Setting Seed Rate Handle
Refer to Figure 24
There is a seed rate adjustment handle for each drill
section. Position handlesNull4: to the setting indicated
on the seed-rate charts.
To adjust handle, loosen wing nut under handle and slide
handle until indicator lines up with correct setting.
Positioning Seed Cup Doors
Refer to Figure 25
For wheat and other small seeds, move seed cup door
handles to highest position. For soybeans and other
large seeds, lower handles to second position. If
excessive seed cracking occurs, lower handles to third
position. For seed cup clean out, move handles to fourth
position, wide open. Make sure all handles are in the
same position before drilling.
 NOTE: Do not open seed cup door to wide open
position with seed in the box unless complete
cleanout is desired. The door may be difficult to close
off once it is opened.
