the ground and manipulate until the holes
align for the desired pinned position.
Once the selected holes are pinned, the
Multi-drill should be operated for a few feet
in the ground to check the frame for level
operation as illustrated in figure 10,

4. Check Seed Depth and Adjust.
After leveling the frame, use a scale to
determine how deep the cuts in the ground
are from the coulter discs. If they need to be
lifted or lowered, select different hole to pin
and repeat leveling process until desired
coulter disc depth is reached.
Once the frame is level and the desired
depth of cut is obtained, a short pass can be
made operating the seeder at the desired
speed (typically the seeder is calibrated at
this point – see next section for instructions).
This allows the operator to check the seed
depth.
After checking the depth of the seed in the
ground, adjustments can be made by
adjusting the pressure on the Press Wheel
(Figure 11). The seed can be slightly
lowered or lifted rotating the Top Link on
the attached Row Unit. Shorten the Top
Link to lower the seed deeper and lengthen
the Top Link to raise the seed closer to the
surface. The Scraper Gauge is used as a
point of reference for this final adjustment.
Simply repeat this step until the proper seed
depth is obtained.
Seeder Calibration
Before operating the seeder, calibration has
to be done in order to take all variables into
account and maximize efficiency of the
seeder. The following steps must be done to
calibrate the seeder:
1.
Determine ground speed.
2.
Select seed rate.
3.
Set seed plates and electric motor
setting
(use Figure 12 as starting point).
4.
Use calibration chart to find target
seed weight (Figure 14).
5.
Position calibration trough to catch
seed and only put enough seed in
hopper to catch.
6.
Operate seeder in air for 1 minute.
7.
Compare weight of seed caught to the
target weight in step 4.
8.
Manipulate seed plates or electric
motor speed to reach target weight.
9.
Repeat steps 5 thru 8 until target
weight is achieved.
10.
Check for consistent seed metering.
