An improved row cleaning/closing wheel having improved debris removing and/or furrow closing performance with complimentary left and right cleaning/closing wheel pairs having complimentary teeth configurations to provide spatial, angular and rotational intermeshed cleaning and/or closing operation during row planting. The improved row cleaning wheel for use with a floating row cleaner and/or closing arm assemblies attached to a row planter during planting operation.

A disc holder and scraper construction for disc harrows comprises a disc element fixed to a rotary hub, which is supported by a disc holder spring in turn fixed to a framework of a disc harrow, the disc holder construction further comprising a scraper assembly for removing soil adhering to a disc element, the scraper assembly being affixed to a flexible disc scraper arm, which is in turn affixed to the disc holder spring; the disc scraper arm, affixed to the disc holder spring and not to the harrow framework, supports the scraper assembly and is driven in a timed manner with respect to the disc element.

A tilling implement includes a frame, a row of disc blades coupled to the frame, and a soil finisher coupled to the frame. The soil finisher includes multiple chopper blades, each chopper blade of the multiple chopper blades includes multiple fins that extend radially from a hub, a first set of the multiple fins bend in a first direction relative to the hub, and a second set of the multiple fins bend in a second direction relative to the hub to facilitate tossing soil as the tilling implement travels through a field.

A ground engaging agricultural blade, coulter, or disc having a central opening adapted to be attached to an implement for rotation about a substantially horizontal axis of rotation; the coulter or disc have an outer periphery; and plurality of step plane notches disposed in the outer periphery. The blade can be used with a hub disposed around the central opening or a spacer spool on a shaft extending through the central openings of adjacent blades, the spacer spools extending radially outwardly by a distance.

Disclosed is a sowing coulter arrangement comprising a suspension device for mounting the sowing coulter arrangement on a machine frame; a coulter frame connected to the suspension device for mounting components of the sowing coulter arrangement thereon; and a coulter disk. The arrangement further comprises a furrow closer pivotally mounted on the coulter frame; a metering device for dispensing the material to be distributed; a seed tube for transporting the material to be distributed from the metering device to a seed furrow; and a catching element for catching the material disposed downstream of the outlet of the seed tube. The metering device, the seed tube, and the catching element form a unit and are mounted on a carrier that is pivotably affixed to the coulter frame, whereby an arrangement of an outlet of a seed tube in relation to a catching element is at all times kept largely constant.
