A work vehicle includes a commodity container and an actuator system with a plurality of actuators. The work vehicle includes a delivery system with a plurality of tubes. Furthermore, the work vehicle includes a metering system with a plurality of metering rollers that are configured to be individually actuated by respective ones of the plurality of actuators to meter out a commodity from the commodity container to respective ones of the plurality of tubes. The plurality of metering rollers are arranged substantially parallel to each other. The plurality of metering rollers are disposed in a staggered arrangement.

An agricultural metering system includes independently controllable meter rollers, in which each meter roller is configured to rotate about a respective rotational axis. The agricultural metering system also includes meter boxes configured to receive agricultural product from a storage tank. Each meter roller is disposed within a respective meter box, and each meter roller is configured to meter the agricultural product from the storage tank. In addition, the agricultural metering system includes independently controllable motors. Each independently controllable motor is coupled to a respective meter roller, and each independently controllable motor is configured to drive the respective meter roller to rotate.

A pre-metering system for feeding different types of seed into a seed meter of a planter includes separate feeder wheels that are selectively rotated to deliver different types of seed from on-row storage into the seed meter at a given time. The feeder wheels may be supported by a feeder wheel carrier that may also support various wall and ramped structures, such as upright divider walls and sloped walls that maintain separation between the different types of seeds in the on-row storage and direct the different types of seed toward the individual feeder wheels.

An agricultural planting implement 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. A seed meter provides seeds one at time to a seed carrier, such as a brush wheel. The brush wheel may move the seeds one at a time to a seed conveyor by directly moving seeds along a curved portion of a seed disc in the seed meter. The seed conveyor may be a flighted belt, and the velocity of the seeds when transferred from the seed carrier may match the velocity of the flighted belt. The seed conveyor conveys the seeds to a position near the bottom of a furrow, and ejects the seeds with little or no horizontal velocity relative to the bottom of the furrow.

A metering apparatus for distributing an agricultural product in a field has a meterbox configured for association with a hopper for receiving agricultural product from the hopper. A rotatable metering element is disposed within a chamber in the meterbox, and the rotating metering element is configured to deliver the agricultural product at a regulated rate from the hopper through the chamber to a product distribution line. Delivery of the agricultural product to the product distribution line may be selectively stopped by a disengagement structure for disengaging the agricultural product from the meter roller while the meter roller continues to rotate. The disengagement structure may comprise the meter roller moveable between a lowered product engaging position and a raised product disengaging position.

An agricultural metering system includes multiple meter boxes and multiple meter rollers, in which each meter roller is disposed in a respective meter box. The agricultural metering system also includes multiple meter roller sleeves, in which each meter roller sleeve is disposed about a respective meter roller, and each meter roller sleeve is configured to move relative to the respective meter roller to selectively cover a first portion of the respective meter roller and a second portion of the respective meter roller. In addition, the agricultural metering system includes a control bar coupled to the meter roller sleeves. The control bar is configured to collectively move the meter roller sleeves relative to the meter rollers.

An agricultural metering system includes multiple meter boxes and multiple meter rollers, in which each meter roller is disposed in a respective meter box. The agricultural metering system also includes multiple meter roller covers, in which each meter roller cover is disposed over at least part of a respective meter roller, and each meter roller cover is configured to move relative to the respective meter roller to cover a selected portion of the respective meter roller. In addition, the agricultural metering system includes a control bar coupled to the meter roller covers. The control bar is configured to collectively move the meter roller covers relative to the meter rollers.

The invention relates to a metering device (5) for granular material, in particular seeds and/or fertilizer, where the metering device (5) comprises a metering housing (9) having at least one inlet (8) and at least one outlet (11) for the granular material and two side walls (10) that are arranged spaced from one another, where a metering wheel (13) with end faces (13a) each pointing toward the side walls (10) is arranged between, firstly, the inlet (8) and, secondly, the outlet (11), and between the side walls (10), that are arranged spaced from one another, on a shaft and is connectable in a force-fit manner to the latter and can be driven to rotate by the shaft in a metering direction (D), where the metering wheel (13) is associated with blocking means (14) which are configured to block the metering wheel (13) against the transport of granular material in a direction opposite to the metering direction (D) from the inlet (8) to the outlet (11) and/or in the metering direction (D) from the outlet (11) to the inlet (8), and a plain wheel (15) is arranged at each end face (13a) of the metering wheel (13) and extends between the end face (13a) and the side wall (10) in an unfastened manner on the shaft, where a sealing element (16) is arranged on both sides between the respective end face (13a) of the metering wheel (13) and a side surface (15a) of the respective plain wheel (15) pointing toward this end face (13a).
