    摘要： 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.

    摘要： 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.

    摘要： 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.

    摘要： A soil apparatus (e.g., a knife) to engage in soil is described herein. In one embodiment, the soil apparatus includes a soil engaging portion to engage with soil and a plurality of sensors disposed in the soil apparatus. Each sensor is independently pivotable to independently position for sensing soil characteristics of soil.
