Abstract: A vehicle includes a frame, a plurality of tanks supported on the frame and housing particulate, an unloading system, a lifting mechanism, and a positioning system. The unloading system includes a plurality of individual carriers, each of which corresponds to one or more of the tanks. Each of the carriers defines a discharge opening for dispensing particulate unloaded from one or more of the tanks. The carriers are mounted to the frame such that the carriers are supported independently of the tanks. The lifting mechanism includes a shiftable positioning rail that at least partially supports each of the carriers, with generally vertical shifting of the positioning rail simultaneously raising or lowering each of the discharge openings. The positioning system includes a plurality of positioning devices, with shifting of each of the positioning devices resulting in fore-and-aft shifting of the corresponding one or more of the discharge openings.

Abstract: A mobile air cart includes a metering assembly configured to receive particulate from a tank and to deliver particulate to pneumatic conveying lines. The metering assembly includes wall structure that defines a unitary, common metering chamber. The metering assembly further includes a plurality of meter units. The meter units are configured to meter and separate particulate within the chamber into respective particulate flows corresponding to the conveying lines.

Abstract: An improved collector assembly comprises a generally hollow body mounted below a product supply tank for receiving plural streams of materials metered from the tank. Individual upright passages through the body corresponding in number to the metered streams from the tank receive the gravitating product streams and direct each stream into either or both of an upper loading zone and a lower loading zone in the passage. A diverter valve associated with each upper loading zone can be set to close off the upper loading zone entirely while opening only the lower zone or closing off the lower loading zone while opening only the upper loading zone. Thus, air streams passing transversely through the upper and lower loading zones respectively can be supplied with variable amounts of metered product, depending upon the position of the diverter valve within each passage.

Abstract: An agricultural implement useful to prepare the ground before or after a seeding operation includes a number of soil packer units which are directly coupled to transversely extending tool bars or frame members ahead of respective, trailing harrow sections. The packer units are connected to the frame members by relatively short links for free up and down shifting movement during advancement of the implement across the field in substantial independence of vertical movement of the harrow sections. The frame members are pivotal about a parallel, horizontal axis to raise the harrow sections and the packer units to an upright orientation for transport, at which time a portion of the links supporting the packer units comes into firm, resting contact with a stop for precluding further movement of the packer units.

Abstract: The air seeder normally passes the contents of its hopper through metering devices that regulate the volume of materials moving into the transporting air streams of the machine, but the hopper is also provided with a series of normally closed drainage apertures which may be selectively opened when it is desired to rapidly dump the hopper contents instead of relatively slowly metering them to the air streams. When the apertures are opened, the hopper contents bypass the metering devices and gravitate directly into the air streams which can be quickly and easily diverted to a cyclone separator that exhausts the air from the streams and concentrates the particles for collection or storage.
