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.
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.
Be Familiar with Safety Decals
▲ Read and understand “Safety Reflectors and Decals”on
page 6, thoroughly.
▲ Read all instructions noted on the decals.
▲ Keep decals clean. Replace damaged, faded and illegible
decals.
2013-09-24 Table of Contents Index 196-444M
2 3N-4010HDA Table of Contents Index Great Plains Manufacturing, Inc.
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, seek immediate medical attention
from a physician familiar with this type of injury.
Use A Safety Chain
▲ Use a safety chain to help control drawn machinery should
it separate from tractor drawbar.
▲ 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.
Keep Riders Off Machinery
Riders obstruct the operator’s view. Riders could be
struck by foreign objects or thrown from the machine.
▲ Never allow children to operate equipment.
▲ Keep all bystanders away from machine when fold-
ing/unfolding, raising/lowering markers, raising/lowering
openers, and transporting.
Check for Overhead Lines
Drill markers contacting overhead electrical lines can
introduce lethal voltage levels on drill and tractor frames.
A person touching almost any metal part can complete
the circuit to ground, resulting in serious injury or death.
At higher voltages, electrocution can occur without direct
contact.
▲ Avoid overhead lines during seed loading/unloading and
marker operations.
196-444M Table of Contents Index 2013-09-24
Great Plains Manufacturing, Inc. Table of Contents Index Important Safety Information 3
Use Safety Lights and Devices
Slow-moving tractors and towed drills 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 driv-
ing on public roads.
▲ Use lights and devices provided with the drill.
Transport Machinery Safely
Maximum transport speed for drill is 20 mph (32 kph).
Rough terrains may require a slower speed. Sudden
braking can cause a towed load to swerve and upset.
▲ Do not exceed 20 mph (32 kph). 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 national, regional and local laws.
▲ Follow your tractor manual recommendations for maximum
hitch loads. Insufficient weight on tractor steering wheels
will result in loss of control.
▲ 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. Refer to transport dimensions under
“Specifications and Capacities” on page 74.
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 hear-
ing impairment or hearing loss, wear suitable hearing protection such as earmuffs or earplugs.
▲ Because operating equipment safely requires your full
attention, avoid wearing entertainment headphones while
operating machinery.

▲ Read and follow chemical manufacturer’s instructions.
▲ Wear protective clothing.
▲ Handle all chemicals with care.
▲ Avoid inhaling smoke from any type of chemical fire.
▲ Never drain, rinse or wash dispensers within 100 feet (30m)
of a freshwater source, nor at a car wash.
▲ Store or dispose of unused chemicals as specified by chemi-
cal manufacturer.
▲ Dispose of empty chemical containers properly. Laws gen-
erally require power rinsing or rinsing three times, followed
by perforation of the container to prevent re-use.
Shutdown and Storage
▲ Clean out and safely store or dispose of residual chemicals.
▲ Secure drill using blocks and transport locks.
Lock up openers.
▲ Store in an area where children normally do not play.
Practice Safe Maintenance
▲ Understand procedure before doing work. Use proper tools
and equipment. Refer to this manual for additional informa-
tion.
▲ Work in a clean, dry area.
▲ 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.
▲ 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.

Preparation and Setup
This section helps you prepare your tractor and drill for
use. Before using the drill in the field, you must hitch the
drill to a suitable tractor and also setup the drill.
Pre-Setup Checklist
1. Read and understand “Important Safety Information” on page 1.
2. Check that all working parts are moving freely, bolts
are tight, and cotter pins are spread.
3. Check that all grease fittings are in place and lubricated. See “Lubrication” on page 64.
4. Check that all safety decals and reflectors are correctly located and legible. Replace if damaged. See
“Safety Reflectors and Decals” on page 6.
5. Inflate tires to pressure recommended and tighten
wheel bolts as specified. “Appendix” on page 74.
Hitching to Tractor
Crushing Hazard:
You may be severely injured or killed by being crushed
between the tractor and drill. Do not stand or place any part of
your body between machines being hitched. Stop tractor
engine and set park brake before installing hitch pin.
Choose a drill-hitch option (page 71) that is compatible
with your tractor drawbar.
The 3N-4010HDA has three hitch options:
• a clevis hitch,
• a small-hole, single-strap hitch or;
• a large-hole, single-strap hitch.
Always use a locking-style hitch pin sized to match the
holes in the hitch and drawbar, and at least 1
in diameter.

Tractor Hydraulic Hose Hookup
High Pressure Fluid Hazard:
Only trained personnel should work on system hydraulics!
Escaping fluid under pressure can have sufficient pressure to
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
leaks. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems. If an accident occurs,
seek immediate medical attention from a physician familiar
with this type of injury.
Refer to Figure 9
Great Plains hydraulic hoses have color coded handle
grips to help you hookup hoses to your tractor outlets.
Hoses that go to the same remote valve are marked with
the same color.
1. Connect sump return line.
2. Connect pass-through fan hoses to circuit designated for hydraulic-motor control.
3. Connect transport-lift hoses to tractor remote valve.
4. Connect fold/marker hoses to tractor remote valve.
5. Connect lock hoses to tractor remote valve.
Sump First and Last
Seals in the hydraulic fan motor can be damaged if the
return line is pressurized. Always connect the SUMP
hose first and disconnect it last. The sump hose has a
larger (1.06in) quick-connect coupling.
The hose, and large connector, labeled SUMP refers to high
volume hydraulic motor return and should always be
connected to the port on the tractor capable of handling high
volume low pressure return oil. DO NOT connect this line to
low volume case drain lines or low volume sump lines on the
tractor. See tractor manufactures recommendations for high
volume hydraulic motor return.

Hydraulic Charge
The hydraulic system was fully charged and bled when
the drill left the factory. If any changes were made prior to
delivery (such as installing markers), or there is any
question about the status of the system, see “Bleeding
Hydraulics” on page 54.
After some use, it is normal for the lift cylinders to get out
of phase. If one or more sections are not fully lifting, or
are lifting to different heights, see “Re-phasing Lift
System” on page 24.
Drill Level
A new drill has been aligned at the factory and should
not require adjustment prior to first use. Level needs to
be checked periodically, and possibly adjusted.
See “Leveling Drill” on page 56

•“Front-to-Back Level” on page 57
•“Section Alignment” on page 58
Hitch Air Cart
Consult the air cart Operator manual for detailed
instructions on hitching. Secure pintle hitch before
making seed hose connections.
Connect Seed Hoses
Refer to Figure 11
Inspect the gasket on the cart side of the bulkhead and

Install Seed Monitor Terminal
The ADC2350B cart’s standard seed monitor system
includes a virtual terminal that must be mounted in the
tractor cab. As supplied by DICKEY-john, the kit includes
an “H” bracket for any modules, and a ball swivel for
mounting the bracket in the tractor.
Mount the modules so that they are easy to observe during
planting, but do not interfere with safe operation of the tractor
in the field or on public roads.
The ball swivel includes four 10-32 screws. You or your
dealer must provide the mounting holes for the screws.
Your dealer may have alternate suction cup or clamping
brackets available if you prefer to avoid drilling holes.
See the DICKEY-john manual for harness connections.
The monitor needs to be configured with information
about your air drill, after hitching and electrical
connections. See “Setup Seed Monitor for Air Drill” in
air cart Operator manual.
Once configured for your air drill and your material, the
seed monitor performs the following functions:
On the Air Cart:
• Fan Speed monitoring
• Hopper material level monitoring
• Hopper air pressure monitoring
• Meter rate monitoring
• Ground speed monitoring

Marker Setup
If markers were ordered with the drill, they were
factory-installed. If they were ordered separately, install
them now, per the instructions included with the markers.
1. Review “Marker Operation” on page 29.
2. Bleed the marker circuit. See “Bleeding Marker
Hydraulics” on page 61.
3. If you know that your conditions require a specific
marker disk orientation, change it now. See “Marker
Disk Adjustment” on page 49.
4. Adjust marker speed. See “Marker Speed” on
page 62.
5. Set the initial marker extension, below.
6. Fold the markers.
Initial Marker Extension
Marker Extension is the distance from the centerline of
the outboard row unit on each side to the centerline of
the mark left in the ground by the marker.
The 3N-4010HDA is symmetrical, and the values are the
same on each side and independent of next pass
direction. On a dual-marker drill, set each side.
To change marker extension:
If this is not the first adjustment to marker length.
1. Position drill on level ground and lower to planting
position.
2. Fully extend a marker.
3. If you plan to change the marker blade angle or
invert the blade, make that adjustment now (see
page 49).
4. Pull forward several feet to leave a mark.
5. Sighting along a line parallel to a tool bar, measure
the distance from the outside row unit centerline
(opener discs or furrow) to the mark. If the distance
matches the suggested value above, no marker
extension adjustment is needed.

Operating Instructions
This section covers general operating procedures. It
assumes that Setup items have been completed for both
drill and air cart.
Experience, machine familiarity and the following
information will lead to efficient operation and good
working habits. Always operate farm machinery with
safety in mind.
General Description
Drill hydraulic functions (except fold and markers) are on
separate circuits for lift, lock, and air cart. The Fold circuit
may be shared, if optional Markers are present and a
selector valve is installed.
Field operations are entirely controlled from the tractor
cab. Setup and loading operations require setting valve
handles on the drill and air cart.
Planting Operation
Via an adjustable lift switch on the drill, the 3N-4010HDA
controls the meter drive clutch on the air cart, turning it
on and off as the drill is lowered and raised.
Seed is delivered to the row units by air, powered by the
fan on the air cart. Seed rate is determined by air cart
setup, and the cart meter rate self-adjusts for changes in
ground speed. Seeding stops when motion stops or the
drill is raised.
The metered seed is carried by air through the hoses to
the distribution towers on the drill. These towers then
divide the air and seed into individual rows.
Seeding depth and furrow coverage are controlled by
row unit down pressure and depth adjustments.
Pre-Start Checklist
❑ Lubricate the drill as indicated under Lubrication,
“Maintenance and Lubrication” on page 53.
❑ Check the tires for proper inflation according to “Tire
Inflation Chart” on page 74.
❑ Check for worn or damaged parts and repair or
replace before going to the field.
❑ Check all nuts, bolts and screws. Tighten bolts as
specified on “Torque Values Chart” on page 75
❑ Check drill lift switch on drill
❑ Complete all pre-start checklist items on the air cart.

Raising and Lowering (Lift)
The drill Lift function is used only when the drill is
unfolded. The drill must be fully lifted and locked when
folded.
When unfolded, the lift function is used for headland
turns, adjustments and maintenance, and in preparation
for folding.
Raising
1. Operate the tractor lever for the Lift circuit to fully
extend the lift cylinders. Set lever to Neutral to hold
at lift. If raising for turns or short field moves, lift is
complete.
2. If lifting for adjustments, maintenance or in preparation for Fold, install lift locks.
Lift Locks
Refer to Figure 17
3. Remove lock channels from storage locations on the
rockshaft.
4. Install lock channels over extended lift cylinder rods.
Six cylinder rods total.
Lowering
Lower drill only when fully unfolded.
1. Extend lift cylinders to fully raised (in case cylinders
have settled against lock channels). Set circuit lever
to neutral.
2. Remove lock channels and stow them at their storage locations.
3. Retract lift cylinders and fully lower drill.

Re-phasing Lift System
Over a period of normal use the cylinders may get out of
phase. This will cause some drill sections to run higher
than others. To rephase cylinders:
1. Raise the drill completely and hold the hydraulic
remote lever on for several seconds until all cylinders
are fully extended. Do this every 3 or 4 times you
raise drill out of ground.
2. When all cylinders are fully extended, momentarily
reverse hydraulic remote lever to Retract height
(6.3cm) to maintain levelness.

Fold Selector Valve
If optional markers are installed the hydraulic circuit is
shared with the fold cylinders. A selector valve on the drill
switches the circuit between Fold and Markers.
Refer to Figure 20
(a front view of the valve set for Marker operations)
The drill selector valve is located on the left wing tool bar
near the tongue drawbar.
