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. A transmission arrangement provides for adjustment of the metering rate of the rotors so that a desired metering rate may be obtained.
