10/10/12 PT6030 and PT8030 Pull-Type Planter 401-032M
Great Plains Mfg., Inc.
Fasteners
When working on the planter torque all bolts, screws, and
nuts to the correct values listed in the Torque Values Chart
in “Section 10 Appendix” on page
62. Check latches
and other fasteners on the planter to prevent failures in the
field.
Finger Pickup Meter
Inspect and repair the finger pickup meter by removing the
2 bolts holding the meter to the hopper. Remove the 3
bolts on the meter baffle to gain access to the finger mech-
anism.
Rotate the meter input shaft by hand to check the fingers.
The fingers should be against the carrier plate in the area
shown closed and raised in the area shown open in Figure
7-4.

Inspect the brush for wear. The brush should cover at least
1/2 of the finger pickup tab. Replace every 100 acres of
row operation, see Figure 7-4 for location.
Chaff and debris can build-up in the meter preventing
proper functioning of the fingers. Clean every 50 hours of
operation.
To clean the corn meter:
1. Remove the cotter pin, lock nut, and adjusting nut
from the shaft.
2. Lift the finger assembly off the shaft and clean.
3. Replace worn fingers and springs by lifting the finger
out of the slot. Average life expectancy of these parts
should be 250-300 acres of row operation. When fin-
gers are replaced, the open end of the spring loop
should be toward the inside of the finger housing.
4. Inspect the indentations in the carrier plate for wear.
Replace the carrier plate when wear to the plate be-
comes excessive or the seeding accuracy will be af-
fected.
5. Reassemble the meter in reverse order. Be sure the
fingers are installed correctly so the finger housing is
flush with the carrier plate. If the finger housing is not
flush with the carrier plate, make sure that the projec-
tion on the cam is in the notch on the bearing housing.
The meter will not function properly if the projection is
not in the notch.
6. With the finger assembly against the plate, tighten the
adjusting nut until it is snug. Then turn an additional 1/
3 turn. Turn the meter by hand making certain that the
meter is not over tightened. Proper meter resistance
would be 22-25 in/lbs of torque applied at the meter in-
put shaft.
7. Install the cage nut and the cotter pin.
8. Install the baffle and attach the meter to the hopper.
Note: Check tightness of the adjusting nut on the
meter after the first day and periodically thereafter.
Check the belt on the meter periodically.
Use these steps:
1. Remove the 4 bolts (#1) located on the belt housing,
the bolt holding the belt roller and the belt housing
cover (#2). See Figure 7-5.
