Section 1 Safety Rules
Section 1
Most accidents are the result of negligence and carelessness, usually caused by failure of the operator to
follow simple but necessary safety precautions. The followingsafetyprecautions 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.
Safety Rules
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.
Alloperators 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. Diskedges are sharp! Be careful when working in thisarea.
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 anylines 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.

Planter Operation
Initial Preparation of the Planter
Lubricate the planter and markers as shown in
•
“Section 6 Lubrication” on page 26.
• 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 32.
• 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
TorqueValueChartin"Section9Specifications"on
page 28.
• The legs of the cotter pins should be spread.
Tractor Preparation
Recommended Tractor Horsepower
Minium required draw bar horsepower for field work
8-row planter 100 - 140 HP
10-row planter 120 - 160 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. The tractor Category III top link is attached in the
hole in the mast. Figure 2-1.To attach the top link
some adjustment may be required.
5. Raisetheplanterandlookforanyinterference while

ineachstand, see. Never work under a raisedPlanter.
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 Category III
3 point hitch lift capacity to lift the machine weight, attachments, seeds and dry chemicals. Shipping
weights, (refer to “Section 9 Specifications” on
page 33), 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.
Onhillsides and steepslopesset the wheelsaswide
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!
•Theplantercanbetransportedwithfullboxesofseed.
It is best NOT to because the extra weight increases
thechances 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 28.
•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 33.
Adjust the lower links on the tractor to level the planter
sidetoside. It is best to adjust the links evenly beforethe
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.
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

Depth Adjustment
Theplanting depth of the row unit iscontrolledby 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. RaisetheT-handle and move it forward to decrease
theplantingdepth,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.

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.

Closing Wheel Alignment (Refer to Figure 3-12)
If one closing wheel is running in the seed trench or the
wheelsarenotcenteredovertheseedtrench,adjustthe
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 28.
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 3-13.
3. Move the wheel to the rear hole and attach with the
3/4" bolt. Tighten the bolt to the correcttorque value
listed in theTorque Values Chart in "Section 9
Specifications" on page 28.

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
This section discusses the adjustments and settings for
seeding and chemical rates.
Adjusting Planting 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 and 22.
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.
12349
Spring Tensioner on Transmission
Figure 4-1
3. Measure 1/1000 of an acre. Refer to table below for
conversions.
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 plate counter-clockwise (ccw) to take
upthe 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
Aftersettingthetransmission, ALWAYS check the planting population in the field.
Follow these steps to check the planting population:
1. Tieup1 or more closing disks or 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.

40" 13’ - 1"
38" 13’ - 9"
36" 14’ - 6"
30" 17’ - 6"
4. Multiply the number of seeds counted by 1000. This
gives you total population.

Section 4 Adjusting Planting Rates
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,
referto the " Planting Rates for Finger Pickup Corn
Meter Chart" in this section on page 21 and 22.
• Check the tirepressure in the gaugewheels, see Spec-
ification in " Section 9 Specifications" on page 33.
• Check for meter malfunction, see Finger Pickup Corn
Meter in "Section 5 Troubleshooting" on page 25.
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.
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
Chart" on pages 16 through 24, as a starting point.
2. Slide the handle on the meter to the setting,
see Figure 4-2 and Granular Chemical Rate Chart
on pages 23 and 24.
3. If the meter has a knob, turn until the display shows
the appropriate number, see Figure 4-2 and Granular Chemical Rate Chart on pages 16 through 20.
4. Fill the hoppers with chemical.
5. Attach a plastic bag to each chemical
diffuser.
6. Drive 1320’ or a 1/4 of a mile at a normal planting
speed.
7. Weigh the contents of the bag in ounces.
8. Multiplyouncesbythefactorinthe table to determine
the pounds per acre.

Maintenance
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 28.
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. Replaceworn fingers andspringsby 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. Inspecttheindentations 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. Reassemblethemeter 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
theadjustingnutuntilitisslightlysnug.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.

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
springsand bushings onidlers.Forthe correct operation
of the planter check all chain routings. Refer to page 30

Section 8 Storage
Section 8
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.
Cleandirtand 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-
Storage
eas on the planter to protect the metal.
Lubricate the planter as outlined in "Section 6 Lubrica-
tion" on page 28. Pay careful attention tothe 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 openeradjustment bar on heavyand 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.
