Abstract
A fluent material dispenser, preferably for use in conjunction with a planter, is provided with a precision metering device having buckets which pick up material and dump it into a collector. The collector preferably has discrete axially spaced openings which communicate with separate discharge tubes to deposit material in remote locations. The axially elongated buckets are mounted on a rotor and dump at a substantially uniform rate per degree of rotor rotation, preferably having a radially inner flat wall and an arcuate radially outer wall disposed at a uniform radius about the leading edge of the inner wall. Preferably, the rotor is enclosed in a pressurized housing and air pressure is utilized to deliver the material through the discharge tubes, the air supply and rotor drive being operatively connected with sources as available on the associated planter.
