摘要： A singulating meter includes a seed disc with seed apertures rotates in a vertical plane through a seed reservoir. A horizontal seed tube has an inlet adjacent to the top of the seed disc and the seed apertures move along a seed aperture path toward the inlet. Pressurized air flows into the tube inlet, and through each seed aperture as it rotates upward out of the seed reservoir pushing a seed into each seed aperture which seed then moves along the seed aperture path through about 180 degrees of rotation to a release position at the top of the path where the seed is carried horizontally into the seed tube. An ejector pushes debris out of the seed apertures into the seed tube. An alignment guide moves the singulator element of the meter into the operating position where same is magnetically secured.

摘要： A system for a row unit of a planting implement includes a frame. A closing system is operably coupled with the frame. The closing system includes a closing arm operably coupled to the frame on a first portion of the closing arm, a closing disc operably coupled with a second portion of the closing arm, and an adjustment assembly operably coupled with the closing arm, the adjustment assembly configured to alter one or more operating parameters of the closing system. The system further includes a positioning system and a computing system communicatively coupled to the closing system and the positioning system. The computing system is configured to determine a location of the closing system based on data received from the positioning system, and alter the one or more operating parameters of the closing system from a first operating parameter to a second operating parameter based on the location of the closing system.

摘要： An agricultural row unit for use with a towing frame hitched to a tractor includes an attachment frame adapted to be rigidly connected to the towing frame, a linkage pivotably coupled to the attachment frame, and a row unit frame having a leading end pivotably coupled to the linkage to permit vertical pivoting movement of the row unit frame relative to the attachment frame. A hydraulic cylinder coupled to the attachment frame and the linkage, for urging the row unit frame downwardly toward the soil, includes a movable ram extending into the cylinder, and a hydraulic-fluid cavity within the cylinder for receiving pressurized hydraulic fluid for advancing the ram in a direction that pivots the linkage and the row unit frame downwardly toward the soil. An accumulator positioned adjacent to the hydraulic cylinder has a fluid chamber containing a diaphragm, with the portion of the chamber on one side of the diaphragm being connected to the hydraulic-fluid cavity in the hydraulic cylinder, and the portion of the chamber on the other side of the diaphragm containing a pressurized gas.

摘要： In one embodiment, one or more tangible, non-transitory, machine-readable media comprising instructions configured to cause a processor to receive a signal indicative of a residue coverage on a surface of an agricultural field from a sensor, and the sensor is positioned in front of a row unit of an agricultural product application system relative to a direction of travel. Further, the instructions are configured to cause the processor to determine the residue coverage on the surface of the agricultural field based on the signal, and the residue coverage includes a percentage of the agricultural field that is covered by residue, an evenness of the residue, or a combination thereof. Moreover, the instructions are configured to cause the processor to control an agricultural product control system of the agricultural product application system based on the residue coverage.
