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.
Abstract:
Systems, methods and apparatus for detecting stalks processed by a combine harvester, for measuring stalk diameters, and for displaying harvest metrics and yield data to a user based on stalk locations and stalk diameters.
Abstract:
A variable pressure control system for varying pressures in the fluid circuits of a dual acting actuator over a range of pressures. The variable pressure control system includes a controller that cooperates with pressure regulators for regulating the desired pressure in the fluid circuits.
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:
Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts through-out the several views, FIG. 1 illustrates a prior art agricultural combine 10 which is supported and propelled by ground engaging wheels 14. Although the combine 10 is illustrated as being supported and propelled on ground engaging wheels 14 it can also be supported and propelled by full tracks or half tracks. A harvesting assembly 16 is used to gather crop and to conduct it to a feederhouse 18. The crop is conducted by the feederhouse 18 to a beater 20. The beater 20 guides the crop upwardly through an intake transition region 22 to a rotary threshing and separating assembly 24. In addition to rotary type combines such as that illustrated in FIG. 1, the prior art includes conventional combines having a transverse threshing cylinder and straw walkers or combines having a transverse threshing cylinder and rotary separator rotors.

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:
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.
