Cleaning Out Meters
Procedures vary for
10HD/25P meters (page 96) and
20P meters (this page).
Cleaning Out 20P Meters
Clean-out is indicated for:
• changing seed wheels,
• seed recovery, and;
• field meter maintenance.
On 20P 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 127
2.
Slide the retaining ring up and remove the seed
hose .
3. Remove the clean-out door retaining pin clip .
Refer to Figure 128 and Figure 129
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.
Note: How freely seed flows out the clean-out depends
on the seed size, shape and treatments. It is com-
monly necessary to gently tap or shake the meter
to ensure complete flow.
6. When seed stops flowing, uncouple the meter drive
(page 76), spin the seed wheel in reverse (counter-
clockwise) to free any trapped seed.
7. Remove the seed meter wheel for thorough cleaning.
See “20P Meter Wheel Replacement” on page 80
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.
