The invention relates to a distribution device (10) for granular material, in particular seed, having: a distributor housing (24) which has a material inlet opening (16) for the granular material; at least one conveying air duct (26a, 26b), situated in the distributor housing (24), for a material-free conveying air flow, the conveying air duct (26a, 26b) being connected within the distributor housing (24) to a grain-holding region (30, 30a, 30b) within which the granular material entering the distributor housing (24) via the material inlet opening (16) can be introduced into the material-free conveying air flow; one or more material flow lines (18a, 18b, 32, 32a, 32b), which adjoin the grain-holding region (30, 30a, 30b), for the conveying air flow laden with granular material; and at least one additional air duct (34), which is situated in the distributor housing (24), for a material-free additional air flow, which can be introduced into the one or more material flow lines (18a, 18b, 32, 32a, 32b) via at least one additional air inlet (38a, 38b).

A row unit for a seeding implement features a coulter disc, an angularly variable link on which the disc is carried, a scraper body supported on the link, and a wing projecting laterally from an outer side of the scraper body. The scraper body is supported in an adjustable manner selectively repositionable into a plurality of differently pitched orientations, relative to the link, about a reference axis that transversely penetrates the disc plane. By adjusting the pitch angle of the scraper body in a local reference frame of the link, one can better achieve a proper effective working orientation of the wing for each of a plurality of differently angulated link positions, each of which corresponds to a different working depth of the row unit. Though this novel adjustability, winged scrapers previously limited to use on parallel link row units can now be effectively used on other row units.

In one aspect, an agricultural planted is associated with an apparatus, a system and/or a method for calibrating a depth control arrangement in each of one or more row units adapted for attachment to a toolbar of the planter, where each row unit has a depth controlling linkage arrangement operatively connected to an adjustable-depth gauge wheel of the row unit. The linkage arrangement includes a load-sensing element that is monitored during adjustment of a calibration mechanism of the linkage arrangement to remove tolerance stack-up in the linkage arrangement and achieve a uniform desired value of the present load on the linkage arrangement of each of the one or more row units that is consistent with a zero-depth or other reference depth setting.

An agricultural row unit having a coulter assembly comprising a pair of gauge wheels and a coulter between the pair of gauge wheels, wherein the coulter is configured to penetrate soil and cut debris. The row unit also having a soil engaging assembly comprising sweep and a seed tube, wherein the sweep is configured to open a seed channel and the seed tube is configured to deposit seeds into the seed channel. The row unit also including a closing assembly configured to replace soil displaced by the coulter and sweep. The row unit configured for independent and optionally automatic variable depth control of the seed channel.

A depth gauge wheel for a row planter. The depth gauge wheel sets the planting depth for the seeds planted by the row planter. The depth gauge wheel sets planting depth by setting the cutting depth of the disk opener of the row planter. The depth gauge wheel also scrapes mud from the disk blade of the disk opener. The depth gauge wheel includes a rim, a tire attached to the rim and a ring attached to the rim. The tire contacts the surface of the ground to set the cutting depth of the disk opener and the ring scrapes mud from the disk blade of the disk opener.

A row unit for a work vehicle includes a row unit frame with a closer frame. The closer frame defines a longitudinal axis and a transverse axis. The closer frame is supported for rotational movement about a substantially vertical steering axis to vary a turning angle between the longitudinal axis the vehicle longitudinal axis. The row unit includes a closer implement assembly with first and second closer implements and a walking beam construction. The first and second closer implements are attached to opposite areas of the walking beam construction. The walking beam construction is rotationally attached to the closer frame to support rotation of the closer implement assembly about the transverse axis. The first and second closer implements are configured to move ground material into a ground opening from opposites sides as the work vehicle moves across the field.

A harvesting and sowing integrated compound operation machine, including a combine harvester, a stubble cleaning device, a topsoil loosening device, a fertilization device, a rotary tillage and ditching device, a sowing device, a detection device, a first driving device, a second driving device and a control device, wherein the stubble cleaning device is mounted below a header of the combine harvester; and the topsoil loosening device, the fertilization device, the rotary tillage and ditching device and the sowing device are mounted at a rear of a chassis of the combine harvester.

The disclosed apparatus, systems and methods relate to devices, systems and methods for on-the-go monitoring and controlled feedback in a supplemental downforce application. Certain implementations provide real-time monitoring of furrow depth via contact and non-contact approaches, some of which are combined with gauge wheel feedback to calibrate and otherwise control the application of supplemental downforce to the row unit. A combination of sensor types are employed in collecting furrow depth measurements, which can be used to adjust the supplemental downforce through a control system module. A gauge wheel load sensor may be used to modify the application of supplemental downforce.

In one aspect, a system for controlling the operation of a residue removal device of a seed-planting implement may include a residue removal device configured to remove residue from a path of the seed-planting implement. The system may also include a sensor configured to capture data indicative of a residue characteristic associated with a portion of the field within a detection zone positioned forward of the residue removal device relative to a direction of travel of the seed-planting implement. Furthermore, the system may include a controller communicatively coupled to the sensor. As such, the controller may be configured to monitor the residue characteristic associated with the portion of the field within the detection zone based on data received from the sensor. Additionally, the controller may be further configured to control the operation of the residue removal device based on the monitored residue characteristic.

A planting unit includes a seed meter for singulating and dispensing seed. Opening wheels or discs are included to create an opening in the field, such as a furrow. The unit includes one or more continuous tracks for supporting the row unit as it moves through the field. The tracks can be positioned on opposite sides. The tracks reduce compaction around the created furrow and provide better control of seed depth placement. One or more motors are included to operate the tracks to move the planting unit through a field for planting independent of a tow vehicle.
