Seed Disc
Use the proper seed disc for different seeds. Check your
type of seed, and use the
Seed Disc Recommendations
chart to determine the correct disc for your crop.
It is important to use seed discs that are clean and in good
condition. Customized seed discs are not shown, but are
available upon special request. It is not recommended to
drill out seed discs. Any slight burrs or imperfections in
drilling will alter the metering. Do not clean plugged holes
with sharp metal objects. The precision of the seed discs
must be maintained to have proper metering.
The brass agitator is secured to the seed disc with 6
special screws.
If/when seed discs are removed from the metering box to
clean them or to use a different disc, use a permanent
marker to identify which seed disc came from which
metering box. Put seed discs back into their corresponding
metering box. This assures wear patterns on the disc and
gasket match to keep a proper vacuum seal.
