Abstract: The air seeder has a series of rotors which deliver a plurality of metered seed streams from a hopper and into a corresponding plurality of transfer condutis. The downstream ends of the transfer conduits are grouped together by a plate for quick and easy movement as a unit. The plate may be either coupled with a panel for delivery of the seed streams to delivery conduits for distribution of the seeds to the ground behind furrow openers or coupled with a sample collector inlet for collection of the seed streams therein. During normal planting operation the rotors are ground driven so as to meter an amount of seeds corresponding to the acreage traversed by the implement. During sampling, the rotors are manually operated so as to deliver a sample corresponding to a certain sample acreage. The sample is collected in the sample collector and the metered seed rate is determined by dividing the sample weight by the sample acreage.

Abstract: A seeding boot for use with a cultivator shank and utilized for delivering particulate material such as seed, fertilizer, chemicals or the like to soil prepared by a soil working tool comprises a soil deflector which defines a surface for deflecting soil over the seeds deposited on the prepared soil, and thereafter allows the soil to cover the seeds, and a diffusing member matingly engageable with the soil deflecting member for diffusing the seeds or the like into substantially parallel rows and includes a downstream portion which abuts against the inner surface of the soil deflecting member and an upper surface portion separated from the lower surface portion by a predetermined dimension so that together with the soil deflecting member will define an interior cavity through which the particulate matter will be directed, a portion of the upper surface being biased so as to receive various sizes of seed conduits and to increase the versatility of use of the seeding boot.
