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 5, thor-
oughly.
▲ Read all instructions noted on the decals.
▲ Keep decals clean. Replace damaged, faded and illegible
decals.
10/06/2010 150-290M
2 1007NT Great Plains Manufacturing, Inc.
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.
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.
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
150-290M 10/06/2010
Great Plains Manufacturing, Inc. 3
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 20 mph (32
kph). 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.
▲ Comply with state and local laws.
▲ Do not tow an implement that, when loaded for transport,
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.
A
Handle Chemicals Properly
Agricultural chemicals can be dangerous. Improper use
can seriously injure persons, animals, plants, soil and
property.
▲ Do not use liquid treatments with 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 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
▲ Lower drill, put tractor in park, turn off engine, and remove
the key.
OFF
▲ Secure drill using blocks.
▲ Detach and store drill in an area where children normally
do not play.

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.
Practice Safe Maintenance
▲ Understand procedure before doing work. Use proper tools
and equipment. Refer to this manual and your Parts 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.

Hitching Tractor to Drill
In lowered (field) position, with the drill frame set at the
desired height via depth control valve (see page 29), the
tongue must be level.
When hitching for the first time:
• it is necessary to adjust hitch height (page 74), and
• it may be necessary to change the position of the clevis or pintle hitch in the tongue weldment (page 75).
Either Hitch
1. Back tractor close to hitch, and use parking jack to
match heights between tractor hitch/drawbar and drill
hitch.
2. For pintle hitch, skip to step 7.

Hydraulic Hose Hookup
Connect hydraulic system to tractor before lifting the drill.
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 immediate medical attention from a physician familiar
with this type of injury.
The hydraulic system of the 1007NT drill has one circuit,
which controls two functions:
• Forward lift with depth-control stop valve.
• Rear lift-assist, which is fully retracted in the field.
Note: Prior to first use, adapt the
1
tings to connectors compatible with the tractor.
Use liquid pipe thread sealant (not tape) on NPT.
A poppet style QD(Quick Disconnect) to

coupler is available as Great Plains part 811-856C.
Refer to Figure 4
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.
12. Connect the hydraulic hoses to the tractor remotes.
Re-phasing Cylinders
The lift cylinders may, after a period of time, get out of
time or phase. The effects of this can be seen when not
all cylinders are fully extended at full lift.
To re-phase the cylinders, raise drill completely and hold
tractor hydraulic lever on for a few seconds to give cylinders time to re-phase.
Each time drill is raised out of ground momentarily
reverse hydraulic lever immediately after re-phasing to
allow cylinders to retract about
1
⁄
in (13mm). This helps
2
in maintaining a level drill.
Note: Having cylinders become gradually out of time is
different than air trapped in the system. Each condition is corrected differently. Perform “Hydraulic
Setup” on page 73 to purge air from the system.

Electrical Connection
Refer to Figure 6
(which depicts both European and North American style connectors - if your implement does not have the correct
connector for your tractor, contact your Great Plains dealer)
13. Plug the drill lighting connector into tractor outlet.
14. Coil-up and tie-up excess cable, allowing enough
slack for turns and ridges.
Leveling the Drill
Before making depth control adjustments (page 29):
• the hydraulic system must be free of air (page 73),
• the cylinders must be re-phased (page 15), and;
Figure 6
Lighting Connectors
27172
26467
• the drill must be level front to back and side to side.
Drill level needs to be checked prior to first use, and periodically thereafter. See “Leveling Drill” on page 44.

Pre-Start Checklist
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 immediate medical attention from a physician familiar
with this type of injury.
1. Carefully read “Important Safety Information” on
page 1.
2. Lubricate drill as indicated under “Lubrication” on
page 47.
3. Check all tires for proper inflation. See
Chart
” on page 58.
4. Check all bolts, pins and fasteners. Torque as shown
in “Torque Values” on page 59.
5. Check drill for worn or damaged parts. Repair or
replace parts before going to the field.
6. Check hydraulic hoses, fittings and cylinders for
leaks. Repair or replace before going to the field.
7. Rotate each ground drive wheel to see that the
drives and meters are working properly and free
from foreign material.
“Tire Inflation
Watch your step when walking on drill ladder and walkboard.
Falling from drill could cause severe injury or death.

Drill Lift/Lower
Raising and lowering the drill relies on one front cylinder,
and one rear lift-assist cylinder. Both cylinders are on the
same circuit and operate in unison, although at different
rates front to back.
When lowered, the rear lift-assist arms raise more rapidly
than the front rockshaft, resulting in the rear caster
wheels being off the ground during planting. The rear
wheels play no role in setting planting depth.
Lowered position is set by a depth control valve, which
stops oil flow to the cylinders at a height you determine.
Raised position is normally fully raised, then lowered
onto lock channels for transport.
Raising
1. Activate the lift circuit lever to Extend the lift cylinders
fully. Set circuit to Neutral.
Raising for Transport, Parking or Storage
Refer to Figure 7 and Figure 8
3. Set tractor parking brake and shut off tractor.
4. Rotate the lock channel at the front cylinder until
the polymer bumpers snap around the rod. Place
lock channel on lift-assist cylinder.
Note: If any cylinder is not sufficiently extended to permit
lock channel engagement, system needs to be rephased (page 15)
5. Slowly move lift circuit lever to Float, allowing cylinders to settle on lock channels.
6. Set circuit to Neutral to transport.
Leave circuit in Float for parking, storage or maintenance.
Raising after Transport, Parking or Storage
7. Extend circuit for lift cylinders, until cylinders clear
lock channels. Set circuit to Neutral.
8. Swing front lock channel away from cylinder rod and
remove lift-assist lock channel from rear cylinder rod.
9. Store lift-assist lock channel on side of mount .
Secure pin in hole provided.

Lowering
If lowering from transport, parking or storage, it is first
necessary to raise the drill, and disengage the lock channels.
10. Move the tractor remote circuit lever to Retract.
Normally, drill lowers until openers contact the ground,
rear lift assist wheels rise off ground, and rockshaft continues to lower until depth control stop halts front lift cylinder retraction.
11. Move lift circuit lever to Neutral.
See page 29 for depth control stop valve adjustments.
Crushing Hazard - Rely on circuit Neutral to hold the drill
raised only for field turns. Use lock channels for all other
raised operations: transport, parking, maintenance and storage.

Caster Pivot Locks
Refer to Figure 9
To prevent side movement of the drill when transported
by trailer, the lift-assist casters may be locked in their full-
reversing orientation. A spring-loaded pin engages a
cutout in the caster pivot plate, preventing rotation.
Use this feature only for trailer transport. Do not use
these locks for towing drill on own wheels or field operations.
2
Locking Casters
Refer to Figure 9 and Figures 7 and 8 on page 18
1. With drill hitched, raise drill (page 18). Install lift lock
channels.
2. Begin backing drill toward trailer until casters swing
into reverse and drill is aligned with trailer. Stop a
short distance from the trailer.
3. Lift locking cross-pin out of upper (disengagement) detents. Rotate cross-pin and release into
deeper locking detent

Transporting
The drill may be transported on its own wheels, or on a
trailer.
Transport on Drill Wheels
Before transporting with a tractor, check these items:
1. Check that tractor is sufficient for towing the drill.
Tractor must have at least 80 horsepower (60 kW).
Use a tractor with adequate weight relative to drill.
See the tables below for typical drill weights.
2. Unload drill boxes. The drill can be transported with
full boxes of material (other than native Grass), but
the added weight increases stopping distance and
decreases maneuverability. Unload before transporting if possible.
3. Raise drill completely (page 18).
4. Install lock channels on lift cylinders (page 18).
Note: The cylinder locks can be secured or removed only
with drill fully raised.
Approximatea 6in Configuration Weights
Unstable Load Hazard: Tow the drill only with a tractor with
sufficient power and that weighs at least 2/3 (67%) of the drill.
An implement that weighs more than 150% of the towing vehicle is a dangerously unstable load in braking and turning.
Excessive Speed Hazard: Towing the drill at high speeds can
lead to loss of vehicle control and a serious road accident,
injury and death. To reduce the hazard, do not exceed 20 mph.
Failure of hydraulic cylinders or tractor circuit during transport will cause drill to drop suddenly, which could lead to serious road accidents, injury or death. To prevent an accident,
always install cylinder lock channels before transporting drill.
Do not transport with Native Grass box loaded. Heavier mix
components settle to the bottom, which can prevent drive system from operating or cause irregular seed rate and population distribution.
Approximatea 7.5 Configuration Weights
a. Weights are approximate, and can vary by hundreds of pounds based on material density, press wheel options, accessories and user
modifications. Additional “Weights” figures presume 10 each 100 pound suitcase weights.

For Any Transport
Keep Clearance in Mind
Remember that the drill may be wider than the tractor.
Allow safe clearance.
Observe Road Rules
Comply with all national, regional and local safety laws
when traveling on public roads.
Trailer Transport
Loading Trailer
1. Hitch raised and locked drill to suitable tractor.
2. Carefully line-up the tractor, drill and trailer, so that:
a. no turns are needed for the final movement, and
b. the casters are fully reversed.
3. Lower caster swivel lock pins to lock position
(page 19).
4. Carefully back the drill onto the trailer bed.
Unstable Load Hazard: Do not transport on a trailer of insufficient width or length. Unless all transport tires are on the
bed, too few openers are supporting the entire drill. The load
may spill, with risk of serious injury or death to anyone
nearby, and certainty of major equipment damage.
5. Remove transport locks and lower the drill (page 18).
6. Unhitch the tractor.
7. Secure the load with cargo straps or chains.
Unloading Trailer
1. Release cargo straps or chains.
2. Hitch suitable tractor with available hydraulic remote
(page 14).
3. Confirm that caster pivot swivel locks are still in place
(page 19).
4. Raise drill (page 18).
5. Install lift-assist cylinder transport locks (page 18).
6. Carefully tow drill from trailer.
7. Remove caster pivot swivel locks.
Load Maneuvering Hazard - Use care and planning when
loading or unloading the drill in trailer transport. The rear
casters may turn and force the drill off the trailer.
▲ Make sure the trailer is rated for the load.
▲ Make sure the trailer is wide enough for the load.
▲ Make sure the load is secured properly.

Loading Materials
Fully loaded with dense seed and fertilizer, the drill
weighs an additional 1970 lbs (894 kg). Include this
weight when checking tractor capability.
The drill must be hitched for seed loading.
Load slightly more material than needed, because consumption rates can vary between compartments even
though the furrow rates are identical.
1
Main Seed Box Loading
1. Check that all meter doors are positioned for the
seed size, and not set for clean-out. See “Position
Seed Cup Doors” in seed Rate Manual. If loading
prior to transport, set them to position 1 (smallest
seed).
2. Install or remove optional seed plugs as desired for
the row spacing planned. See “Seed Tube Plug
(Small Seeds)” on page 55.
If loading prior to transport, and calibration has not yet
been done, set Seed Rate Handle to 0. At 0, and with the
doors at 1, no seed can leak during transport.
3. The main seed box lid handle is also a latch. It needs
to pivot up to release the lid.
4. Load seed evenly into compartments.
To reduce wear on unused boxes that may also be
present:
• Remove final drive chain for small seed box.
• Remove ground drive chain in Native Grass (right
wheel).
Take all prescribed material
safety precautions.

Loading Small Seeds Box
1. If loading prior to transport, and calibration has not
yet been done, set Seed Rate Handle to 0. At 0, no
seed can leak during transport.
2. Take all necessary materials safety precautions if the
seed is treated.
3. The Small Seeds lid is held closed by two external
rubber latches. Pull them up and to the rear to
release the lid.
4. Load seed evenly into compartments.
5. To reduce wear, remove main shaft drive chains for
main seed boxes.
150-290M 10/06/2010
Loading Fertilizer
Fully loaded with dense fertilizer, the drill can weigh an
additional 700 lbs (318 kg) or more. Include this weight
when checking tractor capability.
Load fertilizer after transport if possible. Some spillage
can occur through meters during transport, even with the
drive system disengaged.
1. Check that fertilizer clean-out door is closed and all
latches are secure.
2. If loading prior to transport, and calibration has not
yet been done, set Rate Adjuster to 0. At 0, no fertilizer can leak during transport.
3. The fertilizer lid is held closed by a spring-loaded
bumper. Lift smartly at the handle to release it.
4. Load fertilizer evenly into fertilizer compartment.
5. To reduce wear, remove drive chains for seed boxes
not used.
Great Plains Manufacturing, Inc. Operating Instructions 23
Unused Boxes
Unless steps are taken, all meter shafts of all boxes are
operating whenever the drill is lowered and moving. To
prevent needless wear, disable any unneeded ground
drive or box(es).

Ground Drive Lock-Up
On a drill with Native Grass, both left and right ground
drives will be operating unless one is disengaged.
To disengage, disconnect the ground drive spring rod of
the unused drive is from its normal (inner) operating
1 2
lug , and reconnect it to a (outer) hold-up lug . This
operation requires a hoist or jack.
Refer to Figure 11
1. Raise the drill and install lift locks (page 18).
2
2. Loosen the nut at the lower spring rod bolt .
3. Hoist or jack up the ground drive arm until the lower
bolt is loose. Remove the nut, washer and bolt.
4. Hoist or jack the arm up again until the spring rod
clevis is aligned with the hole in the outer lug of
the arm.
5. Insert the bolt, and secure with washer and nut.
In this configuration, the locked-up drive never touches
the ground and does not turn.
This locked-up configuration does not disengage any
chains, and may also be used to make the ground drive
easier to access for calibration (page 33).
