An agricultural row unit includes a knife disposed ahead of the gauge wheel for delivering material to soil adjacent to a trench. In one example, an agricultural toolbar includes a frame, a wheel mounted to the frame, and a knife disposed ahead of the wheel and comprising a material delivery conduit disposed on, through, or adjacent the knife.

Locations of seeds in a field can be identified using event-based processing or frequency-based processing. A material is applied to the field, based upon the seed locations.

A plough assembly (100) to be mounted on a beam (10) to be moved in a longitudinal forward direction (12) over a soil layer, having a soil surface, to be worked by the assembly (100), the assembly (100) including: a digging shank (110) to extend downwardly into the soil layer; a digging point (120) having a lowermost extremity (122) and to be fixed to a lower portion (112) of the shank (110); a pivotable connector (130) to connect the digging shank (110) to the beam (10); a fluid cylinder (140) mounted across the pivotable connector (130) such that pivoting of the shank (110) causes movement of the cylinder (140), the cylinder (140) being connected to a plough fluid line (150); a pressure reducing valve (160) connecting the plough fluid line (150) to a fluid circuit (170), the pressure reducing valve (160) being adapted to release fluid pressure from the plough fluid line (150) to the fluid circuit (170) at a pre-determined over-pressure point.

In one aspect, a system for controlling the operation of a seed-planting implement may include a furrow-forming tool configured to form a furrow in soil present within a field. Furthermore, the system may include a sensor configured to capture data indicative of a topographical profile of the soil within the field. Additionally, a controller of the disclosed system may be configured to identify a topographical feature within the field based on the data received from the sensor. Furthermore, the controller may be configured to determine a position of the furrow-forming tool relative to the identified topographical feature. Additionally, the controller may be configured to initiate a control action to adjust the position of the furrow-forming tool when it is determined that the relative position between the furrow-forming tool and the identified topographical feature is offset from a predetermined positional relationship defined for the furrow-forming tool.

A control system for a tillage implement broadly includes front and rear sensors, a leveling assembly, and a controller. The front sensor is positioned on a front of a central section, wherein the front sensor is configured to obtain height information indicative of a height of the front of the central section above a ground. The rear sensor is positioned on a rear of the central section, wherein the rear sensor is configured to obtain height information indicative of a height of the rear of the central section above the ground. The leveling assembly is configured to adjust a front to rear orientation of the central section. The controller is configured to receive the height information from the front sensor and the height information from the rear sensor, and to provide instructions to the leveling assembly to adjust the front to rear orientation of the central section based on the received height information.

A seed coulter arranged to place one or more inputs in a groove behind a tine of a direct seed drill for field crops. The seed coulter is arranged for displaceable connection to the tine and is freely displaceable in the longitudinal direction of the tine between a lower position and an upper position. A seeding unit comprising the seed coulter, and a direct seed drill comprising a plurality of seeding units are described as well.

In one aspect, a method for monitoring seed placement within the ground during the performance of a planting operation includes receiving, with a computing device, a timing signal associated with a detection of a seed to be deposited within soil by a row unit as the row unit is actively depositing seeds within the soil, and identifying, with the computing device, a time associated with when the seed will pass through a detection zone of a seed placement sensor supported relative to the row unit based on the timing signal, the seed placement sensor configured to detect the seed as planted underneath a surface of the soil. In addition, the method includes evaluating, with the computing device, data collected by the seed placement sensor during the identified time to determine a seed placement parameter associated with seed.

A conveyor apparatus includes a conveyor sloping upward from a lower conveyor intake to an upper conveyor discharge and with a downspout extending down from the conveyor discharge. Wheels support the conveyor for movement along the ground, and a downspout control is operative to remotely move a bottom end of the downspout radially with respect to the conveyor discharge. A method is provided as well for using the conveyor to conveniently transfer a first agricultural product from a first transport vehicle to a first tank on the air seeder cart, and for transferring a second agricultural product from a second transport vehicle to a second tank.

A method of controlling the downpressure on an air seeder that has a plurality of seed assemblies and a plurality of fertilizer assemblies each applying an adjustable downforce, wherein the method includes keeping a total downforce applied by all of the plurality of seed assemblies and all of the plurality of fertilizer assemblies less than a maximum downforce. The method may also include keeping the downforce applied by each of the fertilizer assemblies less than the downforce applied by each of the seed assemblies.

Systems, methods, and an apparatus for distributing starter fertilizer during the planting process. In an embodiment, a starter fertilizer system is configured to apply fertilizer to a planted seed during a planting process. The starter fertilizer system includes a rudder blade, a fertilizer reservoir and a conduit. The rudder blade is configured to the dig a furrow that is offset from the planted seed. The conduit is coupled with the fertilizer reservoir and the rudder blade such that fertilizer is able to traverse from the reservoir to the rudder blade. The rudder blade is offset from each row unit such that fertilizer is expelled at a desired fertilizer location.
