Abstract: In an air seeder assembly having a base mount member with a at least one base ear with a base bore, and a seed boot with at least one boot ear with a boot bore, a fastening assembly mounting the seed boot to the base mount member is disclosed. The fastening assembly comprises a fastener structure fastening the seed boot to the base mount member by extending through the base bore and the boot bore. The fastening assembly includes a fastener interface device inserted into at least one of the bores. The interface device comprises a substantially tubular insertion portion inserted into the at least one bore and a flange portion connected to the insertion portion, and extends radially outwardly from the insertion portion.

Abstract: An improved animal self-feeder that has a feed reservoir vertically disposed above a trough and that has an intermediate feeding plate disposed between the reservoir and the trough. The self-feeder includes an outlet for discharging feed downwardly from the reservoir onto the intermediate feed plate from which the animal can feed or can knock the feed into the trough below to feed. The self-feeder further includes an agitation assembly for agitating the feed within the reservoir to enhance its flow through the outlet. The agitation assembly is rotationally mounted within the reservoir such that it is rotatable through a complete circle, or 360.degree.. In a preferred embodiment the present invention further includes a jack screw and crank for changing the elevation of the agitation assembly and feed plate.
