Setting Seed-Rate Gauge
Refer to Figure 3
Important! Read gauge left-hand side of plate.
Position seed-rate gauge to setting indicated on
seed-rate charts.
Use the hand crank to rotate the screw located on
the right-hand side of the drill. Rotate the screw one
way or the other until the gauge is at the desired
setting.
Positioning Seed-Cup Doors
Refer to Figure 4
For wheat and other small seeds, move seed-cup
door handles to the highest position. For soybeans
and other large seeds, lower handles to second po-
sition. If excessive seed cracking occurs, lower
handles to third position. For seed-cup clean out,
move handles to the fourth, wide-open position.
Make sure all handles are in the same position be-
fore drilling.
Checking Seeding Rate
!
WARNING
You may be severly injured or killed by being crushed by
the falling implement. Always haave transport locks in
place and frame sufficiently blocked up when working on
the implement.
1. Place a sufficient amount of seed to be calibrat-
ed in the hopper to cover the metering system.
Refer to Figure 5
2. To calibrate, use the crank handle (1) as a key
to push calibration shaft index collar in and ro-
tate to the right.
NOTE: Decals located next to calibration shaft in-
dex collars indicate proper rotation for calibration
and field operation.
Important! This mechanism controls the direc-
tion of seed flow. By rotating the calibration shaft
index collar to the right using the crank handle
(1), the opener hose is blocked off and seed will
collect in the metering tray for calibration.
3. Remove calibration try (2) from storage posi-
tion. Make sure the calibration tray (2) is in the
upright position, locked in place, and clear of
any debris.
