Section 1 Safety Rules

Section 1 Safety Rules

Most accidents are the result of negligence and care­lessness, usually caused by failure of the operator to
follow simple but necessary safety precautions. The fol­lowing safety precautions are suggested to help prevent
such accidents. The safe operation of any machinery is
a big concern to consumers and manufactures. Your
3-Point Planter has been designed with many built-in
safety features. However, no one should operate this
product before carefully reading this Operators Manual.

General Operation & Repair

1. Practice safety by always thinking before acting.

2. Never allow the planter to be operated by anyone who is
unfamiliar 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.

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

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

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

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

7. After repairing or adjusting, make sure all tools and
parts are removed from the implement before attempting
to operate it.

8. Never work under a raised planter.

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

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

11. Never attempt to operate the implement unless you are in
the driver’s seat.

12. Never dismount from a moving tractor.

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

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

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

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

17. disk edges are sharp! Be careful when working in this area.

18. Detach and store implements in an area where children
normally do not play. Stabilize implements by using suit­able supports and block wheels.

19. 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 doc­tor at once!

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

21. 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. Use good judgement when transporting tractor imple­ments on the highway. Always maintain complete control
of the machine.

2. Limit transport speed to 20 mph. Transport only with a
farm tractor of sufficient size and horse power. (See
“Section 2 Planter Operation” on page 6)

3. Always make sure “Slow Moving Vehicle” emblem, and
reflectors are in place and visible prior to transporting
the machine on public roads.

4. Know your state and local laws concerning highway
safety and regulations. Comply with these laws when
transporting machinery.

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
before 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 the planter as you would when put­ting chemicals into the planter.

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

The following section was written to provide general in­formation on the planter and tractor operation.

Initial Preparation of the Planter

•

Lubricate the planter and markers as shown in

“Section 6 Lubrication” on page 24.

• Check the tires for proper inflation, refer to the Tire In-

flation Chart in "Section 9 Specifications" on
page 33.

• Check the chains for proper tension and alignment as

shown in "Section 7 Maintenance" on page 28.

• Perform all beginning of season and daily planter ser-

vice as discussed in “Section 8 Storage” on
page 30.

• Check over the planter and replace worn or damaged

parts before going to the field.

• All nuts, bolts and screws should be checked per the

Torque Value Chart in "Section 9 Specifications" on
page 33.

• The legs of the cotter pins should be spread.
Tractor Preparation

Recommended Tractor Horsepower

Minium required draw bar horsepower for field work

6-row planter 60 - 90 HP

8-row planter 80 - 120 HP

2. Adjust the tractor lower lift links to maximize lifting
height.

NOTE: To keep the planter level make sure that the
lower lift links are adjusted evenly.

Set the tractor sway blocks to minimize side sway.
Position the lift controls in float position.

3. Back the tractor up to the planter. Align the lower
links with the lower hitch holes on the planter. Insert
the hitch pins and the spacers, supplied with the
planter, according to the category of your tractor,
Figure 2-1. Lock the pins in place.

4. There are two holes on the planter for the upper
hitch point. The the tractor’s top link should be at­tached in the lower hole for Category II, see Figure
2-1. Some Category II quick couplers and all Cate­gory III top links should be attached in the upper hole,
Figure 2-1. To attach the top link some adjustment
may be required.

5. Raise the planter and look for any interference while
standing between the planter row units. Remove the
pin holding the parking stand and raise the stands to
the transport position. Put the pin in the lowest hole
in each stand, see Figure 2-1. Never work under a
raised Planter.

6. On level ground, lower the planter onto the gauge
wheels. If the planter is not level see Leveling the
Planter page 7.

NOTE: The tractor must have adequate 3 point hitch
lift capacity to lift the machine weight, attachments,
seeds and dry chemicals. Shipping weights, (refer to
“Section 9 Specifications” on page 31), do not in­clude seed, dry chemicals or optional attachments.

For tractor front end stability additional tractor ballast
may be required. Add front ballast according to your
tractor's operator’s manual.

Attaching the Planter to the Tractor

For the planter to function properly, attach the planter to
the tractor in the following manner.

1. Set the tractor wheels at double the planter row
spacing. Example: For a planter with 30" rows the
front and rear wheels should be set at 60" center to
center. This prevents soil compaction on the rows.
On hillsides andsteep slopes set the wheels as wide
as possible for maximum stability.

Transporting

!

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

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

CAUTION!

•The planter can be transported with full boxes 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.

NOTE: In order to maintain steering control, ballast
may need to be added to tractor front end. To deter­mine the amount of ballast required refer to your trac­tor’s operator manual.

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

the proper inflation as listed in the Tire Inflation Chart
in "Section 9 Specifications" on page 33.

•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 clear­ance.

Leveling the Planter

The planter must be level for the row units to function
correctly. Before leveling the planter check tire pres­sures as specified in the Tire Inflation Chart in “Section
9 Specifications” on page 31.

Adjust the lower links on the tractor to level the planter
side to side. It is best to adjust the links evenly before the
planter is attached to the tractor.

After setting the row units to the proper planting depth in

the field, stop the tractor on flat ground with the planter
lowered. Check the front-to-back level of the planter.
The bottom of the frame tube should be parallel to the
ground. If this is not parallel, adjust the upper link on the
tractor accordingly. See Figure 2-3.

If the row unit arms are not parallel to the ground, the
gauge wheel modules must be adjusted equally. Mea­sure the vertical distance between the front pivot and

10495

Gauge Wheel Module Adjustment

rear pivot of a row unit arm, see Figure 2-2. This is the
amount that the gauge wheel needs to be adjusted.
Raise the planter and loosen the jam nut (A) on the
wheel module. To lower the planter, turn the nut (B) at
the opposite end of the link counter-clockwise and clock­wise to raise the planter, see Figure 2-2. Tighten the jam
nut after reaching the desired wheel location.

Depth Adjustment

The planting depth of the row unit is controlled by 2 walk­ing gauge tires located next to the disks.

Adjust the planting depth as follows:

1. Raise the planter to remove weight from the gauge
tires.

2. Raise the T-handle and move it forward to decrease
the planting depth, see Figure 3-10. Moving the han­dle rearward increases the planting depth. Small in­crements of depth adjustment can be made by
walking the T-handle from side to side.

3. After one row is set to the desired depth, move the
T-handle on the other rows to the same location.

Row Unit Mounted Coulter

The optional coulter allows the planter to penetrate
tough ground conditions. It is recommended that either
the medium duty or heavy duty spring package be used
in conjuction with this coulter.

Coulter Adjustments

1. To adjust the coulter vertically, loosen the 3/4" jam
nut and the 3/4" x 3" long hex bolt, see Figure 3-9.

2. By turning the cam hex, rotate the cam casting to set
the desired height. For wavy coulter blades, it is rec­ommended that the coulter blade should be run
even to 1" below the disks on the row unit.

3. Tighten the bolt and jam nut to torque values in the
Torque Value Chart in "Section 9 Specifications"
on page 33.

Section 3 Row Unit Operation

If the seed trench is not closing move the handle to the
next notch back and try again. Keep moving the handle
back until the seed trench is closing, by doing this elimi­nates unnecessary down force and compaction. In
some field conditions, the T-handle can be left in the for­ward slot to minimize down force.

If one closing wheel is running in the seed trench or the

wheels are not centered over the seed trench, adjust the
closing wheels as follows:

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

2. Loosen the two 1/2" bolts.

3. Turn the press wheel adjuster left or right to center
the wheels over the seed trench.

4. Tighten the 1/2" bolts to the correct torque value list­ed in theTorque Values Chart in "Section 9 Speci-
fications" on page 33.

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 3-13.

3. Move the wheel to the rear hole and attach with the
3/4" bolt. Tighten the bolt to the correct torque value
listed in theTorque Values Chart in "Section 9
Specifications" on page 33.

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, see
Figure 3-15. To remove the seed lok, remove the clevis pin and
pull down on the seed lok mount. Reattach in the reverse order.

Section 4 Adjusting Planting Rates

Section 4 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, do as follows:

1. Select the sprocket combination for your planting pop­ulation from the" Planting Rates for Finger Pickup
Corn Meter Chart" in this section on page 21.

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

3. Release the spring tensioner on the idler,
see Figure 4-1.

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 ac­cording to the " Planting Rates for Finger Pickup
Corn Meter Chart" in this section on page 21.

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

8. Turn the idler counter-clockwise (ccw) to take up the
slack. Just before the idler sprocket reaches its limit
place the head of the sleeve lever mount in between
the two most vertical teeth of the idler sprocket. Ro­tate the spring tensioner lever over-center to apply
spring tension to hold the idler tight.

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.

12349

Spring Tensioner on Transmission

Figure 4-1

3. Measure 1/1000 of an acre. For 30" row planter
1/1000 of and 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

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,

refer to the " Planting Rates for Finger Pickup Corn
Meter Chart" in this section on page 21.

• Check the tire pressure in the gauge wheels, see Spec-

ification in " Section 9 Specifications" on page 33.

• Check for meter malfunction, see Finger Pickup Corn

Planting recommendations

To get the best planting results, follow these
recommendations:

• Plant at 5 mph

• Add 1 teaspoon of graphite to each seed hopper.

• Maintain tire pressure in the gauge tires.

• Replace worn meter parts.
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, hu­midity, speed, ground conditions, flow ability of
chemicals, and obstructions affect the application rate.

!

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

2. Slide the handle on the meter to the setting,

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

4. Fill the hoppers with chemical.

see Figure 4-2 and Granular Chemical Rate Chart
on pages 23 and 24.

the appropriate number, see Figure 4-2 and Granu­lar Chemical Rate Chart on pages 16 through 20.

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.83 to determine the pounds

per acre.

9. If required, adjust the meter setting and repeat steps

4 through 7 until the desired rate is reached.

3 to 4 pumps of grease into the zerk with universal all­purpose grease every 50 hours.

Proper maintenance can prevent unnecessary down
time and prolong the life of your planter.

Fasteners

When working on the planter torque all bolts, screws,
and nuts to the correct values listed in the Torque Val­ues Chart in "Section 9 Specifications" on page 33.
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
mechanism.

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 7-1.

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 fingersand springs by lifting thefinger
out of the slot. Average life expectancy of these
parts should be 250-300 acres of row operation.
When fingers 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 be­comes 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
projection 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 input shaft.

7. Install the cage nut and the cotter pin.

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

12353

Finger Raised/Location of Brush

Section 7 Maintenance

Spreader and Scraper

The spreader and scraper between the disks will period­ically need replacing. These components scrape dirt off
the disks and protect the seed tube.

To inspect or replace the spreader or scraper do as
follows:

1. Remove the side gauge wheel and the arm from the
row unit.

2. Remove the disk blade. Be careful, disks wear very
sharp!

3. Remove both of the 1/4" bolts holding the scraper
and spreader.

4. If the sides of the seed tube are worn, replace the
scraper and spreader.

5. Install the scraper and spreader with 1/4" bolts.
Torque the bolts to the correct values as listed in the
Torque Values Chart in "Section 9Specifications"
on page 33.

6. Install the disk and torque the bolt to the correct val­ue as listed in Torque Values Chart in "Section 9
Specifications" on page 33.

7. Install the gauge wheel according to directions un­der the Gauge Wheels heading on page 27, below.

Disk

As the disks on the row unit wear, removal of shims may
be required to maintain contact point. To remove disk do
as follows:

!

CAUTION!

Disk blades wear very sharp. Handle with care.

1. Remove side gauge wheels and arm from the row unit.

2. Remove 3/4" bolts retaining the disks.

3. Measure disk diameter, if disk measures 14 1/2" or
less replace disk.

4. If contact is to be increase, move shims from behind
disk to outside disks. This will increase the contact
between the disks.

5. Install disks and tighten 3/4" bolts to torque values in
Specification Section.

6. Install gauge wheels and arms according to direc­tions in this section.

Gauge Wheels

Periodically check gauge tires to be sure there is contact
or a 1/16" gap between the tires and disks.

For installation or adjustments proceed as follows:

1. Remove the 1/2" bolt holding arm on to the shank.

2. If the tire needs to be closer to the disk, move an ap­propriate amount of shims from the inside of the arm

to the outside, see Figure 7-2. Each shim is .050
thick.

12354

Gauge Arm, Spindle, and Shims

Figure 7-2

3. Install the arm and the shims onto the spindle. Tight­en 1/2" bolt to the correct torque value as listed in
the Torque Values Chart in "Section 9 Specifica-
tions" on page 33.

4. Check clearance or contact of the tire and disk. The
gauge wheel should fall freely when lifted. Repeat
steps 1 through 4 if necessary.

Outside Scrapers

The row units are equipped with outside disk scrapers to
remove dirt from the disks.

Periodically check the scrapers as follows:

1. Remove the gauge tires to inspect the scrapers.

2. Make sure the scrapers are contacting the disk with
some pressure.

3. If scrapers are not contacting the disks properly,
bend and twist the scrapers as required to establish
contact. If the scraper is worn too much, replace it by
removing the two 1/4" bolts. Bolt the new scraper in
place and torque the bolts to correct values as listed
in the Torque Values Chart in "Section 9 Specifica-

tions" on page 33.

Shear Pins

The planter drive line and row units are protected by
shear pins on transmission upper and lower shafts..
Check and replace bent or broken pins as required.

Chain Tension

The planter is equipped with spring loaded idlers to
maintain tension in the chains. As the chains wear and
stretch, the link(s) may be removed to provide proper
chain length and tension. Check and replace broken
springs and bushings on idlers. Forthe correct operation
of the planter check all chain routings. Refer to page 28
for the chain routing diagrams.

Section 8 Storage

Section 8 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

Inspect the hoppers for debris and clean if necessary to
prevent damage to the meters.

Clean dirt and grease from the chains and moving parts.
This will prevent the abrasive action of dirt from causing
excessive wear to chains and other parts. Lubricate the
planter according to the directions in "Section 6 Lubri-
cation" on page 26.

Check all bolts and replace worn parts on the planter to
prevent failure in the field. Make adjustments to the
planter for the field conditions to be encountered.

Ending 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 ar-

eas on the planter to protect the metal.

Lubricate the planter as outlined in "Section 6 Lubrica-
tion" on page 26. 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.

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.
