Seed meter singulator

A seed meter includes a meter housing having a first chamber for seeds and a second chamber. A seed disk is rotatably supported within the meter housing and has a first side and a second side. The first side is exposed to the first chamber and the second side is exposed to the second chamber. The seed disk includes a plurality of seed openings that extend between the first and second sides at a predetermined radial position. A singulator is positioned against the first side of the seed disk and has at least one structure for removing excess seeds from the seed openings as the seed meter disk rotates relative to the singulator. A radial position of the singulator is controlled at least in part by a hub portion of the seed meter. A biasing spring is positioned to exert an axially-oriented bias force pressing the singulator against the first side of the seed meter disk.

10986763 · 2021-04-27 ·

An agricultural planter and tractor combination which has a connection therebetween which comprises a stationary support arm coupled to the tractor and a pivoting support arm coupled to the agricultural planter with a connecting threaded member extended therethrough and a rotation-limited intermediate member with two protrusions extending into voids in the pivoting support arm so that the pivoting support arm will not rotate around the connecting threaded member and the connecting threaded member further translated through a portion of a hex-headed bushing and rotationally advanced through another portion, and a terminal nut also rotationally advanced over the connecting threaded member. The rotation-limited intermediate member is made of a harder more durable material than the connecting threaded member, the stationary support arm and the pivoting support arm.

In an example embodiment, a system includes a motor, a memory storing instructions and at least one controller configured to execute the instructions to cause the system to obtain at least one message over a network, the at least one message indicating a target position for a rotor of the motor and a target time associated with the target position, determine a position command and a speed command based on the target position and the target time, and control the motor based on the position command and the speed command.

Work vehicle with row unit having variable steering angle

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 product distribution system mounting assembly includes a first member configured to rigidly couple to a frame of an agricultural apparatus and a second member configured to rigidly couple to a plurality of tubular components of a product distribution system of the agricultural apparatus. The first member and the second member are configured to engage with one another to form a sliding interface that enables the plurality of tubular components to move along a vertical axis relative to the frame as the agricultural apparatus moves in a direction of travel through a field.

Agricultural Operation Monitoring Apparatus, Systems, And Methods

A system is provided for measuring soil properties. The system includes at least one sensor coupled to a row unit of an agricultural implement and a camera coupled to the row unit of the agricultural implement. The at least one sensor is configured to measure at least one soil property of soil worked by the row unit and/or of soil in a trench opened by an opening assembly of the row unit. And, the camera is arranged, on the row unit, to capture images of the soil worked by the row unit and/or the trench opened by the opening assembly of the row unit.

Openers for seeders

Openers for a seeder, configured to be adjustably engaged with a soil surface when in use; each opener having compliance to vertical and lateral excessive forces independently applied to soil-engaging parts: a fertiliser tine, a seed tine, a press wheel, a coulter, and a support wheel. The openers share a hydraulic circuit, linked to each internal frame-lifting ram so that localised rise and fall effects arising from soil surface irregularities are shared, maintaining a mean height. The seed tine of each opener is mechanically coupled to the preceding fertilizer tine and is lifted when the fertilizer tine is displaced. The openers do not require external weight support.

Sowing coulter arrangement of an agricultural machine
10952368 · 2021-03-23 · ·

A sowing coulter arrangement comprises 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.

ANGLE ADJUSTMENT DEVICE FOR DISC-TYPE COULTERS

The present invention involves a seed firmer with a pusher attachment that extends the life of the seed firmer and brackets for mounting the same to a planter. The disclosed invention additionally involves an adjustment mechanism for seed or grain drill planters which allows for the adjustment of the camber and/or toe of individual coulters on the planter.

METERING DEVICE FOR AGRICULTURAL PRODUCT

A metering device for dispensing agricultural product from a bin. The metering device comprises an upper housing and a lower housing removably engaged with the upper housings. The metering device further includes at least one metering wheel positioned within an interior space presented by the upper housing or the lower housing.
