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. The sig­nal words are:

!

DANGER!

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.

Keep Riders
Off Machinery

Riders obstruct the operator’s view.
Riders could be struck by foreign
objects or thrown from machine.

▲ Never allow riders on implement.
▲ Never allow children to operate

equipment.

Great Plains Mfg., Inc.

Use Safety
Lights and Devices

Slow-moving tractors, self-propelled
equipment 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 implement.

Transport
Machinery Safely

Maximum transport speed for imple­ment is 25 kph. Some rough terrains
require a slower speed. Sudden
braking can cause a towed load to
swerve and upset.

▲ Do not exceed 25 kph. Never

travel at a speed that does not

allow adequate control of steering
and stopping.

▲ Comply with state and local laws.
▲ Reduce speed if towed load is not

equipped with brakes.

▲ Do not tow an implement that,

when fully loaded, weighs more
than 1.5 times the weight of tow­ing vehicle.

Use A Safety Chain

▲ Use a safety chain to help con-

trol drawn machinery should it
separate from tractor drawbar.

▲ Use a chain with a strength rat-

ing equal to or greater than
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 tow-

ing.

Practice Safe Maintenance

▲ Understand procedure before

doing work. Use proper tools and
equipment. Refer to this manual
for additional information.

▲ Work in a clean, dry area.
▲ Lower implement to ground, put

tractor in park, turn off engine,
and remove key before performing
maintenance.

▲ Allow implement to cool completely.
▲ 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 implement before oper­ation.

Prepare for Emergencies

▲ Be prepared if a fire starts.
▲ Keep a first-aid kit and fire extin-

guisher handy.

▲ Keep emergency numbers for

doctor, ambulance, hospital and
fire department near phone.

911

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.

Avoid High
Pressure Fluids Hazard

Escaping fluid under pressure can
penetrate skin, causing serious
injury.

▲ Avoid the hazard by relieving

pressure before disconnecting
hydraulic lines.

▲ Use a piece of paper or card-

board, 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 doc-

tor immediately. Any fluid injected
into the skin must be surgically
removed within a few hours or
gangrene may result.

Safety at All Times

Thoroughly read and understand this
manual before operation. Refer to
Safety Decals, page 4. Read all
instructions noted on decals.

▲ Be familiar with all implement

functions.

▲ Operate implement from driver’s

seat only.

▲ Do not leave tractor or implement

unattended with engine running.

▲ Do not dismount a moving tractor.

Dismounting a moving tractor could
cause serious injury or death.

▲ Do not stand between tractor and

implement during hitching.

▲ Keep hands, feet and clothing

away from power-driven parts.

▲ Wear snug-fitting clothing to avoid

entanglement with moving parts.

▲ Watch out for wires, trees, etc.,

when raising implement. Make
sure all persons are clear of work­ing area.

▲ Do not turn tractor too tight, caus-

ing implement to ride up on
wheels. This could result in injury
or equipment damage.

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 to allow you to stand to
one side–NOT in front of or over
the tire assembly. Use a safety
cage if available.

▲ When removing and installing

wheels, use wheel-handling
equipment adequate for weight
involved.

Introduction

Great Plains Mfg., Inc.

Great Plains welcomes you to its growing family of new
product owners. This implement has been designed with
care and built by skilled workers using quality materials.
Proper setup, maintenance and safe operating practices
will help you get years of satisfactory use from the
machine.

Description of Unit

The NTA 2000 is a pull-type seeding implement. The
implementhas No-till coulters and openers intricately con­nected on a center pivot. No-till coulters mounted on the
front frame zone-till strips for seed furrows. Straight-arm
openers on the rear frame prepare seedbeds and place
the seed. The pivoting action of the frames allows drill
openers to track the coulters. A contact-drive tire powers
the seed meter from a transport tire. The tongue cylinder
and transport tires control the coulter and opener depth.
Transport cylinders raise the drill for turns and transport.
The drill is equiped with hydraulic brakes which work in
conjuction with the tractor brakes. There is a seperate
park brake lever which locks the brake when appllied.

Intended Usage

CAUTION!

You may be injured or killed by a folding or unfolding opener or
coulter frame.

Bleeding Fold Hydraulics

Check hydraulic fluid level in tractor reservoir and fill to
proper level. Add fluid to system as needed while cycling
new cylinders. Fold hydraulic capacity is 7.5 liters (2
gallons).

If drill is folded:

1. Makesure theopener foldlock pins arein place. Loos­en the fittings at the rod endof each coulter fold cylin­der and at the base end of each opener fold cylinder.
Supply oil as to unfold the drill. As oil begins to seep
from the loosened fittings, tighten those fittings. Do
not unfold the wing sections at this time.

2. Makesure theopener foldlock pins arein place. Loos­en the fittings at the base end of each coulter fold cyl­inder and at the rod end of each opener foldcylinder.
Supplyoil as tofoldthe drill. As oilbegins to seepfrom
the loosened fittings, tighten those fittings. Continue
supplying oil as to completely fold the drill for at least
five seconds.

3. Remove the fold lock pins and unfold the drill.

!

CAUTION!

Use extreme caution because some sudden dropping of the
wings may occur if a small amount of air still remained in the
cylinders.

4. Fold and unfold the drill three more times.

2. Withtractor idling, activatetractor hydraulicvalveuntil
oilseeps out around a loosenedfitting. Tighten that fit­ting.

IMPORTANT: JIC fittings do not require high torque. JIC
and O-ring fittingsdo 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.

4. Cycle both cylinders completely in and out at least
threetimes to completely purge airfrom cylinders and

Transporting

!

WARNING!

Towing the implement at high speeds or with a vehicle that is
not heavy enough can lead to loss of vehicle control. Loss of ve­hicle control can lead to serious road accidents, injury and
death. To reduce the hazard:

• Do not exceed 25 kph (20 mph).

• Do not tow an implement that, when fully loaded, weighs

more than 1.5 times the weight of the towing vehicle.

1. Check that implement is securely hitched to a suffi­cient tractor. Refer to Hitching Tractor to Implement,
“Preparation and Setup,” Page 9. Makesure safety
chain is secured to tractor.

2. Unload seed box before transporting if atall possible.
The implement can be transported with a full box of
grain, but added weight will increase stopping dis­tance and decrease maneuverability.

3. Check that tires are properly inflated. Refer to Tire In-
flation Chart,“Appendix,” page 49.

4. Know implement dimensions in transport position.
Choose a route that provides adequate clearance
from all obstructions. Refer to “Specifications and
Capacities,” page 43, for dimensions.

5. Plug light-harness lead into tractor connector. Always
use warning lights when transporting drill.

6. Release parking brake.

Adjustments

Seeding Depth

To set drill seeding depth, you must:

• Set coulter depth with tongue cylinder and gauge
wheels.

• Set opener depth with T-handles on press wheel.

• If field conditions make it necessary, increase coulter

downpressure by addingtractor weights toframe. Re­fer to Added Weight, page 25.

• If necessary, adjust individual coulters or openers to
seed in tire tracks.

The following is an introduction to how the coulters and
double-disk openers are designed to control seeding
depth.

Coulters

A no-till coulter is mounted on the coulter frame directly
aheadof eachopener onthe drill.The coulterscut through
heavy trash and make a tilled path in the soil for the
openers.

Coulter cutting depth is controlled by the tongue cylinder
and the gauge wheels. You also can change the depth of
individual coulters by changing coulter-mounting height.
Refer to Coulter Depth, page 23, for informationon these
adjustments.

The amount of coulter down pressure needed to cut a soil
groove varies with soil conditions. Adding weight orshort­ening the coulter spring increases coulter down pressure
and cutting force. Refer to Coulter Down Pressure, page
25, for more information on these adjustments.

Openers

Opener double disks travel in the coulter path to make a
seed bed. Mounted on the rear of each opener is a press
wheel. The press wheels control opener seeding depth
and firms the seed into the soil.

To maintain a consistent seeding depth, upward press
wheel movement is restricted by an independently adjust­able stop on each opener. Moving this stop changes the
depth at which seed is placed. The mounting height of
openers that run in tire tracks also canbe changed. Refer
to Opener Depth, page 26, for information on these
adjustments.

The amount of opener down pressure needed to cut and
widen the coulter grooveand tofirm the seed into the soil
varies with soil conditions. Openerdown pressurecan be
adjusted for all openers or individual openers. Refer to
Opener Down Pressure, page 27, for information on how
to make these adjustments.

NTA 2000 148-561M

23

Coulter Depth

Adjust coulters to run 13mm to 25mm (1/2” to 1”) below
the drill openers. Coulter depth can be adjusted hydrauli­cally for all coulters or manually for individual coulters.

Hydraulic Control

Make the following adjustment when drilling in level
ground with the seed box half full.

1. Retracttonguecylinder totransferthetractor weightto
the coulter toolbar.

Great Plains Mfg., Inc.

Refer to Figure 23

2. Lowerthe drill and set tongue cylinder so coulters are
at desired depth. Note the setting on cylinder gauge
so you can return to the same depth.

NOTE: Use cylinder gauge only as a reference. Gauge
does not measure actual coulter depth.

Refer to Figure 24

3. Adjust the cylinder spacers on the transport cylinders
so the opener bodies are levelwith the ground when
the coulters and openers are at the desired depth.

Coulter Wing Adjustment

Set the coulter wing frames so the wing coulters run at
exactly the same depth as the center framecoulters. This
is accomplished with two adjustments.

Refer to Figure 26

1. Add or removespacer shims from behind coulter
frame stop studs. The studs should allow the coulters
to drop slightly below the desired operating depth to
allowthe coulter lockpins to beinstalled and removed
easily.

Refer to Figure 27

2. Adjust the lock link trunnion nuts so the wing coulters
run exactly the same depth as the center frame coul­ters. The coulters must be lowered into the ground so
soilpressure isforcing thewings upwardto makesure
the lock link trunnions are properly set.

Coulter Mounting Height

You can change the depth of individualcoulters by adjust­ing coulter-mounting height. If you adjust coulter height,
be sure to rebolt coulters vertically straight and correctly
spaced. To raise or lower individual coulters:

1. Loosenmountingclamps andadjust coultertodesired
height. Do not lower coulter spring bar below top U­bolts on coulter clamp.

Refer to Figure 28

2. To re-tighten clamps. Snug hex-head clamp bolts (1)
just until U-bolts are tight on each side of spring bar.

3. Tighten nuts (2) on U-bolts.

4. Finish tightening hex-headclamp bolts (1).

NOTE:Evenwhen coulter is heldsecurely,theremay be a
gap between clamp halves.

Coulter Down Pressure

Added Weight

Refer to Figure 29

Inhard soil conditionswhere coulter penetrationis limited,
you can add suitcase weights to brackets on the hitch
frame.The weightbracketsare locatedon eachside ofthe
drill fan. Adding weight on the hitch frame provides the
bestweight distributionfor no-tilldrilling.You canadd up to
907kg (2000lbs) of additional weight. Place an equal
amount of weight on each weight bracket.

Coulter Springs

Refer to Figure 30

Coulter-spring length is preset at the factory to 254 mm
(10”), giving coulters an initial operating force of 181 kg
(400 lbs). This setting is adequate for many difficult no-till
conditions. For lighter no-till conditions where rocks or
other obstructions are a problem, you can reduce coulter
down pressure to give coulters better impact protection.
Refer to the following chart for adjusting coulter down
pressure.

Refer to Figure 35

Aleaf spring is locatedjust ahead of thevertical pivot. The
springis designedto provide justenough forceto keepthe
opener frame square and stable for turning at field ends
and to add stability for drilling in rough field conditions.
Proper leaf-spring adjustment is important for smooth
implement operation.

1. To adjust properly, square the opener frame to the
coulter frame and adjust 3/8” U-bolts (1) on each side
untilleaf-spring rollers (2)just makecontact with roller
pads (3) on opener frame. When the U-bolts are ad­justed properly the opener frame should be square

is folded. Use extreme caution when folding the drill for
thefirst time afterthe harrowsare installed. Slidethe light
bar brackets forward or backward as necessary so the
wing opener press wheels and wing harrowsdo not con­tact the lights.

4. To adjust the transport height of the center harrow
section, raise the drill and install the transport lock
channels on the transport cylinders and the tongue
cylinder.

5. Removethe7/16” lock nuts(1) and7/16” x 23/4” bolts
(2) from the center pull arms and the chain links on
chain (3).

6. The center section must rest low enough in the trans­port position to allowthe wing sections to foldoverthe
top of the center section without contacting it. This po­sition is slightly lower than the maximum down posi­tion of the wing sections.

7. Select achain link to adjust the transport heightof the
centersection. Carefully fold the drill tomake sure the
wing harrow sections do not contact the center sec­tion. Make adjustments as necessary to get the max­imum center section transport height without wing
section contact.

8. Make sure both chains are adjusted to the same
length so the section raises and lowers evenly.

Feed Flaps

Spring loaded flaps, one below each roller allows the
seedingof a widerange of seedsizes and areused to pos­itively control the flow of small seeds to large seeds
through the feed rollers without causing bruising orcrush­ing. They also act as a safety devise for the feed rollers.
The spring loaded flap “gives” to allow a stone or other
obstructions through without damaging the rollers.

Refer to Figure 46

1. The flaps under all the rollers are adjusted by a single
leverat the right hand end of the hopper. A series of
notches in the guide bracket set the lever to the re­quired flap opening. Position 1 is the upper setting at
which the flaps are closest to the feedroller.

Refer to Figure 47

Note:Each flap shouldjust touch thefeed rollerat position

1. This is factory set, however, if adjustment is required,

tightenor slackenthe lockscrewbelow therequired flap to
keep all flaps equal across the meter.

Therecommended position forthe Feed Flaplever setting
for different seed types is as follows:

• Position 1: Small seeds e.g. rape, when the flap is
closest to the feed roller.

• Position 2: Cereals e.g. wheat and barley.

• Position 3: Large seeds e.g. peas and beans.

Note:Refer to the seed ratecharts forproper feed flapset­ting.

Half Width Shut-Off

Refer to Figure 48

Half width shut-off provides for:

a. Seedingof anarrow widthwhen finishinga field to

preventdouble seeding.

b. To start a field in the correct sequence whentram-

To disengage, insert tool into clutch grooves and rotate
the clutch until the two drive roll pins are in line. Slide
clutch to the left untilthe rightdrive rollpin isdisengaged.
Rotate clutch one quarter turn back to lock it onto the left
drive roll pin to prevent the clutch from reengaging.

Note: The left- hand side of the feedmechanism is disen­gaged. Re-engage by rotating the clutch from it’s lock po­sition and allow it to slide back to the right.

NOTE: CHECK TO BE SURE THE CLUTCH HAS

Checking the Seeding Rate

The following procedure should be followed to cali­brate the drill for different seed types. Note that the
following factors may affect seeding accuracy:

• Errors in land area which are affected by wheel
slip, operator judgement and by inaccurate knowl­edge of field size.

• Errors in metering which are affected by seed
treatments, seed size, variety, moisture content
and seed bulk density.

To calibrate the drill, an accurate set of scales will be
required.Other equipment issupplied with thedrill and
includes calibration trays and handle.

Procedure

Refer to Figure 49

1. Release the two black plastic lock screws above
each venturi unit by loosening, sliding the knob up
and re-tightening.

2. Pushthe leftand right venturiunits forwardtoclear
the feed units.

Refer to Figure 50

3. Remove calibration tray (a) from storage position
abovethefeedrollers byloosening center knob(b)
and sliding lock tab down.

Refer to Figure 51

4. Positionthe calibrationtrays under the feedrollers.

5. Refer to the “Seed Rate Charts,” page 44, for the
seed tobe sown. Set to the “High” or “Low” speed,
adjust the flaps below the feed rollers to the re­quired position andadjust the variator lever to the
setting indicated on theguide chart to give the tar­get rate.

6. Ensure that the drill is not in a tramlining bout so
that all the feed rollers turn when the seedshaft is
rotating.

7. Fill the hopper withatleast 50 kg (110 lbs) of seed
to ensure that all the feed rollers are covered
throughout the test.

Refer to Figure 52

8. Positionthe crank handle on the input point of the
Variator and rotate clockwise to “prime” the feed
mechanism. It is important to turn the handle at
least 50 turns before calibrating to ensure seed is
flowing correctly through the system. Empty the
calibration trays before carrying out a full test.

9. Rotate the crank handle 103 turns. (For extra ac­curacy it is recommended to carry out a Calibra-
tions for Number of Turns, described on the next
page).

10. Weigh the seed collected from both trays in kilo­grams.Usean accurateset ofscales. Thisamount
is equivalent to 1/10th hectare.

Seeding Rate (kg/ha)=Weight Collected (kg) x 10

Variator to increase or decrease theseeding rate. Re­member to re-prime the feed mechanism with at least
50 turns before re-calibrating.

Note:Alwaysmovethe Variatorhandledownto zerothen
back up to the required setting.

Calibrations for Number of Turns

Asindicated at thestart of thissection, accuracy in calibra­tion can be affected by a number of factors not least of
which is soil type, wheel slip and sinkage. The number of
turns recommended for the calibration crank handle are
based on “average” figures in normal field conditions. If
farm conditions are very stony (so little sinkage) or very
sandy (so greater sinkage) then using the recommended
number of crank handle turns may be inaccurate.

To check the number of turns for individual field
conditions:

Refer to Figure 53

1. Shut down the shut-off slide aboveeach roller to pre­vent seeding.

2. Fill the drill half to two-thirds full of seed.

3. Mark out 167 meters of seedbed.

4. Position the calibration handle on the Variator input
and rotate to the upright (12 o’clock) position to givea
clear starting point.

5. Drive the distance marked-off in the seedbed and
count the number of turns the calibration handle
makes.

6. Note the number of turns and use this figure in the
Checkingthe Seeding Rate procedure inthe previous
section in place of the standard.

Hopper Clean-out

Refer to Figure 54

The seed hopper has two slide gates connected to dis­chargehoses forcleaning outthe bulkof theseed fromthe
hopper. Each slide gate is controlled by a handle that
extends out beyond the end of the meter assembly. The
discharge hose can be directed into a bag or into the
auger hopper.

Final meter clean-cut must be done using the calibration
trays. Slide the venturi units forward and place the calibra­tion trays under the feed rolls. Move the flap adjustment
handle to the full open position and empty the remaining
seed into the trays. The flap handle can be closed when
the trays are emptied.

Refer to Figure 55

The air distribution chamber must be inspected and keep
clean daily.

1. Remove end caps and visually inspect chamber.

2. To clean chamber, remove end caps and blow out
chamber with the fan.

Makesure thearea around theopenings is clear andthat
no one will enter the area before starting fan.

Tramlining

The meter can automatically leave tractor track marks or
“tramlines”in the correct position forsubsequent accurate
bout matching of spraying and fertilizing applications.

The system operates by stopping the drive to2+2feed
rollers (two in the left side of the hopper for the left track
mark and two in the right side of the hopper for the right
trackmark) asfactory fitted,these willgive atramline track
width of 3 times the drill row spacing.

Refer to Figure 56

Drive to the two feed rollers at the left end of each half of
themeter assembly is disengaged by arms attachedto an
electric actuator. These feed rollers are marked with trac­tor tread decals on the back of the meter assembly.

Drive is automatically engaged/disengaged in the
required sequence by the monitor control box positioned
in the cab. A magnet and sensor on the contact drive
record the bout count. See separate monitor instruction
section for further information and programming
instruction.

Setting up for Tramlines

The drill is set up to do “symmetrical tramlining” for 18m
(60ft) applicatorbooms, or “asymmetricalright tramlining”
for 12m (40 ft) and 24m (80 ft) applicator booms. See
Tramlining instructions in the Monitor section of this man­ual. With the optional NTA2000 dual tramlinecontrols kit,
(Great Plains P/N 890-785C) thedrill canbe setup for10
bouttramlining for 15m (50ft) applicator boomsor 18 bout
tramlining for 27m (90 ft) applicator booms.

Any seed hose can be connected to the tramline marked
feed rolls on the air distribution chamber. For symmetrical
tramlining, connect the right tramline marked feedrolls to
thedesired two rows right of center to leave amark for the
right sprayer track, and connect the left tramline marked
feed rolls to the desired two rows left of center to leave a
mark for the left sprayer track

Asymmetrical Right Tramlining

Asymmetrical right tramlining only requires the useof the
right tramline marked feed rolls. The actuator arm to the
left tramline marked feed rolls must be disconnected.

For asymmetrical right tramlining connect the right tram­line marked feed rolls to the desired two rows at the right
end of the drill to leave a mark for the sprayer tracks on
two consecutive passes.

Refer to Figure 57

Disconnect the actuator arm at the left side of the meter
assembly that operates the left feed roll tramline clutch.
This arm will have to be tied over to the right so the “star
shaped”teeth on thearm do notslide over andcontact the
feed roll clutch spring.

Note:Withthe optionalNTA2000dual tramlinecontrolskit,
(Great Plains P/N 890-785C) it will not be necessary to
disconnect the actuator arm.
