Keep Riders Off Machinery

A rider on machinery is sub­ject to injury such as being
struck by foreign objects or
being thrown off the ma­chine. A rider obstructs the
operator’s view, resulting in
unsafe machine operation.

Keep riders off any machin­ery while in operation. Allow only skilled persons to op­erate machinery.

Great Plains Mfg., Inc.

Important Safety Information

Use Safety Lights and Devices

Slow moving tractors, self-propelled
equipment and towed implements or at-
tachments can create a hazard when
driven on public roads, and are difficult to
see, especially at night.

Flashing warning lights and turn signals
are recommended whenever driving on
public roads. Use the lights and devices
provided with your machine.

Keep safety signs and lights in good condition. Replace
any missing or damaged items.

Transport Machinery Safely

Comply with state and local laws when
transporting machinery.

Maximum transport speed for planter is 20
mph. DO NOT EXCEED. Never travel at a
speed which does not allow adequate con-
trol of steering and stopping.

Braking from transport speed can cause a
towed load to swerve and upset. Reduce
speed if towed load is not equipped with
brakes.

Use the following recommended speed-
weight ratios as a guideline:

● Maximum speed of 20 mph when weight

of towing load is less than or equal to the
weight of your tractor.

● Reduce speed to 10 mph when weight of towed load

is up to double the weight of your tractor.

● Do not tow a load which is more than double the

weight of your tractor.

Use a Safety Chain

A safety chain will help
control drawn machin-
ery should it separate
from the tractor draw-
bar.

Use a chain with the
strength rating equal to
or greater than the gross weight of the towed machin-
ery.

Attach the chain to the tractor drawbar support or other
specified anchor location. Allow only enough slack in
the chain to permit turning.

Do not use safety chain for towing.

Avoid High Pressure Fluids Hazard

Escaping hydraulic oil can have ex-
tremely high pressure which can
penetrate the skin causing serious
injury.

Avoid this hazard by relieving all hy-
draulic pressure before disconnect-
ing any lines. Be sure all connections are tight before
applying pressure.

Protect hands and body from high pressure fluids. Use
a piece of cardboard or wood to detect leaks.

If an injury is caused by escaping hydraulic fluid. SEE A
DOCTOR IMMEDIATELY! The fluid must be surgically
removed within a few hours or gangrene will result

Practice Safe Maintenance

Understand maintenance proce-
dure before doing work. When ser-
vicing machine use proper tools
and equipment. Refer to operator’s
manual.

Keep hands, feet, and clothing
away from power-driven parts. Dis-
engage all power and relieve pres-
sure.

Lower machine to the ground. Stop
tractor engine and remove the key.
Allow machine to cool before ser-
vicing.

Keep the area clean and dry.

Securely support machine compo-
nents that will be raised during service.

Disconnect battery ground cable (-) before servicing or
adjusting electrical systems or before welding on ma-
chine.

Make sure all parts are properly installed and in good
condition. Fix any damage immediately and replace
worn or broken parts. Remove buildup of grease, oil or
debris.

Prior To Operation

1. Practice safety by always thinking before acting.

2. Make sure safety rules are understood before operating ma­chine or tractor.

3. Loose fitting clothing should not be worn as it may catch in
moving parts.

4. Never attempt to operate the implement unless you are in
the driver's seat.

5. Never dismount from a moving tractor.

6. Do not leave the tractor or the implement unattended with
the engine running.

7. Do not stand between the tractor and the implement during
hitching.

During Operation

1. Never allow the planter to be operated by anyone who is un-

familiar with the operation of all functions of the unit. All
operators should read and thoroughly understand the in­structions given in this manual prior to moving the unit.

2. Never permit any persons other than the operator to ride on
the tractor.

3. Regulate your speed to the field conditions, maintaining
complete control at all times.

4. Always lower the implement and shut off the tractor engine
before making any adjustments.

5. Do not grease or oil machine while it is in operation.

6. Always make sure there are no persons near the planter
when the marker assemblies are in operation.

7. Watch for obstructions such as wires, tree limbs etc., when
folding markers.

8. If a hydraulic leak develops, correct it immediately. Escap­ing hydraulic oil can have extremely high pressure. A
stream of high pressure oil may easily penetrate the skin as
with modern needless vaccination equipment - but with the
exception that hydraulic fluid may cause blood poisoning. It
is imperative that the connections are tight and that all lines
and pipes are in good condition. If an injury is caused by the
escaping hydraulic fluid, see a doctor at once!

After Operation

1. Detach and store implements in an area where children nor-

mally do not play. Stabilize implements by using suitable
supports and block wheels.

During Maintenance

1. After repairing or adjusting, make sure all tools and parts

are removed from the implement before attempting to oper­ate it.

2. Never work under a raised planter.

3. Disk edges are sharp! Be careful when working in this area.

4. Use a piece of cardboard or wood to detect leaks of hydrau­lic oil under pressure.

5. Be sure to relieve all hydraulic pressure before disconnec­tion any lines or pipes between the implement and the trac­tor hydraulic system. Keep all guards and shields in place.

Transporting

1. Before transporting make sure the hitch is securely attached
to the draw bar of the tractor and the safety chain is con­nected.

2. Be alert to traffic when crossing or operating near road-

ways. Always maintain complete control of the machine.
Know your state and local laws concerning highway safety
and regulations. Comply with these laws when transporting
machinery.

3. Do not exceed 20 mph when transporting. Transport only

with a farm tractor of sufficient size and horse power. See
Tractor Preparation in “Section 2 Planter Operation”
on page 13.

4. Always make sure flashing safety lights, slow moving vehi-

cle emblem, and reflectors are in place and visible prior to
transporting the machine on public roads, when required.

5. Do not transport at night or during other periods of poor

visibility.

Tire Handling & Repair

1. Tire changing can be dangerous and should be preformed

by trained personnel using the correct tools and equip­ment.

2. Do not re-inflate a tire that has been run flat or seriously

under inflated. Have it checked by qualified personnel.

3. When removing and installing wheels, use wheel handling

equipment adequate for the weight involved.

Agricultural Chemicals

1. Agricultural chemicals can be dangerous. Always select the
correct chemical for the job. Improper usage of fertilizers,
fungicides, herbicides, insecticides, and pesticides could
cause injury to all living things.

2. Always read instructions supplied by the manufactures be-

fore opening chemical containers. Read and follow instruc­tions supplied by the chemical manufacturer carefully
before each use.

3. Apply the same precautions when adjusting, servicing,

cleaning, or storing this implement as you would when put­ting chemicals into it.

4. Inform anyone who may come in contact with chemicals, or

an implement with chemicals, of any potential hazard or
safety precaution that should be observed.

5. Avoid inhaling smoke from any type of chemical fire.

6. Store or dispose of all unused chemicals as specified by the

chemical manufacturer.

Transporting

!

CAUTION!

The planter should never be transported faster than
20 miles per hour!

Before transporting the planter, check and practice the fol­lowing items:

• The planter can be transported with full hoppers of seed.

It is best NOT to because the extra weight increases the
chances for problems on the road. Do not exceed 20

miles per hour.

• Check to see that the gauge tires on the planter have the

proper inflation, see the Tire Inflation Chart in “Section
10 Appendix” on page 62.

• Comply with all Federal, State and Local Safety Laws

when traveling on public roads.

• Remember, the planter is wider than the tractor and ex-

treme care must be taken to allow for safe clearance.

• Make sure the safety chain is properly attached with

enough slack in the chain to permit turning.

Leveling the Planter

IMPORTANT: For proper planter operation, it is important
that the planter frame be fully lowered into the correct
planting position. Achieving this position can be difficult
with some attachment combinations, especially when
planting in hard to penetrate soil conditions. If this situa­tion is encountered, the following action may be warrant­ed.

Reduce attachment down force levels. Avoid using more
attachment down force than is required.

Periodically check the planter to be certain the planting
units are running level.

Lower planter to planting position with the bottom of main
frame tube approximately 20 to 22 in. above level ground.
Refer to Figure 2-2.

When planting, the top of the hopper support panel should
be parallel to the ground.

Position tractor drawbar as required to obtain the proper
planter hitch height.

Rephasing the Hydraulic System

!

WARNING!

Escaping fluid under pressure can have sufficient pressure to
penetrate the skin. Check all hydraulic lines and fittings before
applying pressure. Fluid escaping from a very small hole can be
almost invisible. Use paper or cardboard, not body parts, and
wear heavy gloves to check for suspected leaks. If injured, seek
medical assistance from a doctor that is familiar with this type
of injury. Foreign fluids in the tissue must be surgically removed
within a few hours or gangrene will result.

Refer to Figure 2-3:

The lift system on your Great Plains Pull-Type Planter is a
master/slave system. All cylinders in the system are 2/way
cylinders. Rephasing the system is accomplished each
time the planter is lowered to the planting position. If un
level lifting occurs, lower the planter to the ground and hold
the remote lever momentarily. This time will allow oil to go
from the tractor to the master; bypass to the slave, then re
turn to the tractor.

If following this procedure does not level the planter, refer

“Section 7 Maintenance and Lubrication” on

to
page 45.

Marker Hydraulics

!

DANGER!

Never allow anyone near the planter when cycling the markers.
Excessive travel speed of the markers can be dangerous and/or
damage the marker assembly.The flow controls should be prop
erly adjusted before the marker assembly is first put into use.

The marker hydraulic system is equipped with needle
valves to control how fast each marker operates. The nee
dle valves are built into the sequence valve body. There
are two hex adjustment heads, one for controlling marker
speed up and one for controlling marker speed down. To
adjust the speed of each marker, loosen jam nut, screw
the needle valve clockwise to adjust the marker speed to a
low setting. Fold the marker up and down a few times and
recheck for pinching and kinking of hoses. With the tractor
engine at an operating rpm, adjust the needle valve to limit
the marker to a safe operating speed. Excessive folding
speeds can cause marker damage.

!

WARNING!

Escaping Fluid under pressure can have sufficient force to pen­etrate the skin. Check all hydraulic lines and houses before ap­plying pressure. Fluid escaping from a very small hole can be
almost invisible. Use paper or cardboard, not body parts, to
check for suspected leaks. If injured, seek medical assistance
form a doctor that is familiar with this type of injury. Foreign
fluids in the tissue must be surgically removed within a few
hours or gangrene will result.

General Notes

• If both markers are required down at the same time run

one marker down, momentarily start to raise it, reverse
the hydraulic lever and lower the opposite marker. Hold
ing the lever down then will force both markers down.

-

If the markers are down they can both be raised simul­taneously but they can only be lowered one at a time al­ternating from one side to the other.

• When oil is cold, hydraulics operate slowly. Make sure

-

all adjustments are made with warm oil.

• On a tractor where the oil flow cannot be controlled, the

rate of flow of oil from the tractor may be greater than the
rate at which the marker cylinder can accept it. The trac
tor hydraulic control lever will have to be held until the
cylinder reaches the end of its stroke. This occurs most
often on tractors with an open center hydraulic system.

On tractors with a closed center hydraulic system, the
tractor’ s hydraulic flow control can be set so the tractor’s
detent will function properly.

Marker Transporting

Always transport the marker with it folded in the flat fold
position.

Pump Mounting and Hose Arrangement

The pump should always be mounted even with or lower
than the fertilizer tank and for accurate metering, the
speed should not exceed 125 RPM.

An important consideration for efficient operation of the
pump is the hose arrangement. If fewer than the standard
number of hoses are to be used, that is, using 4 or 5 hoses
on a 6 hose pump or 10 hoses on a 12 hose pump, the re
duction in the number of hoses may be made by:

1. Removing the hoses from near the center of the intake

manifold and capping the intake ports.

2. Running the unneeded hoses back into the solution
tank or tanks with the hoses still connected to the
pump.

!

CAUTION!

Avoid pressure when using the quick fill attachment. The rubber
plugs installed in the manifold may be forced out under pres
sure.

The discharge manifold must be in the forward position
when the pump is in operation. Squeeze Pumps are
shipped with the discharge manifold in the rearward or
non-operating position. To reposition the manifold, loosen
the wing nuts and slide the manifold forward and sideways
or rearward as required and retighten nuts. See
Figure 2-10.

-

Discharge Manifold Forward Position

Shut-off valves provided at various locations should be
closed to shut off flow when the planter sets overnight or
for extended periods of time. It is also important to close
the tank valves whenever service on the pump or hoses is
being performed. To prolong the life of the hoses in the
squeeze pump, the discharge manifold must be reposi
tioned to the rearward position when not in use to prevent
hose distortion. See

Seed Hopper

The row unit is equipped with one 2-bushel translucent
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 ob
jects from entering the hopper and also aids in keeping out
moisture.

Chemical Hopper

The optional chemical hopper comes in 2 versions:

• 1 chemical meter and an 80 lb. capacity translucent

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 for­eign objects. After filling the hopper(s) replace the hop­per(s) lid(s). Operating with the lids attached prevents
objects from entering the hopper and also aids in keeping
out moisture.

Chemical Hopper

Figure 3-5

The application rate is determined by:

1. The size of the opening on the meter housing assem­bly.

2. The travel speed.

The size of the opening is adjustable by turning the knobs
on the rear of the granular hoppers. There are 99 incre
ments which indicate the relative application rate. The de­livery rate will increase from 1 through 99. Setting 00
closes the opening completely. A fluted roller delivers the
granular chemical to the adjustable opening.

The granular chemical flows through a given opening size
at a nearly uniform rate regardless or rotor rpm. Therefore,
SPEED has the greatest impact on application rate and re
sulting chemical concentration in the row.

For example, if planting speed is reduced from 6 to 3 mph,
chemical concentration will nearly double since the deliv
ery rate through the orifice remains nearly the same while
the distance traveled in a given period of time has been cut
in half. Therefore, twice as much chemical is placed on the
ground due to the decrease in ground speed.

Rotor rpm will not change the chemical meter delivery rate
unless the seed population is changed significantly
(i.e. + 25 percent or more from the original setting).

Section 3 Row Unit Operation

Great Plains Mfg., Inc.

The rate charts in “Section 5 Adjusting Planting Rates”
on page 28 are approximate, and are based on a planting
speed of 5 mph. They are to be used only as a guide to de­termine a starting point for the meter dial setting.

Always check your rate of application as outlined in this
section to be sure you are getting the desired rate.

Use the application rate and meter setting recommended
by the chemical manufacturer as a starting point for the
meter dial setting.

If the meter setting is not available from the chemical man­ufacturer, use the charts in “Section 5 Adjusting Plant-
ing Rates” on page 28 as a starting point for the meter
dial setting.

IMPORTANT: Because the available chemical materials
vary widely in consistency and composition, their “flow­ability” is affected by temperature and humidity conditions.
It is important to calibrate each individual meter to the par
ticular chemical being used.

To determine the application rate and starting meter set­ting, proceed as follows:

The chemical manufacturer may recommend the rate of
application for granular chemicals in the following ways:

1. Ounces per 1000 linear row feet.

2. Pounds per acre for a given band width and row spac­ing.

3. Pounds per acre for complete (broadcast) coverage.

When the chemical manufacturer recommends ounces
per 1000 linear row feet or pounds per acre for a given
band width and row spacing, proceed to the chemical
manufacturer’s recommended meter setting or to the
meter setting recommended in the rate charts.

When the chemical manufacturer recommends pounds
per acre for complete (broadcast) coverage only, it is nec
essary to reduce the pounds per acre to apply for your
band width and row spacing. This will give you the same
chemical concentration in the band area as the chemical
manufacturer recommends for complete (broadcast) cov
erage.

Use the following formula to find the pounds per acre for
your band width and row spacing.

NOTE: We recommend you actually measure the
band width applied in your conditions and use this
width in your application rate calculations.

A X B/C = Delivery rate per acre for a given band width
and row spacing.

A - Chemical manufacturers recommended rate in pounds
per acre for complete (broadcast) coverage.

B - Band width in inches.

C - Row spacing in inches.

Example: The chemical manufacturer recommends 20 lb/
acre for complete broadcast coverage. The band width is
14 inches. The row spacing is 30 inches.

20 x 14/30 = 9.3 lb. per acre.

The required delivery rate for 14 inch bands and 30 inch
row spacing would be 9.3 lb/acre. Set meter setting rec
ommended for 9.3 lb/acre broadcast coverage.

Delivery of 9.3 lb/acre of chemical in a 14 inch band will
provide the same chemical concentration on the soil sur

-

face as delivery of 20 lb/acre broadcast coverage.

Proceed to chemical manufacturer’s recommended meter
setting or to the meter setting recommended in the rate
charts in this section which will deliver 9.3 lb/acre.

To check the exact number of lb/acre of chemical that will
be delivered, attach a plastic bag to each chemical diffus
er, lower the planter, and proceed as follows:

Drive 500 feet at planting speed. Weigh the chemical in oz.
that was caught in one bag. Multiply that amount by the
factor shown to determine lb. per acre.

Check the chemical caught in each bag in the same man­ner.

Lb. Per Acre Factor for

Given Row Width

Row Width Factor

-

­Example: Assume you are planting 38 inch rows and you

38 inch 1.7

36 inch 1.8

30 inch 2.2

caught 5.6 ounces in one bag (one row).

5.6 ounces times 1.7 (factor for 38 inch rows) equals 9.5
lb. per acre.

If the desired amount is not obtained for each unit with the
first setting, turn the metering knob and repeat the check
until desired amount is delivered.

NOTE: If a significant difference in rate is observed
between rows, the meter dial mechanism may re­quire recalibration.

-

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.

The aggressiveness and the mark left by the disk may be
changed by two methods:

Refer to Figure 4-1:

1. Disk Angle

To change the angle of cut, loosen the two bolts (1),
rotate the disk assembly and retighten.

2. Direction of Cut

The disk may be mounted to throw dirt either in or out
which will give different marks in different soil condi
tions. To change the direction of cut:

a. Reverse the blade and depth band by remounting

the four lug bolts on the disk hub.

b. Reverse the angle of the assemble by removing

the adjustment bolts (2) and turning the spindle
assembly one half turn. Reinstall and tighten all
bolts.

Marker width adjustments are made by loosening the
marker tube u-bolt #(2) and sliding it in or out to the de
sired width and by tightening the u-bolt.

Dimension (A) is measured from the center line of the
planting unit to the marker disk.

This are approximate dimensions and should be checked
in the field.

For 6-row wide, 36 inch rows, A = 126 inches.

For 6-row wide, 38 inch rows, A = 133 inches.

For 8-row narrow, 30 inch rows, A = 135 inches.

After adjusting marker, tighten u-bolt.

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 4-2:

1. Latch the appropriate hopper into place on the sup­port.

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.

Closing Wheel Offset

The 1x12 wheels can be offset to help prevent trash from
plugging the closing wheels. If the closing wheels are not
offset, the wheels should be located in the front holes of
the press wheel arm.

To offset the wheels, do as follows:

1. Raise planter slightly to remove weight on the closing
wheels.

2. Remove the 3/4” bolt holding the wheel, see
Figure 4-10.

3. Move the wheel to the rear hole and attach with the 3/
4" bolt. Tighten the bolt to the correct torque value list
ed in the Torque Value Chart in “Section 10 Appen-

dix” on page 62.

Seed Lok

The seed lok option provides additional seed to soil con­tact. The seed lok is spring loaded and does not require
adjusting. In some wet and sticky conditions the wheel
may accumulate soil and may require removal of the seed
lok until conditions improve.

The seed lok is attached to the shank with a 1/2” clevis pin,

Figure 4-14. To remove the seed lok, remove the cle-

see
vis pin and pull down on the seed lok mount.

Reattach in the reverse order.

Section 5 Adjusting Planting Rates

Section 5 Adjusting Planting Rates

This section discusses the adjustments and settings for
seeding and chemical rates.

Planting Rates

Please read the following sections. Complete understand­ing of this process will help to prevent problems.

Transmission Adjustment

Planting population changes are accomplished by setting
the sprocket transmission. By changing the combination
of sprockets the desired planting populations can be
achieved.

To change the sprocket combination refer to “Planting
Rates for Finger Pickup Corn Meters” on page 30:

1. Select the sprocket combination for your planting pop­ulation.

2. Remove the cover from the transmission by loosening
the knob on the cover.

3. Release the spring tensioner on the idler, see Figure
5-1.

8. Turn the idler plate counter-clockwise (ccw) to take up
the slack. Hook the spring onto the idler plate Rotate
the tensioner over center. If the chain is too loose,
hook the spring onto the next notch in the plate.

9. Replace the transmission cover and hand tighten the
knob.

Checking Planting Population

After setting the transmission, ALWAYS check the planting
population in the field.

Follow these steps to check the planting population:

1. Tie up 1 or more closing disks and wheels with a chain
or heavy wire to the hopper support. Releasing the
spring pressure on the disks and wheels will make this
easier. Adjust the planting depth to a shallow setting. It
may be necessary to tie up the seed lok wheels so that
the seeds are easier to find.

2. Plant at a normal speed for a short distance.

3. Measure 1/1000 of an acre. For 30" row planter
1/1000 of an acre is 17' 6".

4. Multiply the number of seeds counted by 1000. This
gives you total population.

Example: (for one row)

• 30” row spacing

• 17’ 6” of seed trench measured off

• 24 seeds counted in measured distance

Spring Tensioner on Transmission

Figure 5-1

4. Remove the chain and sprockets.

5. Exchange the sprockets with the desired sprockets,
selected in step 1, on the storage bracket.

Note: When not in use, keep all extra sprockets on
the storage bracket.

6. Place the sprockets on the drive/driven shafts.

7. Loop the chain over the sprockets and between the 2
idlers.

24 Seeds Counted X 1000 =

24,000 Plant Population Per Acre

If the planting population is significantly different than the
desired planting population, make the following checks:

• Check the sprocket combination in the transmission, re-

fer to the “Planting Rates for Finger Pickup Corn
Meters” on page 30.

• Check the tire pressure in the gauge wheels in “Section

10 Appendix” on page 62.

• Check for meter malfunction, see Finger Pickup Corn

Meter in

Planting Recommendations

To get the best planting results, follow these recommenda­tions:

“Section 6 Troubleshooting” on page 42.

• Plant at 5 mph

• Add 1 teaspoon of graphite to each seed hopper.

• Maintain tire pressure in the gauge tires.

• Replace worn meter parts.

Section 5 Adjusting Planting Rates

Great Plains Mfg., Inc.

Drive Wheel Slippage

Another item that may cause the actual rates of seed or
fertilizer to differ from the delivery rates shown in the oper
ator’s manual is the amount of drive wheel slippage.

While a certain amount of wheel slippage is normal, ex­cessive drive wheel slippage may cause undesirable
changes in the actual rates.

Excessive drive wheel slippage may be caused by binding
or poorly lubricated parts, misaligned bearings or caked
material in the pesticide or fertilizer hoppers.

In addition, down pressure springs, coulters, tine tooth at­tachments, or any other attachment that removes frame
weight from the drive wheels, may contribute to drive
wheel slippage and lower than expected rates.

If in-field checks indicate that the planter is planting at a
rate significantly different than the seed transmission rate
chart indicates, investigate the following in the order listed:

• Ensure that ALL transmission sprockets are set accord-

ing to the rate chart.

• Excessive unit bounce can cause low population and re-

duced spacing control. Reduce excessive unit bounce
by increasing unit down force, or drive slower.

• Ensure that the planter drive wheel slippage is close to

normal. Variations in drive wheel slippage can be
caused by crop residue, tire inflation pressure, soil con
ditions and unit down force.

9. If required, adjust the meter setting and repeat steps 4
through 7 until the desired rate is reached.

Adjusting Granular Chemical Rates

The optional chemical applicators are adjusted by
varying the opening on the chemical meter housing. The
field check is very important because temperature, humid
ity, speed, ground conditions, flowability of chemicals, and
obstructions affect the application rate.

!

WARNING!

Agricultural chemicals can be dangerous if not selected and
handled with care. Always read and follow directions supplied
by the chemical manufacturer.

To adjust the chemical rate do as follows:

1. Select a setting from the “Granular Chemical Rate
Charts” on page 33, as a starting point.

2. Slide the handle on the meter to the setting,
see Figure 5-2.

3. If the meter has a knob, turn until the display shows
the appropriate number, see

4. Fill the hoppers with chemical.

5. Attach a plastic bag to each chemical
diffuser.

6. Drive 1320’ at a normal planting speed.

7. Weigh the contents of the bag in ounces.

8. Multiply ounces by 0.83 to determine the pounds
per acre.

Chemical Meter with Knob

Figure 5-3

Liquid Fertilizer Attachment

!

WARNING!

Agricultural chemicals can be dangerous if not selected and
handled with care. Always read and follow directions supplied
by the chemical manufacturer.

On machines equipped with the squeeze pump option, the
rate of liquid fertilizer application is determined by the
combination of sprockets on the squeeze pump driven and
drive shafts. When changing sprocket combinations,
make sure sprockets are in alignment, sprocket retaining
collars are tight and chain tension is sufficiently restored.

The “Liquid Fertilizer Rates” on page 40 provides an
approximate application rate only. Actual delivery will vary
with temperature and the particular fertilizer being used.

IMPORTANT: Certain analysis of fertilizer if placed too
close to the seed may cause germination of seedling
damage especially if used in amounts in excess of fertiliz
er manufacturer’s recommendations. Check with your fer­tilizer dealer or manufacturer for the correct amount and
placement.

Install Cylinder Stops

!

CAUTION!

Always install cylinder stops when working around or near
planter.

Refer to Figure 7-1:

Raise planter to transport position with tractor remote cyl­inder operating lever. Pivot cylinder stop into position on
wheel module cylinder rods. Lower to stop.

NOTE: Cylinder stops are provided for added safety
when performing normal maintenance and adjust­ments with the planter raised.

Infrequent or improper lubrication causes “binding” of
moving parts within the planter. This “binding” will cause
the cotter shear pins to shear, thus preventing breakage of
planter parts.

If either cotter pin shears, turn the drill shaft by hand to lo­cate where the binding is occurring. When the drill shaft
can be turned freely by hand, replace the cotter pin.

NOTE: Replace the cotter shear pins only with cotter
shear pins of the same size. Do not replace with oth­er type pins.

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 af­fected.

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.

Finger Raised/Location of Brush

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

Storage

To extend the life of your planter follow the recommenda­tions for removing the planter from storage and storing the
planter during the off season.

Beginning of the Season Service

Before using the planter after it has been stored, inspect
the seed hoppers for cleanliness to be certain the seed will
flow from hoppers freely.

Thoroughly inspect the planter unit for loose parts and ad­just as necessary. Check all bolts and replace worn parts
to prevent failure in the field.

Clean any dirt or grease that may have accumulated on
moving parts, and chains before operating the planter.
This will prevent abrasive action that could cause exces­sive wear.

When roller chains remain unused for several days, mois­ture in the air will accumulate on the chain, causing the
chain to rust. This can, and will, become serious enough in
time to cause the chain joints to become stiff, restricting
their normal free movement. While very difficult to detect,
this stiffness can encourage the chains to operate abnor­mally and disturb the smooth rotation of important meter
components, causing deterioration in performance.

If the planter is not used for several days, or if oil has been
removed from chains, etc. while cleaning the planter thor­oughly lubricate chains with multipurpose spray lube.

Remove the finger pickup meters from the hoppers. Dis­assemble the meters and inspect them for wear. Make
any repairs required at this time. Blow excessive debris
from the meter. Wash the meters with mild soap and wa
ter. Dry the meters and spray a light coat of rust inhibitor
on the meters. Reassemble and store in a dry place.

Thoroughly flush liquid herbicide system with clean water.
Disconnect from tractor and completely drain all lines and
components to prevent damage from freezing.

Store the planter in a clean, dry place with all tires out of
the sun. A sheltering structure is best for overall protec­tion, but a high quality tarp would suffice.

-

IMPORTANT: Do not use chain lube or any other heavy
petroleum base lubricant that may cause a buildup of dust
or dirt in the sprocket or gear teeth.

Turn the meter drive shaft by hand to be sure the drive
shaft and seed meter are free to turn. Rotate forward only,
as assemblies are not designed to rotate in reverse.

Be certain all adjustments are made for the planting con­ditions to be encountered.

Service at the End of the Season

When planting is complete clean the seed and chemical
hoppers. Remove all dirt, debris, chemicals, and fertilizer
from the planter that may hold moisture and cause
corrosion.

Use spray paint to cover scratches, chips, and worn areas
on the planter to protect the metal.

Lubricate the planter as outlined in Lubrication. Pay care­ful attention to the lubrication of the chains to help prevent
rusting.

Inspect the planter for worn or damaged parts. Make re­pairs and service during the off season to reduce down
time in the field.

Place the 1 X 12 closing wheel handle in the middle slot to
relieve the tension on the closing wheels. Move opener
adjustment bar on heavy and medium down pressure
spring packages to hole A.
