    摘要： 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.

    摘要： 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.

    摘要： 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.
