A seed delivery apparatus and methods in which a seed conveyor delivers seed from a metering device to a furrow in a controlled manner to maintain seed placement accuracy within the furrow.

A seed research plot planter includes a rotating seed plate for picking up and transporting seeds from a seed chamber to a release point, and a sensor that detects the rotational position of the seed plate. A distance measuring device measures a distance traveled by the planter. A controller uses a first signal from the sensor and a second signal from the distance measuring device to control a sequence of operations of the planter based on the rotational position of the seed plate and the location of the planter within the field. A field layout system is provided for creating a plot field layout having a desired number of ranges, a desired number of planter passes, and desired parameters for each plot within the field. The field layout system allows different plot lengths and seed populations to be input for individual plots within the same planter pass through the field.

An agricultural metering system includes multiple independently controllable sets of meter rollers. Each set of meter rollers includes at least one meter roller, each set of meter rollers is configured to rotate about a respective rotational axis, the rotational axes are generally perpendicular to a common plane, and the rotational axes are offset relative to one another in the common plane. The agricultural metering system also includes multiple meter boxes configured to receive agricultural product from a storage tank. Each set of meter rollers is disposed within a respective meter box, and each set of meter rollers is configured to meter the agricultural product from the storage tank. In addition, the agricultural metering system includes multiple distribution lines. Each distribution line is disposed downstream from a respective set of meter rollers and configured to receive the agricultural product output from the respective set of meter rollers.

Systems, methods and apparatus are provided for entraining seed into a plurality of seed supply lines. Some embodiments enable selective prevention of seeds from entering a subset of seed supply lines. Some embodiments enable improved flow of seed through an entrainer by angled surfaces provided on blocking members disposed to selectively block seed from entering seed supply lines.

A wheel for a lawn mower robot includes a structure in which grass seeds can be discharged during a rotation of the wheel. Accordingly, grass seeds are shown as the lawn mower robot travels while performing a lawn mowing task. Therefore, a task of mowing the lawn and a task of sowing seeds can be performed in a unified manner. Thus, the lawn can be managed more efficiently.

A seed delivery apparatus and methods in which a seed conveyor delivers seed from a metering device to a furrow in a controlled manner to maintain seed placement accuracy within the furrow.

A seed dispersion unit for distributing a plurality of seeds includes a single inlet for the plurality of seeds, a chamber in communication with the single inlet, and a plurality of outlet conduits in communication with the chamber. Each of the plurality of outlet conduits is configured to transfer a portion of the plurality of seeds from the chamber. An annular base defines a portion of the chamber. Each of the outlet conduits extends radially from the base.

An agricultural seeding machine comprises, in one example, a seed delivery system configured to deliver seeds to at least one trench by two or more substantially gravity-drop channels, and a seed metering system comprising a rotating meter element configured to singulate seeds from a seed source into the two or more channels.

A depth adjustment for an agricultural seed planting implement has a depth control assembly of side by side gauge wheels pivotally mounted to a frame with leading equal length arms in a staggered relation. A settable lever acts on the arms through a control rocker having arms with the same staggered relation to control soil flow.
