A seed metering assembly for a farm implement has a meter roller that can be accessed and removed in a relatively quick manner. The seed metering assembly includes a fluted meter roller that is segmented into a number of discrete fluted sections. Each fluted section has an associated flow control member that is selectively operable to impede the flow of granular material from a seed hopper to its corresponding section of the fluted meter roller.

A seeding machine includes at least one seed metering system and at least one seed placement system. Each seed placement system is in communication with a corresponding seed metering system. Each seed placement system includes a housing having a seed slide, and a wheel at least partly disposed within the housing. The wheel has a circumferential periphery with a plurality of contiguous disc joint surfaces. The periphery is positioned adjacent to at least part of the seed slide. The invention comprises, in another form thereof, a method of placing seeds with a seeding machine in a trench formed in soil. Seeds are received at a predetermined rate at a seed placement system. The seed placement system includes a seed slide, and a wheel having a conferential periphery position closely adjacent to at least part of the seed slide. The seeds are engaged at the predetermined rate against the wheel periphery. The seeds are carried past a closely adjacent area of the seed slide using the wheel periphery. The seeds are released from the wheel periphery.

A singulating disc, carried by a housing, has a plurality of openings around its periphery. The disc rotates vertically through a pickup chamber of a hopper carried by the housing. A vacuum is pulled through the openings by a pump which is connected to the disc. Items are placed in the hopper and, via gravity, fall to the bottom of the hopper where they contact the periphery of the rotating disc. The vacuum at the openings attaches an item and holds it while the disc rotates. At the top of the disc's rotation, a diverter directs the item into a path depending on the results of a fragment detection and/or counting mechanism. Items that are allowed to pass by the diverter are scraped off the disc into another path by a scraper. Negative pressure is used to singulate and count a multitude of sizes and shapes of items with no calibration. Retractable paddles, a vacuum management system, and RFID tags may be incorporated. The paddles aid in the pickup and agitation of the items while the vacuum management system conserves the vacuum capacity necessary to pickup and singulate items. The RFID tags may contain information such as the number of items left in the hopper, a par level for that item, an expiration date, among others. Because of the rules governing abstracts, this abstract should not be used to construe the claims.

An agricultural row unit includes a towing frame, an attachment frame, and a linkage. A row unit frame has a forward end coupled to the linkage to permit vertical pivoting movement of the row unit frame relative to the attachment frame. A closing-wheel assembly includes a support arm having a leading end coupled to the row unit frame, and a hub assembly mounted at a trailing end of the support arm. The hub assembly has a wheel-fastening mechanism with one or more removable fasteners. The closing-wheel assembly further includes a closing wheel connected to the hub assembly with the one or more removable fasteners such that the closing wheel is interchangeable with different types of modular closing wheels.

The transversely extending frame of a machine has a number of hingedly interconnected frame sections that may be raised and lowered by lift cylinders to convert the machine between a wide-spread working position and a folded-up transport position. Two lift cylinders for raising and lowering inner wing frame sections relative to the central main frame section are anchored at their inner ends to a hydraulically operated holding cylinder that effectively adjusts the positions of the anchor points of the lift cylinder in a lateral sense. Thus, when the holding cylinder is fully contracted, the inner wing frame sections may be lowered by their lift cylinders until the lift cylinders are fully extended, but the outer ends of the inner wing frame sections remain tilted upwardly to a certain extent. Thus, outer wing frame sections connected to the outer ends of the inner wing frame sections also remain slightly lifted off the ground until fully unfolded from the inner wing frame sections. Thereupon, the holding cylinder may be extended to gently lower all wing frame sections to the ground without damaging tools or mounting components for such tools.

A seed delivery system is provided that includes a row crop seed planter having a seed meter that can pneumatically deliver seeds to the agricultural field at a rearward velocity that matches a forward velocity of the planter. The seed meter may include a positive pressure source that pressurizes the seed meter and creates an airflow out of a seed tube of the seed meter that carries the individual seeds out of the seed tube at a rearward velocity that is automatically adjusted to match a forward velocity of the seed planter and tractor.

In one embodiment, an agricultural row unit for use with a towing frame hitched to a tractor includes an attachment frame adapted to be rigidly connected to the towing frame. A support member is pivotably coupled to the attachment frame to permit vertical pivoting movement of the support member relative to the attachment frame, and at least one furrow-closing device is mounted on the support member. A hydraulic cylinder is coupled to the support member for urging the row unit frame downwardly toward the soil. The hydraulic cylinder includes a movable ram extending into the cylinder, and a hydraulic-fluid cavity within the cylinder for receiving pressurized hydraulic fluid for urging the ram in a first direction that pivots the support member in a first vertical direction. An accumulator has a fluid chamber containing a pressurized gas for urging the ram in a second direction that pivots the support member in a second vertical direction.

A pivot assembly for attaching a closing wheel arm to a bearing housing of a no-till drill has a pair of sleeve bearings, a pair of seals, and a pivot bushing or pivot pin that extends through the sleeve bearings and seals. The sleeve bearings are press fit into opposite ends of a bore of the bearing housing and have grooves formed across bearing surfaces thereof for grease to flow to outer ends of the bearings. The seals are also press fit into the opposite ends of the bearing housing bore. The pivot bushing or pivot pin is installed into the sleeve bearings with an outer surface thereof providing a close-running fit with the bearing surfaces of the sleeve bearings. The close-running fit has a clearance within the range of 0.001 to 0.002 inch and can be provided by passing a reamer through the inner bore of the sleeve bearings.

An agricultural implement is provided that includes a number of row units. The row units include one or more seed meters for receiving, singulating, and dispensing seed to the ground such that preferred spacing of subsequent seed is attained. Seed delivery systems are included to aid in transporting the seed from the seed meter to the ground in a controlled manner to mitigate skips and to aid in controlling the spacing of the seeds, which can be based upon the ground speed of the implement as it moves through the field. The seed delivery systems can control the transport of the seed to a furrow in the field such that the seed can experience zero or near zero relative velocity so that the seed will have little to no movement once positioned in the furrow.
