Section 3 Row Unit Operation
8-Row 36", 38", 40" & 10-Row 30" 3-Point Wide Row Planter 401-020M
Seed Hopper
The row unit is equipped with one 2-bushel seed hopper.
Before filling the seed hopper, clear it of foreign objects.
After filling the hopper with clean seeds always replace
the hopper lid. Operating with the lids attached prevents
objects from entering the hopper and also aids in keep-
ing out moisture.
Empty the contents of the hopper periodically to avoid
the collection of dirt and other materials. To remove the
hopper, disengage the meter drive clutch and the hop-
per latch, see arrows Figure 3-4.
Chemical Hopper
The optional chemical hopper comes in 2 versions:
•
1 chemical meter and an 80 lb. capacity hopper
•
2 chemical meters and 1 divider that separates the 80
lb. hopper into 2 compartments - approximately 40 lbs.
each.
Before filling the chemical hopper(s) clear it/them of for-
eign objects. After filling the hopper(s) replace the
hopper(s) lid(s). Operating with the lids attached pre-
vents objects from entering the hopper and also aids in
keeping out moisture
Empty the contents of the hopper(s) periodically to avoid
the collection of dirt and other materials. To remove the
hopper(s), disengage the meter drive clutch and the 2
latch pins at the front of the hopper, see Figure 3-5.

Meter Drive Adjustments
The alignment between the meter clutch and the input
shaft is important. If there is misalignment the meter will
not function properly. Excessive wear and damage can
also occur to the meter housings. When replacing the
meter the vertical and horizontal alignment should be
checked.
Check for Vertical Alignment (Refer to Figure 3-6):
1. Latch the appropriate hopper into place on the sup-
port.
2. The roll pin in the end of meter input shaft should be
centered (equal distances of the roll pin should pro-
trude from both sides of the shaft).
3. Rotate the input shaft so that the roll pin is vertical.
4. Rotate the drive coupler so that the slots are vertical.
5. Release the clutch to engage the drive coupler with
the input shaft.
