Important Safety Information
Look for Safety Symbol
The SAFETY ALERT SYMBOL indicates there is
a potential hazard to personal safety involved and
extra safety precaution must be taken. When you
see this symbol, be alert and carefully read the
message that follows it. In addition to design and
configuration of equipment, hazard control and
accident prevention are dependent upon the
awareness, concern, prudence and proper training of personnel involved in the operation,
transport, maintenance and storage of
equipment.
Important Safety Information
!
1
Be Aware of Signal Words
Signal words designate a degree or level of hazard seriousness.
DANGER indicates an imminently hazardous situation which, if not avoided, will result in death or
serious injury. This signal word is limited to the
most extreme situations, typically for machine
components that, for functional purposes, cannot
be guarded.
WARNING indicates a potentially hazardous situation which, if not avoided, could result in death or
serious injury, and includes hazards that are exposed when guards are removed. It may also be
used to alert against unsafe practices.
CAUTION indicates a potentially hazardous situation which, if not avoided, may result in minor or
moderate injury. It may also be used to alert
against unsafe practices.

▲ Lower drill, put tractor in park, turn off engine,
and remove the key.
▲ Secure drill using blocks and supports pro-
vided.
▲ Detach and store drill in an area where chil-
dren normally do not play.
Use Safety Lights and Devices
Slow-moving tractors and towed implements can
create a hazard when driven on public roads.
They are difficult to see, especially at night.
▲ Use flashing warning lights and turn signals
whenever driving on public roads.
▲ Use lights and devices provided with imple-
ment.

8/14/2006
Page 5
Transport Machinery Safely
Maximum transport speed for implement is 20
mph. Some rough terrains require a slower
speed. Sudden braking can cause a towed load to
swerve and upset.
▲ Do not exceed 20 mph. Never travel at a
speed which does not allow adequate control
of steering and stopping. Reduce speed if
towed load is not equipped with brakes.
▲ Comply with state and local laws.
▲ Do not tow an implement that, when fully
loaded, weighs more than 1.5 times the weight
of towing vehicle.
▲ Carry reflectors or flags to mark drill in case of
breakdown on the road.
▲ Keep clear of overhead power lines and other
obstructions when transporting.
Important Safety Information
3
Avoid High Pressure Fluids
Escaping fluid under pressure can penetrate the
skin, causing serious injury.
▲ Avoid the hazard by relieving pressure before
disconnecting hydraulic lines.
▲ Use a piece of paper or cardboard, NOT
BODY PARTS, to check for suspected leaks.
▲ Wear protective gloves and safety glasses or
goggles when working with hydraulic systems.
▲ If an accident occurs, see a doctor immedi-
ately. Any fluid injected into the skin must be
surgically removed within a few hours or gangrene may result.

proper tools and equipment. Refer to this manual for additional information.
▲ Work in a clean, dry area.
▲ Lower the drill, put tractor in park, turn off
engine, and remove key before performing
maintenance.
▲ Make sure all moving parts have stopped and
all system pressure is relieved.
▲ Allow drill to cool completely.
▲ Disconnect battery ground cable (-) before
servicing or adjusting electrical systems or
before welding on drill.
▲ Inspect all parts. Make sure parts are in good
condition and installed properly.
▲ Remove buildup of grease, oil or debris.
▲ Remove all tools and unused parts from drill
before operation.
Prepare for Emergencies
▲ Be prepared if a fire starts.
▲ Keep a first aid kit and fire extinguisher handy.
OFF
▲ Keep emergency numbers for doctor, ambu-
lance, hospital and fire department near
phone.
Wear Protective Equipment
▲ Wear protective clothing and equipment.
▲ Wear clothing and equipment appropriate for
the job. Avoid loose-fitting clothing.
▲ Because prolonged exposure to loud noise
can cause hearing impairment or hearing loss,
wear suitable hearing protection such as earmuffs or earplugs.
▲ Because operating equipment safely requires
your full attention, avoid wearing radio headphones while operating machinery.

instructions.
▲ Wear protective clothing.
▲ Handle all chemicals with care.
▲ Avoid inhaling smoke from any type of chemi-
cal fire.
▲ Store or dispose of unused chemicals as
specified by chemical manufacturer.
Use A Safety Chain
▲ Use a safety chain to help control drawn
machinery should it separate from tractor
drawbar.
Important Safety Information
5
▲ Use a chain with a strength rating equal to or
greater than the gross weight of towed
machinery.
▲ Attach chain to tractor drawbar support or
other specified anchor location. Allow only
enough slack in chain to permit turning.
▲ Replace chain if any links or end fittings are
broken, stretched or damaged.
▲ Do not use safety chain for towing.
Tire Safety
Tire changing can be dangerous and should be
performed by trained personnel using correct
tools and equipment.
▲ When inflating tires, use a clip-on chuck and
extension hose long enough for you to stand
to one side–not in front of or over tire assembly. Use a safety cage if available.
▲ When removing and installing wheels, use
wheel-handling equipment adequate for
weight involved.

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.

Unload seed box. Unload seed box before trans-
porting if at all possible. To do so:
• Place tarp under drill or a bucket under each
seed meter.
• Use large bucket to empty box as much as
possible. Make sure sliding seed tubes are in
the open position. Open seed meter clean out
to empty seed out of sliding seed tube and
meter.
The drill can be transported with a full box of grain,
but the added weight will increase stopping distance and decrease maneuverability.
NOTE: To maintain steering control, you may
need to add ballast to your tractor front end. Refer
to your tractor operator’s manual for ballast required.
Road rules. Comply with all federal, state and local safety laws when traveling on public roads.

Refer to Figure 18
The side gauge wheels have two, interrelated adjustments:
• angle of side gauge wheel, and
• distance between side gauge wheel and row unit disk.
Refer to Figure 19
Adjust side-gauge-wheel angle so wheels contact the row
unit disks at bottom of wheel at 2” planting depth.
At the same time, keep side gauge wheels close to the
opener disks so openers do not plug with soil or trash but
far enough out so the disks and wheels turn freely.
• If contact point is between 4 to 8 o’clock but distance to tire is not correct, then add or remove shims

Opener Down Pressure
Refer to Figure 21
Opener springs provide the down pressure necessary for opener disks to open a seed trench.
The springs allow the openers to float down into
depressions and up over obstructions.
You can adjust down pressure individually for
each opener. This is useful for penetrating hard
soil and planting in tire tracks.
Use enough down pressure to cut the seed trench
and maintain proper soil-firming over seed. Excessive opener down force will lead to premature
wear on opener components.
Refer to Figure 22
To adjust down pressure, use adjustment tool
stored under walkboard. Position tool in holes on
spring mounting plates, and pull down. Move the
adjustment cam to the new setting.

Opener Seeding Depth
A press wheel attached to each opener body controls seeding depth. To maintain consistent depth,
the relationship between the bottom of the opener
disks and press wheel is fixed upwardly.
The press wheels also close the seed trench and
gently press soil over seed. To provide consistent
soil firming, press wheels are free to move down
from normal operating position. This maintains
pressing action even if opener disks encounter
obstructions or hard soil.

Seeding Rate
Adjusting the seeding rate requires the following:
1. adjusting drive sprockets,
2. setting seed-rate handle,
3. positioning seed-cup doors,
4. checking seeding rate.
Refer to the seed rate charts on page 37. These
charts list proper sprocket sizes and seed rate
handle settings for various seeds and seeding
rates.
The seed rate charts are based on cleaned, untreated seed of average size and test weight. The
charts are based on 9.5L x 15 rib implement tires
for 15ft drills and 11L x 15 rib implement tires for
20ft and 24ft drills.
Many factors will affect seeding rates including
foreign material, seed treatment, seed size, seed
weight, field conditions, and tire pressure. You
likely will need to make minor adjustments. Set
and check the seeding rate, then readjust the rate
as necessary.
Before setting the seeding rate, rotate the gauge
wheels. Check that seed cups and drive are working properly and free from foreign material.
Adjust Drive Sprockets
Install drive sprockets for the drive type for your
desired seeding rate.
For correct drive type, refer to seed rate charts beginning on page 18. The charts list drive types as
1, 2, 3, or 4. Refer to the following table for the correct-sized sprocket for each drive type.
Reroute drive chain over sprockets and idlers as
shown in Figure 5. Move idlers into chain so
chain has 1/4-inch slack in its longest span.
Tighten idlers.

Driver and Driven Sprockets
Set same drive type on both drill sections.
Set Seed Rate Handle
Position seed rate handle for each drill box as indicated on seed rate chart. One handle is shown
in Figure 6.
To adjust seed rate handle, loosen wing nut under handle. Slide handle until indicator isjust past
the correct setting. Retighten wing nut.

Position Seed Cup Doors
For wheat and other smal seeds, move seed cup
door handles to highest position. For soybeans
and other large seeds, lower handles to second
position. If excessive seed cracking occurs, lower
handles to third position. For seed cup clean out,
move handles to fourth, wide-open position. Make
sure all handles are in same position before
drilling.
NOTE: If your results vary greatly from the charts,
you may want to repeat the calibration procedure.
8. When drilling, note acres drilled, amount of
seed added and level of seed in drill box. If
you are seeding more or less than desired,
adjust seeding rate slightly to compensate for
your field conditions.
Check Seeding Rate
1. Record the weight of an empty container
large enough to hold seed metered for one
acre.
2. Place several pounds of seed over three
seed cups on an outside end of drill box. Pull
seed tubes off these three openers.
3. Raise drill off ground.
4. Turn gauge wheel a few turns to fill cups with
seed. Turn wheel until seed drops to ground
from all three cups.
5. Place a container under the three seed tubes
to gather seed as it is metered.
6. Turn drive gauge wheel for one acre. Refer to
the chart on the next page for the exact number of tire revolutions to equal one acre.
Check that three seed cups have plenty of
seed coming into them.
7. Weigh metered seed. Subtract initial weight
of empty container. Divide by three for the
amount metered by each seed cup, then multiply by the number of drill openers for the
pounds per acre seeding rate. If this figure is
different than desired, adjust the seed rate
handle and recheck the rate.

Marker Adjustments
Bleeding Marker Hydraulics
To fold properly, the marker hydraulics must be
free of air. If the markers fold in jerky, uneven motions, follow these steps.
!
CAUTION
You may be injured if hit by a folding or unfolding
marker. Markers may fall quickly and unexpectedly if
the hydraulics fail. Never allow anyone near the drill
when folding or unfolding the markers.
!
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.
Check that tractor hydraulic reservoir is full.
1. With both markers lowered into field position,
loosen hydraulic-hose fittings at rod and base
ends of marker cylinders. If applicable, loosen
fittings on back side of sequence valve.
IMPORTANT: Never bleed an O-ring fitting. Instead, bleed a nearby pipe or JIC fitting.
2. With tractor idling, activate tractor hydraulic
valve until oil seeps out around a loosened fitting. Tighten that fitting.
IMPORTANT: JIC fittings do not require high
torque. JIC and O-ring fittings do not require
sealant. Always use liquid pipe sealant when
adding or replacing pipe-thread fittings. To
avoid cracking hydraulic fittings from over
tightening, do not use plastic sealant tape.
3. Reactivate tractor hydraulic valve until oil
seeps out around another loosened fitting.
Tighten that fitting. Repeat process until all
loosened fittings have been bled and tightened.

Folding Speed with Needle Valves
Refer to Figure 78
A needle valve controls the folding speed of markers that areplumbed separately. The needle valve
is near the rod end of the marker cylinder.
With tractor idling at a normal operating speed,
adjust marker folding to a safe speed. Turn adjustment knob clockwise to reduce folding speed or
counterclockwise to increase folding speed. Excessive folding speed could damage markers and
void the warranty.
Adjustments
41
Folding Speed with Sequence Valve
Refer to Figure 79
If markers are tied together with an optional sequence valve (P/N 113-466A), adjust folding
speed with hex adjustment screws on the sequence-valve body. There is one adjustment
screw for raising speed (1) and one for lowering
speed (2). Identify adjustment screws by markings stamped in valve body.
With tractor idling at a normal operating speed,
adjust marker folding to a safe speed. Turn adjustment screws clockwise to decrease folding speed
and counterclockwise to increase folding speed.
Excessive folding speed could damage markers
and void the warranty.
After adjusting the folding speed, tighten jam nuts
on hex adjustment screws to hold settings.

Marker Chain
There are two, interrelated adjustments for the
marker chain. Make these adjustments in the following order.
Refer to Figure 81
1. Lifting Slack. With marker unfolded, back fullthreaded adjustment bolt (1) down until head
extends as little as possible. Slowly fold marker
while observing disk. If marker disk slides
across ground more than a foot before chain
and linkage lifts it up, the chain is too long.
Shorten chain one or two links by moving clevis
(2). Check adjustment by repeating folding process.
If chain is too short when marker is unfolded, it
will prevent end of marker from dropping into
field depressions, causing skips in your marker
line. Correct this condition by lengthening chain
one or two links at clevis (2).
2. Folding Slack. Fold marker. Use full-threaded
adjustment bolt (1) to take slack out of chain
while marker is folded. Extend bolt until there is
no chain slack. Lock bolt in this position by tightening nuts (3) on either side of upright channel
(4).

Transport Carrier
When marker is folded, the second section should
rest in transport-carrier saddle.
Refer to Figure 82
To adjust front-to-rear position of saddle, loosen the
5/8 X 7-inch u-bolts (1) that fasten transport-carrier
mount onto box frame. Slide transport-carrier assembly forward or back as needed.
