Cleaning Out Meters
Procedures vary for
10HD/25P meters (page 139) and
20P meters (this page).
Cleaning Out 10 and 20 Series Meters
Clean-out is indicated for:
•
changing seed wheels,
•
seed recovery, and;
•
field meter maintenance.
On 20 Series Singulator Plus meters, the clean-out door
enables seed to bypass the seed wheel and exit via the
normal seed tube between the opener discs.
1. Place a tarp, bucket or pan under meter to catch any
seed during clean-out.
Refer to Figure 183
2. Slide the retaining ring up and remove the seed
hose .
3. Remove the clean-out door retaining pin clip .
Refer to Figure 184 and Figure 185
4. Remove the retaining pin . The door may swing
open by itself at this point.
5. Pull the clean-out door handle back until the lower
end of the door rests on the stop bolt.
 How freely seed flows out the clean-out depends on
the seed size, shape and treatments. It is commonly
necessary to gently tap or shake the meter to ensure
complete flow.
6. When seed stops flowing, uncouple the meter drive
(page 80), spin the seed wheel in reverse
(counterclockwise) to free any trapped seed.
7. Remove the seed meter wheel for thorough
cleaning. See “ 10 and 20 Series Meter Wheel
Replacement ” on page 89 for more information.
8. Use a brush or vacuum to remove any residual seed
in the meter cavity. Shake the clean-out door to
ensure it is clear of seed.
