ABSTRACT:
A seed planter is provided with a stationary, funnel-shaped bin whose lower-end extension is constructed as a pair of electromagnetically, pneumatically, or mechanically pivoted brackets, defining a duct smaller than the grain when the brackets are closed. Other seeds are blown out of the funnel while one is retained until deposited upon briefly opening the brackets.
