Hydraulic Hose Connections

NOTE: The SAE O-Ring and JIC 37˚ flare type hose
connections do not require sealant for reconnecting.
They do not require high torque for a good seal.

Uncoil the hoses from the first and the sixth frame sec­tionsand route them on the frame as showninFigure1-6.
The hoses from the rod end of the outer-most wing cylin­ders will connect to the elbows on the flow divider on the
center frame. The hoses from the base end of the wing
rear lift assist cylinders will attach to the rod end of the
master cylinders on the center section. Secure the hoses
to the frame with the 22”long cable ties provided. Avoid
routing the hoses where they could get pinched or worn
fromfolding,unfolding,raising, orloweringthe implement.
Do not let the hose rub on sharp edges and make sure
there is enough slack for down flex of the wing sections.

WARNING!

You may be severely injured or killed by being crushed between
the tractor and cart or between the cart and implement. Do not
stand or place any part of your body between the cart and im­plement while hooking up the implement.

Refer to Figure 1-10:

NOTE: When all connections have been made, care­fully check all lines to make sure none will be dam­aged when the implement is operated. Re-route the
lines or use cable ties to keep them in a safe place.

Bleeding the Hydraulic Lifting System

The implement lifting system is equipped with rephasing
type hydraulic cylinders that require a special procedure
forbleedingairfromthehydrauliccircuits. Readandfollow
the procedure carefully. The rephasing type cylinders will
not function properly with air in the hydraulic circuit. This
will cause uneven seeding depth across the implement.

WARNING!

Seriousinjury or deathcould resultfromescaping high pressure
hydraulicfluid. Use paper or cardboard,NOTBODY PARTS, to
check for suspected leaks.

WARNING!

Before attempting to hydraulically lift the implement, air drill
cart must be attached to the implement and to a tractor of suffi­cient size. Failure to do so could result in severe equipment
damage and bodily injury or death.

NOTE: Check the hydraulic fluid level in the tractor
reservoir and fill to the proper level. Add fluid to the
system as needed. A low reservoir level may draw air
back into the system and cause jerky or uneven cyl­inder movement. During initial cycling of new hydrau­lic cylinders, approximately8 3/4 gallons of oil will be
used to fill the new cylinders.

1. Make sure implement frame sections are supported

by jack stands or blocks.

2. With the frame blocked and supported, unpin the rod

endof the gauge wheel andlift assist wheel cylinders.
Pivot the cylinders up and wire or otherwise safely
support the rod end port higher than the base end
port, refer to Figure 1-11. The center dual gauge
wheel cylinders may have to be removed from the
frame so that they can be oriented with therod end
higher than the base end.

ed, hold the remote leveron for one minute.Check all
hydraulic hoses, cylinders, and fittings for leaks.

4. Retract the cylinder rods. Extend the rods again and
hold the remote leveron for one more minute. Repeat
this step two more times tocompletely bleed the sys­tem.Ifthe gauge wheel levelingadjustments aretobe
made, see Side to Side Frame Leveling, this section,
on page 19. Leave the cylinders unpinned and the im­plement frame supported. Again, check all hydraulic
hoses, cylinders, and fittings for leaks.

5. Recheck the tractor hydraulic reservoir and fill to the
proper level.

6. Repin all cylinders. Be sure implement is hooked to
cart and tractor. See Attaching the Cart to the Imple-
ment, this section, on page 16.

7. Slowlyextendcylinders until all cylinder rods are com­pletely extended.

8. Place cylinder lock channels on the front center dual
gauge wheel cylinder rods on both front dual gauge
wheels, see Figure 1-12.

Pre-Fold Coulter Settings

IMPORTANT: Failure to understand the following instruc­tions may result in equipment damage. Please read in­structions and perform the steps required before
attempting to fold the implement for the first time.

Ifyourimplement comes equipped with coulters, you must
make additional adjustments before folding your imple­ment for the first time. In order to ship yourimplement in a
more compact and efficient manner,the coulters were as­sembled in a raised position. This leaves the coulter
shanks extended far above the frame tube to which they
are mounted. If folding the implement is attempted while
the coulter shanks are extended in this manner, the top of
the shanks may bind at pivot points and equipment dam­age may result.

To avoid potential damage, coulters adjacent to fold pivot
pointsshould be adjusted so their shankextendsanallow­able distance above the frame tube (see coulter adjust­mentsinSection3ofyouroperator’smanual).Figure1-13
shows an example of an adjusted coulter.

Bleeding the Folding System

!

DANGER!

The folding cylinders must be bled free of air and implement
should be hooked to cart and tractor before attempting to fold
implement, otherwise severe property damage and bodily dam­age or death could result.

NOTE: Check the hydraulic fluid level in the tractor
reservoir and fill to the proper level. Add fluid to the
system as needed. A low reservoir level may draw air
back into the system and cause jerky or uneven cyl­inder movement. During initial cycling of new hydrau­lic cylinders, approximately 9.5 gallons of oil will be
used to fill the new cylinders.

1. Unpin the rod end of the fold cylinders and block up,
wire, or otherwise safely support the cylinders so that
when extended the rod end will not contact any ob­jects.

2. Cycle the cylinders completely in and out a minimum
of three times to purge all air from the fold system. In­spect all hoses, cylinders, and fittings for hydraulic oil
leaks.

ment. Periodic frame leveling should not be necessary.
You may, however, field check the levelness of the imple­ment by laying a straight edge across the top of at least
two members of a frame section and measuring the dis­tance from the bottom of the straight edge to the center of
the gauge wheel axle.By comparing this measurement to
the measurements taken from other frame sections and
gauge wheels, an indication of levelnesscan be obtained.
If levelingis necessary, follow the instructions listed.

Implement Frame Leveling

1. Thegauge wheel hydrauliccircuitshould be bledofair
and full of oil, see Bleeding the Hydraulic Lifting Sys-
tem, this section, page 16.

2. Hydraulically lower the entire implement frame. The
frame should then be jacked up and supported, see
Bleeding the Hydraulic Lifting System,this section,
page 16.

3. Retract the lift cylinders fully. Because the front dual
gaugewheelsonthe implement frames three and four
are non-adjustable, all adjustments will be made with
these as a reference.A referencemeasurement must
be taken by laying a straight edge across the top of at
leasttwotubes on the implement frame and takea ref­erence measurement from the bottom of the straight
edgeto the center of one dual gauge wheel axle, refer
to Figure 1-15.

WARNING!

Seriousinjury or deathcould resultfromescaping high pressure
hydraulicfluid. Use paper or cardboard,NOTBODY PARTS, to
check for suspected leaks.

3. Fullyextendthe cylinders torepinthe rod ends in their
respective slots.

NOTE:If cylinders on left or right side will not extend,
release the tractor hydraulic lever momentarily, re­verse the lever, and then tryagain. This switches the
sequence valve used to unfold one side at a time

Section 1 Assembly and Setup

NOTE: Towers must be located so that there is no in­terference when wings are folded or unfolded. After
towers have been installed and before any seed hos­es are installed, slowly fold the implement while
watching to be sure there are no interferences. Do
not stand under a wing while it is being folded or un­folded! If towers interfere with any other part of the
implement, completely unfold the implement and re­position the tower. Repeat these steps until imple­ment folds without tower interference.

2 1/2" Primary Distribution Hoses

Chooseimplementconfigurationtodetermine correct hose
routing.

1. Start with center tower(s). Route hose as shown in
Figure 1-21. Slide hose at least two inches onto tower
inlet (slide clamp over the end of hose first).

2. Allowenoughhose so that implementraising,lowering,
folding, and unfolding will not pinch or bind the hose.

3. Using a hacksaw, cut hose so that it will slide at least
twoinches on to meter outlet or up to end of outlet flare.

NOTE: Each tower should be connected to its corre­sponding outlet at the back of the cart. For example,
the center tower should be connected to the center
outlet on the meter box, the far right hand tower
should be connected to the far right hand outlet on
the meter box, etc.

4. When using double shoot towers, be sure to connect
thetower hoses totheappropriateoutletattheback of
thecart(refertohoseinstallationprocedure in the cart
manual). Slide clamp over hose end then slide hose
onto meter outlet. Install the clamp so it will not inter­fere with other hoses, clamps, or meter door latch
handles.

5. Repeat the above procedure on the remaining towers
working from the center towers toward the outside.

Section 2 Operating Instructions

General Description

This unit is a tillage-type seeding implement that can be
usedin both conventionalandno-till seeding applications.
It is designed to be used in conjunction with and towed be­hind a Great Plains air drill cart. Thecart supplies pneu­matically conveyed seed or fertilizer through five or ten
2 1/2” primary hoses. Each 2 1/2” hose is connected to a
distribution tower where the seed or fertilizer is evenlydis­tributedandcarried by air and gravitythrough a 1” second­ary hose to each opener or coulter. The implement frame
acceptstwotypes of openers: a floating hoeopener or a c­shank-style opener. The openers, configured in a 7” row
spacing,can be mounted across four ranks 28” apart.The
openerscan also beplacedona 7” rowspacingacross the
rear three ranks 28” apart thereby allowing the use of
coulters on the front rank. The coulters are placed so that
they run inbetween every two rows (14” apart). The
coulters are used to cut through residue and can be
equipped to apply dry fertilizer.

Seeding depth is controlled by front gauge wheel and
press wheel gang height. Coulter depth can be adjusted
individually.

The implement is equipped with an electricclutch switch to
stop and startmetering at the cartwhen the implement is
raised and lowered. The switch is adjustable so that the
height at which metering is stopped or started can be varied.

Prestart Checklist:

• Lubricate the implement as indicated in the Lubrication

portion of the “Maintenance and Lubrication” section
starting on page 39.

• Check all tires for proper inflation. See the Tire Inflation

Chart in the “Appendix” section on page 44.

• Perform all beginning of season and daily service items

discussed in the “Maintenance and Lubrication” sec­tion starting on page 39.

• Check the implement for worn or damaged parts and re-

pair or replace them before going to the field.

• All nuts, bolts, and screws should be checked. Refer to

the Torque Value Chart in the “Appendix” section on
page 44.

Recommended Tractor Size

NOTE: The tractor must be of adequate size to pull
the drill. When determining size of the tractor, soil
type, terrain, opener type, and tillage practices must
be considered.

Recommended Minimum Tractor Size

Standard openers and coulters - 240 HP
Double shoot openers - 300 HP

!

CAUTION!

The tractor or towing vehicle must have adequate unladen mass
to controlthe drill when towing. Do not exceed 20 miles per hour.

Minimum towing vehicle weight - loaded drill:

up to 20 mph maximum - 45,000 lbs.
up to 10 mph maximum - 22,000 lbs.

Minimum towing vehicle weight - empty drill:

up to 20 mph maximum - 28,000 lbs.
up to 10 mph maximum - 14,000 lbs.

NOTE: The tractor must have at least three sets of

Safety Lights

The light package your drill comes equipped with requires
that your tractor be wired for the standard 7-pin electrical
connector which will work with the tractor’s flashers and
signals.The harness from the air drill cart should be ready
to plug into the connector.

If your tractor is not equipped with this connector, please
consult your dealer for installation to the tractor manufac­turer’s specifications.

Field Operations

1. Be sure that all tires are properly inflated as indicated
in the Tire Inflation Chart in the “Appendix” section
on page 44.

2. Be sure that all hoses are connected and clear of for­eign material. Make sure openers are not plugged.

3. Neverback up with the openers in the ground. Do not
turn sharply with openers in the ground, doing so will
causeopeners to plug and couldcausedamagetothe
implement.

4. Make sure that nobody is in the way of the drill before
moving. Do not allow anyone to ride on the drill.

5. Follow all cart field operation instructions as found in
the cart operator’s manual.

6. Witha properly adjusted implement height switch,itis
not necessary to turn the electric clutch switchon and
off manually while turning. The clutch switch should
be turned off while transporting.

Implement Lifting System

The implement lifting system is equipped with rephasing­type hydraulic cylinders in a master-slave configuration.
Theymust be bledfreeofairusingtheprocedureslistedin

Bleeding the Hydraulic Lifting System inthe “Assembly
and Setup” section on page 16 for proper operation. The

cylindersmay,aftera period of time, get out of phase. This
will cause one section of the implement to run higher or
lower than other sections because the cylinders lifting it
areextendedmoreor less than the others.To rephase the
cylinders,raise the implement completely up and hold the
hydraulicleveronforseveralsecondsuntilallcylinders are
fully extended. This should be done every time the imple­ment is raised out of the ground. Once all cylinders are ful­ly extended, the hydraulic control should be momentarily
reversedtoallowthecylinderstoretract1/2”. This will help
maintain a level implement.

Fordepthcontrol,theimplement uses stopcollarsoneach
of the outside castor wheel cylinders, see Figure 2-1.
Along with the press wheel adjustments, the stopcollars
can be added and removed to adjust the seeding depth of
the openers. When not in use, the stop collars can be
stored on the hydraulic hose connected to the cylinders.

DANGER!

Electrocution hazard ­To prevent serious injury or death from electrocution: Keep
clear of overhead power lines when transporting, folding, un­folding, or operating all air drill components. Machine is not
grounded. Electrocution can occur without direct contact

1. Unfolding the drill is to be done on level ground only.
Be aware of the clearance required to unfold the drill.
Do not unfold the drill where it may come into contact
with any obstructions or overhead lines. Keep all by­standers clear awayfrom the area.

2. Remove folding lock pins and place them in the stor­age rings.

3. Set tractor at low idle speed.

4. Slowlyunfoldthe implement. During unfolding,one in­ner-framesection will unfold to approximately a 45 de­greeangle and stop. The outer frame section will then
fold out straight. Both frame sections will then unfold
until the outside gauge wheels support the two frame
sections. When one side has completely unfolded, re­lease and momentarily reverse the hydraulic lever.
Thiswillshift the spool in the sequencing valveso that
the other wing will unfold when the hydraulic lever is
again moved to unfold.

5. When the sections are unfolded, hold the lever until
the cylinders are completely extended to ensure that
wing flexibility will not be limited.

Opener Operation

General Opener Operation

1. Neverback up or turn sharply with openers in the
ground. Doing so will plug openersand may result in
equipment damage.

2. Check periodically for plugged openers and hoses.
With the fan running, manually operate the metering
system. Look below each opener for seed or fertilizer.
Do not crawl among the openers unless cylinder lock

channels are installed, the implement is sufficiently
blockedup, and the tractor is shut off with the key re­moved.

Forinformation on setting seed depth and making opener
adjustments, see Setting Seeding Depth and Leveling

Front-to-Rear in the “Adjustments” section on page 33.
C-Shank Style Opener

The C-shank style opener is designed to accept many dif­ferent hoe openers. The C-shank opener should provide
about 350 pounds of resistance at the hoe tip in the first
inch of travel. If the opener encounters an immovable ob­ject, the shank will trip back in order to travel over the ob­ject after which it will spring back to its normal operating
position.

!

DANGER!

The C-shank opener comes equipped with a pre-compressed
spring.Any attempt to removeor adjust the spring could release
the spring’s stored energy and could result in serious injury or
death.

Floating Hoe Opener

The floating hoe openers (shear bolt and spring reset)
bothhavean ability to “give”when theyencounter obstruc­tions. The spring reset hoe will trip when a large obstacle
is encountered. If the opener does not fully return to its
originalposition,liftthedrillout ofthegroundand allow the
spring to pull the opener back down.

For shear bolt openers, you must replace broken shear
bolts to reset the openers. Use 5/16” x 3”grade 5 bolts
only (Great Plains part number 802-131C).

Transporting

!

CAUTION!

This implement should never be towed faster than 20 miles per
hour.

Beforetransportingthe implement, checkandpracticethe
following items.

• When hitched to an air drill cart, the combined weight of

thisimplementandcartmustalwaysbekeptinmind.Be
sure that sufficient stopping distance is allowed at all
times and speed is reduced prior to making any turns or
other maneuvers.

• Besurethat the towingvehicleislarge enough tocontrol

the drill and implement on the road. Refer to Tractor Re­quirements, this section, on page 29.

• Know the maximum dimensions of the cart and imple-

ment in transport position and follow a route that pro­vides adequate clearance from all obstructions. Be
especially observant of low overhead power lines.

Coulter Adjustments

If your implement is equipped with optional coulters or
coulter fertilizer attachments, the following adjustments
can be made to optimize coulter performance.

Individual Coulter Depth Adjustments

Each coulter is independently mounted in front of and be­tween two openers. The coulters cut through residue
and/or cut grooves in the soil for fertilizer application. The
coulters are mounted on the front rank of the implement.
Therefore, the cutting depth of all the coulters on the im­plementwill change as the unit israisedandlowered, refer
to Setting Seeding Depth And Leveling Front to Rear on
page 33 for information on how to make this depth adjust­ment. The operator will want to adjust the coulters so that
they are operating at a relative depth to the openers.
Those coulters which run directly in implement, cart, or
tractor tire tracks mayneed to be adjusted differentlythan
the rest of the coulters. Coulter depth can beadjusted in­dependently of other coulters and openers by using the
following procedures.

!

WARNING!

Be sure cylinder lock channels are in place and wheels are
blockedto keep implement from rolling.Serious injury or death
could result from a falling or rolling implement.

Refer to Figure 3-8:

1. Besurethecoulterassemblyissupported by blocking
up the coulter.

2. Loosen the u-bolts holding the coulter clamp.

3. Slidecoulter shank up or down so thatthe coulter is at

Coulter Adjustments

Figure 3-8

NOTE:Many times the coulter depth will be adjusted
relative to the opener tip. The implement should be
parked on a clean, level area (preferably concrete)
when coulters are adjusted relative to the openers.

Coulter Spring Adjustments

No spring adjustment is necessary on this unit. Initial op­eratingforceto movecoulter upwards is 540 pounds.This
preload has provedto be more than adequate for most till­age conditions.

!

CAUTION!

Any attempt to make coulter force greater than factory setting,
may contribute to premature failureof parts and warranty shall
be null and void.

Fertilizer Tine Adjustments

Dry Fertilizer Tine Depth Adjustments

Refer to Figure 3-9:

When using the dry fertilizer attachment option with the
coulters, the bottom of the tine should run approximately
1”to1 1/2” below the surfaceofthesoil(thetine can be set
to run deeper but will cause excessive wear and will in­crease the chance of plugging). The tine should also be
settooperateapproximately1” behind the coulter blade in
a vertical or slightly back swept position. The main objec­tiveis to position the tine andfertilizeroutletinthevoidcre­atedas the coulter cuts throughthe soil. This will allowthe
nozzle to direct the fertilizer to the bottom of the trench be­forethe soil can fill backin. Set the fertilizer tine according
to the following procedures.

!

WARNING!

Be sure cylinder lock channels are in place and wheels are
blockedto keep implement from rolling.Serious injury or death
could result from a falling or rolling implement.

Section 3 Adjustments

The front to back setting of the fertilizertine can be
changed by loosening the two 5/8” carriagebolts (#1) that
hold the fertilizer tine arm (#2) to the main coulter arm
(#3). With the carriage bolts loose, the fertilizer tine arm
can be slid up and down the coulter arm.This will change
the distance from the rear of the coulter blade to the fertil­izertine (#4) and it will also change thefertilizer tine depth
(the tine should be approximate 1” from the rear of the
coulter blade). Keep in mind that the fertilizer tine should
remain in a vertical or slightly swept back position. A slot­ted hole (#5) in the fertilizer tine armcan be used to keep
the tine in proper orientation.

Once the horizontal distance from the coulter blade to the
fertilizertine is set, the verticalposition shouldbeadjusted
so that the tip of the tine will operate approximately 1” to 1
1/2” below the surface of the soil. This adjustment can be
made by removing the 1/2” bolt (#6) and spring tine clip
(#7) and moving the spring tine attachment to a higher or
lowerhole. Again, the slotted hole in the fertilizer tine arm
can be used to help make this adjustment.

Maintenance

General

Proper servicing and adjustment is the key to the long life of
anyfarmequipment. With careful and systematicinspection
and lubrication, you can avoid many costly repairs and
downtime.

Always turn off tractor and remove the key before making
any adjustments or performing maintenance.

Securely block raised implement before working under or
around it. Use cylinder channel locks on the gauge wheels
and fold lock pins on the wings.

Read and obey all safety labels on the implement.

1. After initially running the implement for several hours,
checkall bolts to be sure they are tight. Do not overtight­en the bolts holding the distribution tower assembly to­gether.

2. Lubricate the implement as noted in the Lubricationpor­tion of this section.

3. Always maintain correct pressures in tires.

4. Replace any worn, damaged or illegible safety labels at
once. New labels can be obtained from your Great
Plains dealer.

5. Any fittings which will not take grease must be cleaned
or replaced so that lubrication can be performed.

6. Periodically check and secure all bolts, pins, and
fasteners.

7. Occasionally inspect hydraulic hoses for cuts,
cracks, and aging. Check fittings and cylinders for
evidence of leaks.

8. Inspect cart link pins and bolts often for wear or
loosening of bolts.

Storage

Store the drill in an area where children do not play.

1. If you store the drill in the unfolded position, unpin
the fold cylinder rod ends and fully retract cylinders
to preventrust.

2. If the cart is disconnected from the implement for
storage, plug all 2 1/2” openings to prevent birds
from nesting in them.

3. Lubricate the drill at all points listed in this section.

4. Checkall bolts,pins,fittings,and hoses.Tighten,re­pair, or replace parts as needed.

5. Check all moving parts and soil contact parts for
wear or damage. Make notes of any parts needing
repair before the next drilling season.

6. Use Great Plains touch up paint to cover scratches,
chips, and worn areas to prevent rust.

7. Store the implement inside if possible to obtain a
longer implement life.
