Abstract: Provided herein are methods, systems, and devices for flexible and accurate seed spacing control in a seed planting system. The various embodiments receive singulated seed from a metering device and control movement of the seed toward a seed spacing device that receives the seed. The seed spacing device, which is disposed near the soil surface, independently controls the ejection of the seed from the device and thus the spacing of the seed in the furrow.

Abstract: A planter downforce system includes a plurality of hydraulic accumulators. Each of the plurality of hydraulic accumulators is operatively connected to a pressure line associated with a row unit of a planter. A pressure sensor is operatively connected to the pressure line. An orifice is operatively connected to the pressure line to limit flow of fluid within the pressure line to a hydraulic zero-pressure tank. A controller is operatively connected to the pressure sensor and configured to determine accumulator charge pressure of the accumulators.

Abstract: The disclosed apparatus, systems and methods relate to a steerable toolbar. The toolbar is able to rotate relative to the tractor or other driving vehicle to reduce misalignment and/or cross-track error. Actuators can be utilized with draft links to pivot the toolbar around a central pivot point and improve the following path of the toolbar implement.
