VOLUMETRIC METERING SYSTEM WITH SECTIONAL SHUT-OFF Abstract of the Disclosure A volumetric metering system for a seeding machine is provided with a plurality of movable inserts each insert defining a ledge over which the seed falls to the meter outlet. The inserts are selectively movable between an open position in which seed is allowed to flow over the ledge and a closed position in which the 10 inserts close the product flow to the outlet. By locating the product shut-off after the meter but before product enters the distribution system, there will only be a short delay in stoppage of product flow once the shut-off is closed. CN m |
