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 machinery should
it separate from the tractor drawbar.

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

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 safe-
ty chain for tow-
ing.

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.

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

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

Description of Unit

The 6- and 8-row, pull-type planter is a towed seeding im­plement. The frame consists of 7-by-7-inch tubing. Plant­ing rates are adjustable by changing sprockets on the
planter transmission or contact drive. Row units are
mounted on the frame. Seed hoppers are standard on the
row units; chemical hoppers and granular-chemical appli
cators are available. Springs on each row unit provide
down pressure needed for the double-disk openers to
make a seed trench. Finger-pickup meters singulate and
dispense seed from the hopper and deliver it to the trench.
Seeding depth is controlled by side gauge wheels on the
openers. Closing wheels or disks close the trench. With an
optional 5-by-7-inch fertilizer bar, the planter can be outfit
ted with dry or liquid fertilizer application and tillage attach­ments.

Intended Usage

Use this implement for seeding row crops in large fields.
Tow the implement behind an agricultural tractor at plant
ing speed of 5 mph and at transport speeds of less than 20
mph. The unit is designed for conventionally tilled fields
but can be used in no- or minimum-till conditions if outfit
ted with optional tillage attachments.

Liquid Fertilizer Option

The pump should always be mounted even with or lower
than the fertilizer tank.

Hose arrangement is important for efficient pump opera­tion. If you will be using fewer hoses than there are on the
pump, remove pump hoses from near the center of the in
take manifold (1) and cap the intake ports (2).

Basic Planting Operation

For the best planting results:

• plant at 5 mph,

• maintain tire pressure in the gauge tires and

• replace worn meter parts.

Rephasing the Hydraulic System

The hydraulic lift system on your Great Plains pull-type
planter is a master-and-slave system. All cylinders in the
system are two way. Each time the planter is lowered into
planting position, the system is rephased.

If unlevel lifting occurs, lower the planter to the ground and
hold the remote lever momentarily.

If following this procedure does not level planter lifting, re­fer to “Section 5 Maintenance and Lubrication” on
page 35.

Seed Meter and Hopper Operation

This planter is equipped with a 12-finger mechanical corn
meter.

To disengage the seed-meter or chemical-hopper clutch,
pull the knob and rotate 90 degrees clockwise or counter­clockwise until the roll pin aligns with the notch in the end
of the drive hub. Release knob. See

To engage, pull and rotate the knob until the shaft aligns
with the drive hub, then release.

WARNING!

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

For accurate metering, keep pump speed below 125 rpm.

To operate the pump, the discharge manifold must be in
the forward position as shown in
shipped in the rearward position.

Squeeze Pump Hose Alignment

Refer to Figure 2-6.

If end hoses (A and B) should run off the back, re-align
hoses as follows:

1. On hose A, loosen hose clamps on intake manifold
and twist hose counter-clockwise 1/4 turn.

2. On hose B, loosen hose clamp on intake manifold and
twist hose clockwise 1/4 turn.

3. Retighten hose clamp.

Transporting

!

CAUTION!

Never transport the planter 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 in
creases the chances for problems on the road.

• Check that the gauge-wheel tires are properly inflated
as listed on the Tire Inflation Chart,
page 52.

• Comply with all federal, state and local safety laws
when traveling on public roads.

• Remember, the planter is wider than the tractor and
extreme care must be taken to allow for safe clear
ance.

• Make sure the safety chain is properly attached with
enough slack in the chain to permit turning.

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

CAUTION!

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

Marker Operation

Markers can be raised simultaneously but can only be low­ered one at a time. 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. Holding the lever down then will force both mark
ers down.

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 tractor
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.

Transmission Adjustment

To change planting population, change the sprocket com­bination on the transmission.

1. Refer to “Planting Rates for Finger Pickup Corn

Meters” on page 16 or “Planting Rates for Brush
Meters” on page 17 for the proper sprocket combina-

tion for your desired planting population.

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

3. Loosen the carriage bolt and flange nut on the idler
plate. Rotate the idler plate to move the idlers out of
the chain.

4. Remove the chain. Remove sprockets currently on
transmission shafts.

5. Find the correct sprockets on the storage brackets
and place on the transmission shafts.

NOTE: When not in use, store all extra sprockets on the
storage bracket.

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

7. Re-route chain over idlers and sprockets.

8. Turn the idler plate counter-clockwise to take up chain
slack. Chain should have a maximum of 1/4-inch
slack.

9. Retighten the carriage bolt and flange nut to secure
idler plate.

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

2-to-1 Drive Reduction

The 15/28 tooth drive sprocket located on the inner side of
the contact drive wheel assembly will give you a 2-to-1
drive reduction and reduce planting rates by about one­half.

NOTE: After each sprocket combination adjustment, make
a field check to be sure you are planting at the desired
rate.

Great Plains Mfg., Inc.

2-to-1 Drive Reduction

Checking Planting Population

After setting the transmission or contact-drive reduction,
always field check the planting population as follows.

1. Release spring pressure on opener disks and wheels.

2. Tie up closing disks and wheels to hopper support us­ing a chain or heavy wire. Pin up optional Seed-Lok
wheels

3. Adjust the planting depth to a shallow setting.

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

5. For 30-inch rows, measure 17 feet 6 inches (one-thou­sandth of an acre.)

6. Count the number of seeds in one row over the mea­sured distance.

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

Example

• 30-inch row spacing

• Measure 17 feet 6 inches

• 24 seeds over measured distance in one row

24 X1000 = 24,000 plant population per acre

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

• Double check the sprocket combination in the trans­mission. Refer to the “Planting Rates for Finger
Pickup Corn Meters” on page 16.

• Check air pressure in the gauge-wheel tires. Refer to
Tire Inflation Chart,

• Check for meter malfunction or excessive contact­drive-wheel slippage. Refer to

shooting” on page 32.

Section 3 Adjustments

Granular Chemical Rates

The application rate is determined by:

• the size of the opening on the meter and

• travel speed.

The size of the opening is adjustable, but ground speed
has the greatest impact on the application rate. For exam
ple, if speed is reduced from 6 to 3 mph, chemical concen­tration will nearly double.

Application rates will also vary with the consistency and
composition of the chemicals, air temperature, humidity
and ground speed. Because of the wide variability in ap
plication rates, you must field check the actual rate of ap­plication for each meter.

!

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:

1. Select a meter setting as a starting point.

• If the chemical manufacturer recommends ounces per
1000 linear row feet or pounds-per-acre for a given
band width and row spacing, use the recommended
meter setting as a starting point.

• If the chemical manufacturer recommends pounds
per acre for complete (broadcast) coverage, you must
calculate the pounds per acre for your band width and
row area. Refer to Conversion from Broadcast to Row
Coverage,

• If the meter setting is not available from the chemical
manufacturer, use
Charts” on page 21. The charts are approximate and
are based on a ground speed of 5 mph. Use these
charts as a starting point for setting the meter.

2. Turn meter knob until the display shows the correct
number. See

3. Fill the hoppers with chemical.

4. Attach a plastic bag to each chemical
diffuser.

5. Drive 500 feet at a normal planting speed.

6. Weigh the contents of the bag in ounces.

7. Multiply weight by 2.2 to determine the pounds
per acre.

8. If necessary, adjust the meter setting and repeat
steps.

IMPORTANT: If a significant difference in rate is ob­served between rows, the meter may require recali­bration. Refer to Recalibrating Chemical Meter, page

20.

Conversion from Broadcast to Row Coverage

If the chemical manufacturer recommends pounds per
acre for complete (broadcast) coverage, you must reduce
the pounds per acre rate to match for your band width and
row area. Use the following formula to find the pounds per
acre for your band width and row spacing.

A X B/C = Pounds per Acre Application Rate

Where:

A = Recommended rate in pounds per acre for complete

(broadcast) coverage

B = Band width in inches

C = Row spacing in inches

NOTE: Measure the actual band width applied in your con­ditions and use this width in your calculations.

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

20 x 14/30 = 9.3 pounds per acre

Set meter to setting recommended for 9.3 pounds per
acre.

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 chart on this page provides approximate application
rates. Actual rates will vary with temperature and the par
ticular fertilizer being used.

NOTE: If placed too close to the seed, certain analysis of
fertilizer may cause germination or seedling damage es
pecially if used in amounts in excess of fertilizer manufac­turer’s recommendations. Check with your fertilizer dealer
or manufacturer for the correct amount and placement.

Dry Fertilizer Attachment

IMPORTANT: Fertilizer application rates can vary
from the weights in the charts. Make field checks to
assure you are applying fertilizer at the desired rate.

Use the following instructions to check the exact number
of pounds your fertilizer attachment will actually deliver on
a 30-inch row spacing.

1. Remove a hose from one of the fertilizer hoppers and
attach a container under the opening.

2. Engage the fertilizer attachment and drive forward for
174 feet.

-

3. Weigh the amount of fertilizer caught in the container
and multiply that amount by 100. The result will be the
pounds of fertilizer delivered per acre when planting in
30-inch rows.

To assure proper application check the gauge tires and
contact drive tire for proper inflation, see Tire Inflation
Chart in

“Appendix” on page 52.

IMPORTANT: Before applying fertilizer make sure
that augers are rotating correctly and are positioned
for your desired rate setting. See Figure 3-6 and Fig­ure 3-7.

Marker Adjustments

Folding Speed

!

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.

!

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.

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.

Excessive folding speeds can cause marker damage.
With the tractor engine at an operating rpm, loosen jam
nut and adjust the needle valve to limit the marker to a safe
operating speed. Make sure all adjustments are made
with warm oil. Fold the marker up and down a few times
and recheck for pinching and kinking of hoses.

Disk Adjustments

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

Refer to Figure 3-18.

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. Re-install and tighten all
bolts.

Marker Width

Refer to Figure 3-19.

To adjust marker width, loosen the marker tube u-bolt (1)
and slide it in or out to the desired width. After adjusting,
retighten the u-bolt.

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

mension.

For 6-row, 30 inch rows, A = 180 inches.

For 8-row, 30 inch rows, A = 240 inches.

Meter Drive Adjustments

The alignment between the meter clutch and the input
shaft on both the seed and chemical hoppers is important.
If there is misalignment, the meters will not function prop
erly. Excessive wear and damage can also occur to the
meter housings. When replacing the meters, check the
vertical and horizontal alignment.

Check Vertical Alignment

­Refer to Figure 3-21.

1. Latch the hopper into place on the support.

2. Check that the roll pin (1) in the end of the input shaft

is centered so equal amounts of the roll pin protrude
from both sides of the shaft.

3. Rotate the input shaft so the roll pin is vertical.

4. Rotate the drive coupler (2) so the slots are vertical.

5. Release the clutch to engage the drive coupler with

the input shaft.

Install Cylinder Stops

!

CAUTION!

Always install cylinder stops when working around or near
planter.

Install cylinder stops whenever the planter is raised for
maintenance. To install the stops, refer to
Raise planter to transport position with tractor remote cyl­inder operating lever. Pivot cylinder stop into position on
wheel module cylinder rods. Lower to stop. Install bent pin
and secure with cotter pin.

Figure 5-1.

When the drill shaft can be turned freely by hand, replace
the cotter pin.

IMPORTANT: Only replace the cotter pins with cotter
pins of the same size. Do not replace with other type
pins.

16889

Figure 5-1

Cylinder Stop

Before lowering the planter, remove bent pin, pivot cylin­der stop off of cylinder, and re-install bent pin.

Replacing Shear Pins

Refer to Figure 5-2.

The cotter pins (1) that connect the transmission-input and

-output shafts to the transmission will shear when an ex
cessive load is put on the shafts.

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

Check for binding by turning the drive shaft with all seed
hoppers installed and seed meters engaged. If the drive
shaft is hard to turn, disengage one seed-meter clutch at a
time to find the problem clutch.

Improper shaft alignment can also cause pins to shear.
Refer to Shaft Alignment, this page, to check shaft align
ment.

Section 5 Maintenance and Lubrication

Great Plains Mfg., Inc.

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

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 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
one-third turn. Turn the meter by hand making certain
that the meter is not over tightened. Proper meter re
sistance would be 22 to 25 inch-pounds of torque ap­plied at the meter input shaft.

7. Install the cage nut and the cotter pin.

8. Install the baffle and attach the meter to the hopper.

Check the belt on the meter periodically. Use these steps:

1. Remove the four bolts (1) located on the belt housing,
the bolt holding the belt roller and the belt housing
cover (2). See

Figure 5-8.

Refer to Figure 5-10.

1. With the unit raised, check the blade scraper (1) for
wear. Replace the scraper if it is 1/2 inches wide or
narrower. To replace, remove a side gauge wheel and
disk blade. Drive out the roll pin (2) and install a new
scraper.

2. Check the disk blades (3) for wear. To maintain proper
planting depth, replace if worn to a diameter of 14 1/2
inches or less.

3. When re-installing disk blades, put three shims be­tween the bearing and cast-iron shank on one blade.
Tighten bolt. On the opposite side, re-install blade with
two (4) shims between the bearing and cast-iron
shank. Tighten bolt.

4. Check that the outside disk scrapers (5) are formed to
the disk blades to help remove any mud. Bend and
twist the scrapers to fit the blades as necessary.
Check outside scrapers for proper adjustment and
wear every 200 acres. Replace outside scrapers as
necessary.

7. Disassemble the side-gauge-wheel arm (2) from the
row unit. Check the arm and bushing (3) for build up of
grease and dirt in the grease groove. Clean as need
ed. Re-install as follows.

a. Place the bushing (3) on stem sticking out of row

unit (4).

b. Place at least three shim washers over the bush-

ing.

c. Slide the gauge wheel arm on the bushing, push-

ing it up to the shims.

d. Place shim washers on the bushing until even with

the end of the bushing.

e. Secure side gauge wheel to arm with a 1/2-inch

bolt, lock washer and flat washer. Tighten to 76
foot-pounds.

5. Check the contact point between the two disk blades.
Place a piece of paper in the top gap between the
disks blades. Bring the paper down until it stops. In the
lower gap place another piece of paper. Bring up until
it stops. Measure the distance between the two pieces
of paper. The distance must be between 1/2 and
1 3/4 inches. Add or remove shims as needed to get
the correct contact point.

Refer to Figure 5-11.

6. Check for the correct number of shims between the
side gauge wheel (1) and the wheel arm (2). There
must be at least one shim between the wheel bearing
and arm. When installed, the wheel should turn freely
and not hit the arm at the curve. Do not add any more
shims than necessary.

16847

Figure 5-11

Reverser Drive

f. Check the distance between the side gauge

wheel and the disk blade at the bottom of the
wheel and blade. The distance between the wheel
and blade must be no greater than 1/8 inch. Place
the T- handle in the lowest hole possible, then lift
the wheel and arm. When let go, the wheel should
fall freely. If the wheel is not close enough to the
blade or the wheel does not fall freely, reposition
shims until corrected.

Chain Tension

As the chains wear and stretch, you may need to remove
links for proper chain length and tension. Check and re
place bushings on idlers. For the correct operation of the
planter check all chain routings. Refer to

Chemical Hoppers

!

CAUTION!

Agricultural chemicals can be dangerous. Follow the instruc­tions of the chemical manufacturer when cleaning hoppers and
handling insecticides or herbicides.

NOTE: Under certain humidity or moisture conditions, ma­terial may tend to cake. When this happens, thoroughly
clean hoppers at the end of each day’s use.

To remove hoppers, proceed as follows:

8. Disengage meter clutch.

9. Release over-center latch.

10. Slide hopper forward and lift hopper off support.

11. Clean thoroughly.

To clean tanks:

1. Remove lids from tanks.

2. Turn valve to elbow.

3. After cleaning tanks, close shutoff valve, replace cap
on metering pump and replace lids on tanks.

Squeeze Pumps

During periods when the pump is not being used, these
important steps are recommended to prevent hose defor
mation and prolong hose life.

Refer to Figure 5-13.

1. To release pressure against the hoses, loosen the
wing nuts (1) holding the spring bar to the pump
frame. (There are four nuts total–only two are shown.)

marker during operation, the bolt will break, allowing the
marker arm to swing away rather than cause damage to
the marker.

IMPORTANT: The breakaway bolt is a 5/16-by-1 1/2­inch grade 5 on planter only (GP 802-012C). If it
breaks, it must be replaced by an equivalent grade 5
bolt to prevent marker damage.

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-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.

NOTE: 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.

End-of-Season Service

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, page 42.
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.

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 wa­ter. 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.
