downforce actuator to dynamically control fluid flow to the downforce actuator to maintain balance between the actual gauge wheel downforce and a desired gauge wheel downforce during planting operations.

    Abstract: A method of depositing oriented seeds into a trench including forming a trench (299); depositing a foam (289) into the trench (299); and depositing seed (279) from a seed orientation device (270) into the foam (289) in the trench (299). Also, an agricultural row unit (200) having: a frame (204); an opening unit (260) connected to the frame (204) for opening a trench (299) as the row unit (200) moves in a direction of travel: a foam delivery tube (281) for delivering foam (289) into the trench (299) opened by the opening unit (260); and a seed orientation device (270) disposed rearward from the foam delivery tube (281) for delivering oriented seeds (279) in the foam (289) delivered by the foam delivery tube (281).

    IPC: A01C5/06

    Abstract: A method of planting with a row unit (100, 200) includes forming a seed trench (128) in soil with the row unit (200), dispensing a seed from an outlet of a seed-delivery mechanism (202) carried by the row unit (100, 200), penetrating a wall of the seed trench (128) with a covering device (206, 302) to cover the seed with soil, and closing the seed trench (128) with a seed-trench closing assembly (118). A row unit (100, 200) for planting seeds includes a frame (102) configured to be coupled to a toolbar (104), a seed-trench opening assembly (116) carried by the frame (102) and configured to form a seed trench (128), a seed-delivery mechanism (112, 202) carried by the frame (102) and configured to deliver seeds to the seed trench (128), a covering device (206, 302) carried by the frame (102) and configured to penetrate a wall of the seed trench (128) and cover the seeds with soil, and a seed-trench closing assembly (118) carried by the frame and configured to close the seed trench.
