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.
Prepare for Emergencies
▲ Be prepared if a fire starts
▲ Keep a first aid kit and fire extinguisher handy.
▲ Keep emergency numbers for doctor, ambulance, hospital
and fire department near phone.
Be Familiar with Safety Decals
▲ Read and understand “Safety Decals” on page 6, thor-
oughly.
▲ Read all instructions noted on the decals.
▲ Keep decals clean. Replace damaged, faded and illegible
decals.
04/04/2011 Contents Index 166-283M
2 Great Plains Manufacturing, Inc. Contents Index NTA607/2007HD
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.
Use A Safety Chain
▲ Use a safety chain to help control drawn machinery should
it separate from tractor draw-bar.
▲ Use a chain with a strength rating equal to or greater than
the gross weight of towed machinery.
▲ Attach chain to tractor draw-bar 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.
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 assistance
from a physician familiar with this type of injury.
Minimize Radiation Exposure
The DICKEY-john® RVS III Radar is an intentional radiator of RF energy. Although its radiated energy level is far
below the limits set by EN 61010-1:1993 A2:1995Chapter 12.4, it is advisable not to look directly into the
face of the unit.
The radar must radiate toward the ground and at least 20
cm (8 inches) away from a human during use to comply
with the RF human exposure limits as called out in
FCC 47 CFR Sec.2.1091. DO NOT RE-MOUNT OR
USE THE RADAR IN A MANNER INCONSISTENT
WITH ITS DEFINED USE.

Great Plains Manufacturing, Inc. Contents Index Important Safety Information 3
Handle Chemicals Properly
Agricultural chemicals can be dangerous. Improper use
can seriously injure persons, animals, plants, soil and
property.
▲ Do not use liquid seed treatments with the NTA607/2007HD
drill.
▲ 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 30m (100 feet)
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.
Confined Space
With materials loaded, or once used for hazardous fertilizers, or seeds with hazardous treatments, your hoppers
may become
“permit-required confined spaces”
under applicable statutes, regulations, insurance rules or
business policy. The vent tube structure in the hoppers
has features to assist escape, and is not for routine entry.
▲ A hopper that is full or merely appears full can be an
entrapment hazard. You can sink entirely into the material,
or into an oxygen-deficient void, and suffocate in a matter
of seconds. Bridges and crusts are especially dangerous.
▲ When hazardous fumes are present, you can be quickly
overcome even with the hopper lid open.
▲ Do not enter a hopper for material loading, material
unloading, hopper cleaning or meter maintenance.
▲ Clean hopper by power washing from outside hopper top.
▲ Perform meter maintenance by removing meters from bot-
tom of empty hopper.
▲ If obstruction removal or repair requires hopper entry, have
the work performed by a team trained in confined space
procedures. See “Hopper Entry” on page 110.

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.
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 driv-
ing on public roads.
Use lights and devices provided with implement
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 during operation.
Transport Machinery Safely
Maximum transport speed for implement is 30 kph or
20 mph. Some rough terrains require a slower speed.
Sudden braking can cause a towed load to swerve and
upset.
▲ Do not exceed 30 kph or 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 air drill in case of break-
down on the road.
▲ Keep clear of overhead power lines and other obstructions
when transporting. Refer to transport dimensions under
“Specifications and Capacities” on page 144.
▲ Do not fold or unfold the air drill while the tractor is mov-
ing
Shutdown and Storage
▲ Unfold and lower air drill.
▲ Block tires or use optional drill parking brakes.
▲ Detach and store air drill in an area where children nor-
mally do not play.

work, see specific safety information beginning on
page 118.
▲ Work in a clean, dry area.
▲ Unfold and lower the drill, put tractor in park, turn off
engine, and remove key before performing maintenance. If
work must be performed with implement raised, use center
section lift lock and gauge lock channels provided.
▲ 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.
▲ Welding: Disconnect battery ground. Protect hydraulic
lines. Avoid fumes from heated paint.
▲ Inspect all parts. Make sure parts are in good condition
and installed properly.

Preparation and Setup
This section helps you prepare your tractor and NTA607/
2007HD Drill for use, and covers seasonal tasks, and
task when the tractor/air drill configuration changes.
Before using the NTA607/2007HD Drill in the field, you
must hitch the air drill to a suitable tractor, inspect systems and level the air drill. Before using the air drill for
the first time, and periodically thereafter, certain adjustments and calibrations are required.
Initial Setup
See “Appendix B - Initial Setup” on page 162 and
“Appendix C - Option Installation” on page 163 for predelivery items (normally completed by dealer), and firsttime/infrequent setup tasks, including:
• Install seed monitor console in tractor (page 162).
• Set marker extension (page 95) and speed.
Seasonal Setup
On initial delivery, use with a new tractor, and seasonally,
check and as necessary, complete these items before
continuing to the routine setup items:
• Bleed hydraulic system (page 114).
• Wing leveling and alignment (page 129).
• Speed sensor calibration (DICKEY-john® Air Cart
Control manual).
• Blow out entire air system to remove condensation.
Check air flow at each row, for evidence of plugging.
• De-grease exposed cylinder rods if so protected at last
storage.
Pre-Planting Setup
Complete this checklist before routine setup:
❑ Read and understand “Important Safety Informa-
tion” on page 1.
❑ Check that all working parts are moving freely, bolts
are tight, and cotter pins are spread.
❑ Check that all grease fittings are in place and lubri-
cated. See “Lubrication and Scheduled Mainte-
nance” on page 132.
❑ Check that all safety decals and reflectors are cor-
rectly located and legible. Replace if damaged. See
“Safety Decals” on page 6.
❑ Inflate tires to pressure recommended and tighten
wheel bolts as specified. See “Tire Inflation Chart”
on page 147.

Hitching Tractor to Air Drill
Crushing Hazard:
You may be severely injured or killed by being crushed
between the tractor and air drill. Do not stand or place any
part of your body between air drill and moving tractor. Stop
tractor engine and set tractor parking brake before attaching
cables and hoses.
1. With the drill still on the parking jack , check that
the drill cart frame is level. See “Heights and Level-
ing” on page 26 for details on setting level.
Implement Lift and Speed Error Risks:
The frame must be level both for proper operation of the implement, and to avoid frequent re-calibration of the speed radar.
Refer to Figure 3
2. Move the tractor to near hitching position. Put the
tractor in Park and shut down the tractor. If the tractor draw bar height is incompatible with the drill hitch
height, move and/or invert the hitch to match.

2
Hitch Failure Risk:
The hitch may be mounted inverted if necessary, but always
have two (2) bolts in two holes of both tongue and hitch. See
“Heights and Leveling” on page 26 for hitch adjustments.
3. Remove hitch pin.
Back tractor to align draw bar and drill hitch.
Shut down tractor and remove key.
4. Use parking jack to lower drill tongue onto tractor
draw bar. Secure hitch to bar with pin. Secure pin
with any means provided.
5. Securely attach safety chain to a tractor anchor of
2
sufficient strength to control the drill in the event of a
hitch failure.
6. Use crank to raise jack foot. Remove pin and jack.
Refer to Figure 4
7. Store jack on stob inside right tongue tube.

Hydraulic Hose Hookup
High Pressure Fluid Hazard:
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 assistance from a physician familiar
with this type of injury.
Only trained personnel should work on system hydraulics!
Great Plains hydraulic hoses are color coded to help you
hookup hoses to your tractor outlets. Hoses that go to
the same remote valve are marked with the same color.
The fan pressure hose (yellow) must be connected to a
circuit capable of continuous flow at high volume.
Note: This implement is compatible only with tractors
having Closed Center hydraulics.
Refer to Figure 5
To distinguish hoses on the same hydraulic circuit, refer
to plastic hose label. The hose under an extended-cylinder symbol feeds a cylinder base end. The hose under a
retracted-cylinder symbol feeds a cylinder rod end.
For the hydraulic fan, connect the hose under the
retracted cylinder symbol to the pressure side of the
motor.
The fan motor further requires hookup of a (third) case
drain line, which returns lubricating/cooling fluid.
Marker hoses are provided on the cart even if markers
are not installed on the implement. See “Marker Hose
Tips” on page 162 prior to first hitching.

Low Pressure (Case) Drain Connection:
11. Attach case drain hose to low pressure drain connection. See Notice at right.
12. Connect low pressure motor return hose, marked
“SUMP”, to a high volume low pressure return port.
The sump line is distinguished by a large (1.06in/
2.7cm diameter) quick coupler.
13. Connect hydraulic hoses to tractor remotes.

04/04/2011 Contents Index 166-283M
Equipment Damage Risk:
Case Drain Hose must be attached first, prior to inlet and
return hoses being connected, to prevent damage to hydraulic
motor seals. The case drain has the smaller1⁄4in I.D. hose and
small, flat-face, low-seep connector. DO NOT connect the case
drain line to a power-beyond port.
Case Drain Hose must be detached last, to prevent damage to
the fan motor. To allow pressure relief during temperature
cycles, it is normal for this line to release small amounts of oil
even when stored with the connector elevated.

Brake Hookup (Option)
Two air drill braking (trailer braking) systems are available:
• Dual-line air system (Figure 6) with independent cable-
operated parking brake (Figure 8), and
• Single-line hydraulic (Figure 7) with independent
cable-operated parking brake (Figure 8).
In both systems, the tractor’s trailer brake remote port(s)
operate a hydraulic slave cylinder on the drill.
Tractor trailer braking systems are normally integrated
with the tractor brakes, and operate the trailer brakes
when tractor brakes are used during tractor movement.
The trailer braking system may or may not be integrated
with the tractor parking brake system.
Trailer brakes typically are not automatically engaged
when the tractor transmission is in Park, and may not be
engaged by any tractor Emergency Brake.
Both drill systems include an independent cable-operated parking brake on the drill. The tractor cannot
engage or release the drill’s parking brake system.
Null4:
Figure 6
Air Brake System
31227
Braking Hazards:
Make sure the operator understands when drill brakes are
engaged and when they are released (record tractor behavior
on page 41).
Also understand and comply with tractor operational restrictions when trailer brakes are used. For example, it is generally
necessary to inter-tie split brakes, and avoid differential
(steering braking) if trailer brakes are used.

The Provision line charges a reservoir tank on the
drill. The Brake line operates a valve system which
meters tank air to the master cylinder on the drill.
Braking Hazard:
Do not use the NTA607HD with a “single-line” air brake system. This drill is designed for transport speeds that require an
air brake system to be “dual-line”. A single-line tractor system cannot charge the tank that powers the drill brakes.
Roll-Away Hazard:
When unhitching, disconnect the red (control) line first. This
sets the brakes on the drill.

Hydraulic Brake Hookup
Refer to Figure 11
This is a single hydraulic line, connected to the tractor
“Brake” outlet.
The factory default connector is a3⁄4in poppet-style QD

Heights and Leveling
All frame sections must be at the correct height and level
to maintain even planting depth. The hitch height sets
cart frame level, and must be at a consistent height to
both maintain level, and maintain radar speed calibration.
Periodic frame-leveling adjustments should not be necessary. If you are having problems with uneven depth,
check air drill levelness and follow these procedures.
