Abstract: An agricultural trench depth sensing system having a trench implement adapted to be disposed in a soil trench opened in a soil surface. In one embodiment an ultrasonic sensor detects a distance to an upper surface of said trench implement or a target disposed thereon. In another embodiment, said trench implement includes one or more fingers which rotate with respect to said trench implement to detect the soil surface relative to said trench implement. In another embodiment, said trench implement includes side sensors for detecting the sidewall of the soil trench.

Abstract: A sowing coulter for direct and/or mulch sowing includes a coulter body, a tear-open chisel fastened by a fastening device, and coulter blades laterally projecting from the tear-open chisel and provided with front cutting edges, which are arranged in order to create a sowing furrow in the ground. In order to change the penetration depth of the sowing coulter into the ground, the coulter blades are adjustable about a horizontal axis that extends transversely to the direction of travel, and that is fixable in different positions by way of an adjustment device arranged between the tear-open chisel and the coulter body.

Abstract: A system for controlling an operation of a seed-planting implement includes a row unit frame and a residue removal device pivotably coupled to the row unit frame. Furthermore, the system includes a first sensor configured to capture data indicative of a position of the residue removal device relative to the row unit frame. Additionally, the system includes a computing system communicatively coupled to the first sensor, with the computing system configured to determine the position of the residue removal device relative to the row unit frame based on the data captured by the first sensor. Moreover, the computing system is configured to determine a field condition of a field across which the seed-planting implement is traveling based on the determined position of the residue removal device.

Abstract: Described herein are air seeders that have force actuators acting on at least one of the firming implement and closing wheel to adjust for a specified downforce on at least one of the firming implement and the closing wheel. In one example, a seeding implement includes a support arm having a support arm first portion and a support arm second portion. A firming implement support arm is pivotally connected to the support arm second portion at a first pivot at a first end of the firming implement support arm. A firming implement force actuator is pivotally connected to the support arm second portion at a first end of the firming implement force actuator and connected to the firming implement support arm at the second end of the firming implement force actuator.

Abstract: A dual-disk seed meter for a planter may include a housing defining a first seed chamber configured to receive first seeds of a first seed type and a second seed chamber configured to receive second seeds of a second seed type. The seed meter may also include a first seed disk rotatable within the housing to convey the first seeds from the first seed chamber, a second seed disk rotatable within the housing to convey the second seeds from the second seed chamber, and a drive assembly configured to simultaneously rotate the first and second seed disks. In addition, the seed meter may include a seed deflector movable relative to the first seed disk and/or the second seed disk to control which of the seed types is discharged from the housing based on a selected seed type to be delivered by the seed meter.

Abstract: In one aspect, a system for spraying a fluid onto or near seeds may include a planter having a seed meter configured to dispense seeds from a hopper, a seed tube extending from the seed meter toward a furrow, and a rotationally-driven belt positioned within the seed tube. The belt may be configured for conveying the seeds from the seed meter through the seed tube to the furrow. The planter also includes a sprayer assembly having a nozzle configured to spray a fluid on or near the seeds dispensed from the seed meter. The system may further include a controller configured to determine a current speed of the belt relative to the seed tube and control the sprayer assembly based on the current speed of the belt such that the nozzle sprays the fluid at least one of onto or near each of the seeds.

Abstract: An arrangement for detection of the amount of material in a supply container of a machine for application of material to a field comprises a data entry device for receiving fill level data concerning an amount of material present in the supply container at a specific time point and an outflow sensor for detection of the amount of material that has flowed out of the supply container. A computer device connected to the data entry device and outflow sensor, the computing device is programmed to calculate the current amount of material in the supply container using the obtained fill level data and the signals of the outflow sensor obtained after the specific time point, and to issue a warning signal if the amount of material in the supply container goes below a predetermined level.

Abstract: A crop input applicator is provided. The crop input applicator monitors the presence of applied liquid crop in a seed trench and/or the relative placement of liquid crop and seed in a seed trench. In another aspect, the crop input applicator minimizes an offset between the liquid crop and seed placement.

Abstract: A trailing assembly for an agricultural planter is attached to a frame element of the agricultural planter with a mounting bracket. A walking beam having a hub at an intermediate position along a length of the walking beam is pivotably attached to the mounting bracket. A first pair of arms extends from the hub in a first direction, with each arm configured with a shaft to rotatably and selectively receive a first rotating implement, for example, a closing wheel or a fertilizer opener disc. A second pair of arms extends from the hub in a second direction parallel to each other and spaced apart from each other. Distal ends of the second pair of arms are configured to rotatably and selectively receive and support opposing ends of an axle of another rotating implement, for example, a press wheel, positioned between the second set of arms.
