Abstract: A pneumatic on-demand seed delivery system wherein seed from the auxiliary hopper enters the seed meter through an opening beginning rearward of the vertical axis of the seed meter. And a retrofit kit for existing on-demand seed delivery systems, and method of retrofitting such existing pneumatic on-demand seed delivery systems, so as to provide an auxiliary hopper that communicates seed to the seed meter through an opening beginning rearward of the vertical axis of the seed meter.

Abstract: Systems, methods and apparatus for monitoring yield while harvesting. In one embodiment a mass flow rate sensor measures the mass flow rate of the harvested grain. A weight sensor measures the weight of the harvested grain. The measured mass flow rate is correlated with the weight of the harvested grain. Processing circuitry calculates any error in the measured mass flow rate using the measured weight. The calculated error is used to correct any inaccuracy in the measured mass flow rate.

CPC classification number: A01C7/046
Abstract: A seed singulator for use with a vacuum disk having a seed face and a shoulder. The seed singulator has a first member and a second member supported by biasing members. The first member has upper lobes disposed at a radius of curvature slightly less than the outside radius of a row of apertures on a seed plane of the vacuum disk. The seed member has lower lobes disposed at a radius of curvature slightly greater than the inside radius than the row of apradius. The biasing members permit the lobes to move with the seed plane and the shoulder as the vacuum disk rotates thereby maintaining their position with respect to the apertures.

Abstract: A dynamic supplemental downforce control system for a planter row unit. The system includes closed-loop feedback circuit that cooperates with a downforce actuator to dynamically control fluid flow to the downforce actuator to maintain balance between the actual gauge wheel downforce and a desired gauge wheel downforce during planting operations.

Abstract: A load sensing pin disposed to receive a load applied in a direction substantially transverse to a longitudinal axis of the pin. A load sensor is substantially fixedly oriented with respect to the applied load or alternatively with respect to the pin which is rotationally restrained with respect to a support structure. The load sensor is disposed to generate a load signal corresponding to strain of the pin resulting from the applied load.

Abstract: A seed meter for an agricultural planter in which the seed disc is rotatably mounted within a seed meter housing. As the seed disc rotates, the apertures in the disc rotate along a seed aperture path through a horizontally adjacent seed pool area. The seed disc includes cavities disposed along the seed aperture path to agitate the seeds in the seed pool area. A singulator having multiple co-planar singulator surfaces is biased against the seed side surface of the seed disc.

Abstract: Systems, methods and apparatus for controlling the downforce applied to a row unit of an agricultural implement having multiple row units. A downpressure control device in fluid communication with a down chamber of the least one actuator maintains as a selected downpressure, any one of a continuous range of pressures in the downpressure chamber. A lift pressure control device in fluid communication with a lift chamber of the at least one actuator for controlling pressure in the lift chamber maintains as a selected lift pressure, any one of a continuous range of pressures in the lift chamber.
