A seed meter includes a seed disc rotatable in a direction of rotation. The seed disc has a plurality of seed apertures defining a circular path as the seed disc rotates and on which seeds from a seed source are entrained. A singulator is disposed along to the circular path. The singulator has a plurality of outer lobes and a first orientation lobe located downstream of the outer lobes. As the entrained seeds rotate along the circular path, the first orientation lobe contacts the entrained seeds to change their orientation. In some embodiments, the first orientation lobe may be disposed to remove excess seeds from the apertures and a second orientation lobe may change the orientation of the entrained seed.

An adjustable row cleaner includes a row cleaner assembly that functions to clear material from the ground surface. The adjustable row cleaner includes, in one embodiment, a connector that is in mechanical communication with both a row cleaner frame, to which row cleaner wheels may be pivotally mounted, and a first end of a translator member. The translator member may pivot with respect to the row unit frame and/or row unit sub-frame about a translator member pivot. The position of a translator member second end may be manipulated, thereby adjusting the maximum depth to which the row cleaner wheels penetrate the ground surface. The adjustable row cleaner may be powered or manually adjusted, and the position of the row cleaner wheels may be monitored and automatically adjusted via a control system.

A downforce controller for an agricultural implement having a double-acting hydraulic cylinder. The cylinder is configured to be coupled to an agricultural row unit and an agricultural toolbar for transmitting a net downforce between the agricultural toolbar and the agricultural row unit. A first pressure in a first chamber of the cylinder and a second pressure in a second chamber of the cylinder have counteracting effects on the net downforce. A manifold coupled to the cylinder is in fluid communication with the first chamber. A pressure control valve coupled to the manifold is in fluid communication with the manifold and the first chamber.

An apparatus for planting rhizomes includes a chassis having wheels to move in a primary direction over an area in which rhizomes are to be planted, the primary direction defining a forward and aft sense, a hopper on the chassis holds rhizomes to be planted, the hopper having a live bottom mounted to move rhizomes in the forward direction, a kickback bar at a forward side of the hopper lifts rhizomes at a forward face of the hopper, a leveling roller above the live bottom levels the height of rhizomes transported by the live bottom forward of the hopper, a barrel feed at a forward end of the live bottom to pull rhizomes from the live bottom, a accumulator below the barrel feed, a drop zone below the accumulator, and a chute with inner flaps from the drop zone oriented to deposit rhizomes in a furrow.

Agricultural seed planting systems are provided. In some aspects, the system includes a processing unit, a frame, a furrow opener coupled to the frame for opening a furrow in soil, and a sensor in communication with the processing unit and adapted to sense a characteristic associated with seed planting. The sensor may generate a signal associated with the sensed characteristic and the processing unit may receive the signal. In some aspects, the sensed characteristic may be either a soil characteristic or a seed characteristic. Information associated with the sensed characteristic can be saved in memory for future use and to assist with more effective planting in the future.

Openers for a seeder, configured to be adjustably engaged with a soil surface when in use; each opener having compliance to vertical and lateral excessive forces independently applied to soil-engaging parts: a fertiliser tine, a seed tine, a press wheel, a coulter, and a support wheel. The openers share a hydraulic circuit, linked to each internal frame-lifting ram so that localised rise and fall effects arising from soil surface irregularities are shared, maintaining a mean height. The seed tine of each opener is made liftable immediately the preceding fertiliser tine is displaced. The openers do not require external weight support.

Agricultural devices, row unit adjustment systems, and methods of adjusting a depth of a furrow are provided. In some aspects, an agricultural device is adapted to plant seeds and includes a frame, a furrow opener coupled to the frame and adapted to cut a furrow including a depth, a sensor adapted to sense a characteristic associated with planting seeds and generate a signal associated with the sensed characteristic, and a processing unit receiving the signal associated with the sensed characteristic. The depth of the furrow is adjustable based on the signal associated with the sensed characteristic. Such characteristic may be a characteristic of the soil, a force applied to the agricultural device, or a position of a portion of the agricultural device.

A supporting device for supporting a furrow device and/or for connecting the same to a seed tube of a seed planting unit is described. The supporting device may include a connection element and an alignment element joined to the connection element. The connection element may include a connection feature and a stand feature. The connection feature may be configured to attach the furrow device to the supporting device. The stand feature may be configured to position the furrow device at a desired angle relative to the furrow. The alignment element may include an alignment feature and a positioning feature. The alignment feature may be configured to axially align a longitudinal axis of the supporting device with a longitudinal axis of the seed tube. The positioning feature may be configured to position the furrow device at a desired location along a longitudinal dimension of the seed tube.
