Abstract: The devices, systems, and methods herein use air pressure to dispense seed into the ground in a controlled manner. In certain embodiments, a valve is actuated to push a single seed out of a seed chamber. The seed can be conveyed from the metering housing and through a seed delivery apparatus to the furrow at high speed. The seed is rapidly conveyed from the seed chamber to the furrow by a precisely controlled air pulse to eliminate variation enable high planting speeds.

Abstract: A product flow splitter is used to distribute agricultural product from a distribution line to a primary hopper and a secondary hopper. The splitter has an inlet segment, a primary outlet segment, and a secondary outlet segment. The inlet segment receives the agricultural product from the distribution line, the primary outlet segment outputs the agricultural product to the primary hopper, and the secondary outlet segment outputs the agricultural product to the secondary hopper. The primary outlet segment is aligned with the inlet segment along a common axis and the secondary outlet segment is curved to avoid plugging of the agricultural product in the product flow splitter. The primary outlet segment is positioned relative to the primary hopper so that an outlet of the primary outlet segment in the primary hopper is offset from an outlet of the primary hopper to a meter system to solve an overfilled situation.

Abstract: An agricultural seed planter is provided. The agricultural seed planter has a large diameter rotating planting wheel with fingers or teeth spaced around the periphery of the planting wheel. The teeth are positioned so as to achieve a spacing of the seeds when planted in the soil. The teeth have a small dimple in the end and an even smaller hole passing through the entire length. The dimple provides a place for the seed to sit in and the small hole allows positive or negative air pressure to be transmitted to the seed. The negative air pressure creates a vacuum suction that attaches the seed to the teeth, and the positive air pressure releases the seed from the teeth. In an example implementation, the wheel includes many individual mechanical modules that are linked together to form the wheel.

Abstract: A method includes the step of receiving a first weight value from a sensor associated with a feed mixer. A first rotation speed associated with the first weight value is monitored. A second weight value is received from the sensor associated with the feed mixer and a second rotation speed associated with the second weight value is monitored. A mixing profile is generated based on the first weight value, the second weight value, the first rotation speed, and the second rotation speed. In one embodiment, a first feed ingredient is associated with the first weight value and a second feed ingredient is associated with the second weight value.

Abstract: Metering devices for an agricultural implement apply a field input, for example, pneumatically delivered granular product including seed or fertilizer or sprayed liquid product including fertilizer and the like, to an agricultural field. In the applying of the field input, the rate of application of the dispensers of one section of the implement can be collectively varied in relation to the rate of application of the dispensers of a different section of the implement frame.
