The present invention is a row cleaning device having a main body with a proximal end and a distal end, the main body proximal end is adapted to mount to a seeder. A pivot leg has a first end and a second end, the first end is pivotally mounted to the main body distal end at a pivot, the second end extends toward the main body proximal end. A clearing implement is mounted to the pivot leg second end and rotates with respect to the pivot leg. The row cleaning device is adapted to be driven by a seeder in a direction of travel with the clearing implement being located behind the pivot in the direction of travel. The pivot leg pivots with respect to the main body as the clearing implement moves along the ground in the direction of travel.

Systems, methods and apparatus for adjusting the depth of a trench opened by a row unit of an agricultural planter. The row unit includes a trench depth adjustment assembly configured to modify the furrow depth. In one embodiment, the depth adjustment assembly may include a gear box having one or more gears which engage with a gear rack. The gear box may be pivotally connected to a depth adjustment body supporting a rocker that adjusts upward travel of gauge wheel arms. In another embodiment, the depth adjustment assembly may include a depth adjustment arm having a screw receiver that cooperates with a driven screw that adjusts the position of the depth adjustment arm acting on the gauge wheels to adjust trench depth.

An agricultural planter includes systems, methods, and apparatuses for maintaining down force pressure at row units of the planter. The row units may include an electric linear actuator connected to linkages of the row units to maintain a down force pressure for the row unit. The linkage may also be removed and replaced with a strut or like mechanism to apply a direct down force pressure to components of the row unit. One or more sensors can be included to obtain information related to the ground to automatically adjust the amount of down force provided based upon a ground characteristic in order to maintain a substantially uniform furrow depth.

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.

A ground opener for an agricultural implement. The ground opener comprising an opening disc, and a support assembly securing the opening disc to the agricultural implement. The support assembly comprises an upper bar, a lower bar, a forward bar, and a rearward bar. At least a portion of each of the bars is orientated at an offset angle with respect to a direction of travel of the agricultural implement.

An agricultural implement wear monitoring system that monitors a first component of an agricultural implement. A sensor detects and emits a signal indicative of a first geometric dimension of the first component and/or a second geometric dimension of the first component relative to a second component. A controller couples to the sensor. The controller monitors the first geometric dimension and/or the second geometric dimension, and in response to a detected change in the first geometric dimension and/or the second geometric dimension determines a remaining service life of the first component.

A fully-automatic transplanting combined machine includes a traction apparatus, operation apparatus and a control system. The operation apparatus is mounted on the traction apparatus with a main body frame and is towed behind the traction apparatus. The operation apparatus includes a rotary tillage furrowing system, a system for slightly preparing soil and opening narrow furrows, a planting system, and a soil covering compacting system which are arranged successively from front to back. The planting system includes more than one planting unit. The fully-automatic transplanting combined machine is capable of orderly performing rotary tillage, cleaning stubble, leveling a border check, opening a furrow, cutting narrow slits, transplanting, covering soil, compacting soil in untilled soil at one process, so as to create the soil requirements for high-speed transplanting of blanket seedlings such as rape and other crops.

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.

The invention relates to a soil cultivation arrangement (100), in particular a soil preparation arrangement, for the agricultural cultivation of a soil (500), in particular a field and/or arable land, with a carrier device for attaching to an agricultural tractor and with one or more soil cultivation units (200, 201, 202, 203) for preparing and/or generating a seed furrow (530), which soil cultivation units (200, 201, 202, 203) as modular components of the soil cultivation arrangement (100) can be connected to the carrier device as required and can be arranged along the carrier device in the desired sequence. At least one soil cultivation unit (200) has a runner-like sliding device (400), the underside of which, as sliding surface (410) facing the soil (500), is designed to slide on a soil surface (510).

A gauge wheel (1) for use in controlling the depth of a furrow formed by at least one planting member of cultivation equipment includes a hub member (5) having a central hub and an outer peripheral portion (9); and a resilient coil member (3). The resilient coil member (3) includes a plurality of coil windings (17) which extend closely adjacent to the outer peripheral portion (9) of the hub member (5) and which define an outer periphery of the gauge wheel (1). The coil member (3) is connected at or adjacent one end thereof to the hub member (5). In use, the resilient coil member engages the soil on a side of the furrow and controls the depth by which the at least one planting member cuts into the soil to form the furrow. There is also provided a coulter gauge wheel which includes a coulter disc and at least one gauge wheel as described above.
