Assembly Instructions & Set Up
Before You Start
Read and understand the operator’s manual for
your drill. A basic understanding of how the drill
works will aid in the assembly and setup of your
drill.
Before attempting to assemble the drill use the following as a check list. Having all the needed parts
and equipment readily at hand will speed up your
assembly task and will make the job as safe as
possible.
Check for all major frame components
!
CAUTION
Be familiar with the term NEGATIVE TONGUE
WEIGHT. Be aware of the special precautions you
should take when working with an implement that can
develop Negative Tongue Weight.
Have a minimum of twopeople on hand while
assembling the drill.
Check for fasteners and pins that were
shipped with the drill.
Note: All hardware coming from the factory has
been installed in the location where it will be used.
If a part or fastener is temporarily removed for assembly reasons, remember where it goes. Keep
the parts separated.
If a pin, bolt or other part has been removed
and you are unsure where it is used, use the parts
manual for this drill to identify it. Be sure the part
gets used in the correct location.By double checking while you assemble, you will lessen the
chance of using a bolt incorrectly that may be
needed later.
Have a forklift or loader along with chains
and safety stands that are sized for the job ready
for the assembly task.
Have a tractor with remote hydraulics ready
to attach to the tongue. The tongue must be anchored to a large enough tractor to overcome the
negative tongue weight that will be present when
the boxes are attached to the frame. The hydraulics will aid in raising and lowering the drill to align
pins and bolts during assembly.

Assembling The Drill
Refer to Figure 1 on page 15
1. Read and understand the previous section
Before You Start.
2. Read "Practice Safe Maintenance," page 4,
before assembling drill.
3. Set the tongue (1) approximately 21" off the
ground in a horizontal position with stable
blocking for support.
4. Raise the mainframe (2) up, keeping the side
members horizontal. Position the mainframe
(2) over the tongue (1) and lower into position.
5. Secure tongue (1) to main frame (2) with six
1" x 2 1/2" long bolts (3), lock washers and
nuts.
6. Attach the tongue screw jack (4) in a vertical
position and remove blocking so the unit is on
the ground.
7. Remove the safety wires from each hydraulic
cylinder rod clevis between the tires.
8. Slide the hydraulic hoses from the mainframe
through the tongue and pull them out at the
tractor end. Attach tractor male couplers to
the hydraulic hoses.
9. Hook tractor up to the tongue and plug hydraulic connectors into the tractor. With tractor running at an idle speed charge the drill
hydraulic system. (Be sure your tractor has
plenty of hydraulic fluid. This system requires
approximately 3.3 gallons.) When your drill
frame raises for the first time, one lift cylinder
will extend fully before the other one begins to
move. Once the first cylinder is fully extended
continue to hold yourtractor valve in the same
position for at least 60 seconds after the second lift cylinder has fully extended. The reason for the unevenness of raising for the first
time is because your drill is equipped with
master and slave rephasing cylinders. Raise
and lower the frame several times to be sure
there is no binding or problems with your lift
system. Refer to "Tractor Hydraulic Hookup,"
page 18, for additional information.
10. Attach the gauge-wheel turnbuckle (5) to the
gauge-wheel arm (6) on each drill and then
mount the wheel (7) and tire.
11. Position the two drill boxes in line, end to end,
with the end chain drive sprockets outboard
and approximately 3" between the drill boxes.
Drills on 8" row spacing and narrower will
have 8" spacing at disks between boxes.
12. Using the tractor, back the drill main frame up
to the center of the two drill boxes (8). When
close, position the posts (9) on each side of
the main frame so the face of the post mounting angles are toward the drill frames. Attach
the post (9) to the drill frames (8) using eight
5/8 x 3 1/2 x 5" long U-bolts (10), lockwashers
(11) and nuts (12). With the U-bolts (10) left
loose, slide the drill frames (8) inward so that
the lugs (13) welded to the drill frames are up
tight against the post angles. Tighten all the
nuts on the U-bolts.
13. Attach frame adjustment link (14) from the
drill frame to the pivot post using the clevis pin
(15) with hairpin cotters. Pin to pin should be
approximately 37".
14. Locate drill transport stabilizer frame (16)
against the locator stop on the box frame. Using 5/8" U-bolts (17), lock washers (18) and
nuts (19), mount stabilizer to box frame.
15. Adjust clevis end of pull bars (20) so that the
distance from the center line to center line of
pull bar pin holes is approximately 134 1/4".
16. Mount pull bars to drill transport stabilizer
frames (16) and tongue slide (21). With the
tongue slide in the back position against its
stop, adjust pull bar lengths so boxes are in
line with one another and parallel to the back
edge of the mainframe.
17. Extend the main lift cylinder (22) and place
the transport lock pins (23) in the transport
position through the holes in the mainframe
axle side tube.
18. Fold the drill making sure that the tongue slide
(21) moves smoothly up the tongue. When
drill boxes are almost folding in, stop and adjust the post-frame adjustment links on each
box so that the tang (24) on each drill transport stabilizer frame lines up with the nest (25)
on the front of the main frame. Fold drill completely closed.
19. With tongue slide (21) forward on the tongue
and drill folded completely, position the pull
bar lock pin (26) across the top of the tongue
slide. Adjust the transport lock bolt (27) on top

and front of tongue up against lock pin with
1/16" clearance and lock the jam nut. This pin
prevents the drill from unfolding when in
transport.
Do not lower drill while in folded position.
20. Check to see that all nuts are tightened. See
the "Torque Values Chart," page 36, for
torque specifications.

Tractor Requirements
Great Plains 2-Section Folding Drills are engineered to be used with tractors having a standard
drawbar.
To operate your Great Plains Folding Drill in most
field conditions, a tractor of 125 minimum horsepower for 24’ drills and 150 minimum horsepower
for 30’ drills should be used.
Tractor Draw Bar Hookup
Refer to Figure 2, 3 and 4

1. 1.The hitch can be used as either a single
strap, clevis or combination hitch as shown in
Figure 2 Single Strap Hitch, Figure 3 Clevis
Hitch and Figure 4 Combination Hitch.
!
CAUTION
This drill has both positive and negative tongue
weight. Never unhook from tractor with boxes Unfolded and Raised off the ground.
2. When using the combination hitch, remove
lower strap when hooking up to a clevis-type
tractor drawbar. Spacers between the drawbar and hitch may be added to eliminate
some of the movement of the tongue caused
from positive to negative tongue weight.
Two hitch sizes are available: The small hole hitch
with or without the hammer strap (1 1/4" maximum pin diameter) and the large hole hitch
without a hammer strap (up to 1 1/2" diameter
pin). The small-hole hitch is sold as standard
equipment.
The mounting holes in the hitch have been offset
so the hitch can be turned over and bolted on in
three different positions giving you six different
hitch heights. On the clevis-type hitch, always
mount the thinner strap on the bottom.

Note: Set hitch so tongue of drill is parallel to
ground when drill is in planting position. Use
tongue jack to level tongue, then find closest setting of hitch to match your tractor drawbar height.
3. Attach safety chain on tongue hitch to tractor
and lock hook securely on chain. Adjust chain
length to remove all slack except what is necessary to permit turning of the drill and tractor.
4. The tongue jack makes it possible to raise or
lower the hitch for tractor unhooking and reconnecting. Always return jack to its horizontal position on top of the tongue at the pull bar
slide stop.
Tractor Hydraulic Hookup
For ease of operation, your tractor should be
equipped with six remote hydraulic outlets (three
pairs). This will allow you to connect one pair to
the drill lift circuit, one pair to your drill fold circuit
and one pair remaining for connection of optional
markers. If your tractor has only four remote outlets (two pairs) and a marker circuit is required, a
marker sequences valve with double selector is
available through your Great Plains dealer.
Hydraulic Hose Hookup
Refer to Figure 5
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.

WARNING
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
medical assistance from a doctor that is familiar with
this type of injury. Foreign fluids in the tissue must be
surgically removed within a few hours or gangrene
will result.

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.
IMPORTANT: When using sealant on pipe
threads the friction between the threads is reduced; therefore, be certain not to over tighten, causing damage to a valve, cylinder port or
fitting.
!
CAUTION
This drill has a negative tongue weight when unfolded
and raised. Be certain that the drill is hitched securely
to your tractor draw bar and be certain the hitch safety
chain is securely attached to the drill hitch and tractor
before raising or unfolding the drill!
Bleeding the Lifting Hydraulic System
This Folding Drill is equipped with rephasing type
hydraulic lift cylinders that require a special procedure for bleeding air from the hydraulic system. If
your dealer has not already prepared the cylinders for transport use, read the following
information carefully. The rephasing cylinders will
not function properly if this bleeding procedure is
not followed. Do not crack hose fittings in order to
bleed air from this system.
screw the adjustment screw in until it bottoms.
Lower the drill until the cylinders become
loose.
2. Unpin the cylinders from the mainframe and
turn the cylinders upside down to a position
where the rod end is higher than the base end.
Support the cylinders in a safe location. One
transport tire may have to be removed in order
to unpin the master cylinder.
3. Start the tractor and run the engine at idle.
With the rod end of the cylinders higher than
the base end, hydraulically extend the cylinders and hold the tractor control lever in position for sixty seconds after the cylinders have
extended to their maximum stroke.
4. Hydraulically retract the cylinders, then repeat
the extending procedure several more times
until both cylinders are free of air and operate
together.
5. Repin the cylinders to themain frameand axle
with the rod end down. If air is tapped in either
cylinder, the affected cylinder will have a
spongy, erratic movement and the machine
will not raise evenly. Refill the tractor hydraulic
fluid reservoir to its proper level.
NOTE: After drill is raised, a slight settling will occur due to the action of the rephasing cylinder
NOTE: Check the hydraulic fluid level in the tractor reservoir and fill to the proper level before
starting this procedure. If the bleeding is performed with a low reservoir supply, there is a
chance of drawing air into the system. System capacity is approximately 3.3 gallons and requires
one pair of remote outlets.
1. If required, raise your drill 1" in order to extend
your lift cylinders a little. Loosen the jam nuts
on top of the transport vertical tubes and
8/17/2006
NOTE: In order to prevent trapped air pockets,
the port on the rod end must be higher than
any other port of the cylinder during the bleeding operation.
NOTE: The folding and transport wing lift cylinders
are not rephasing type cylinders and do not require this bleeding procedure.

Bleeding Hydraulics (Cont.)
!
The following section describes a bleeding procedure
that requires you to crack (loosen) a hydraulic fitting.
Be aware that these lines may be under pressure even
with the tractor shut off. Never allow anyone under the
drill when a fitting is opened. Escaping fluid may allow
the drill to suddenly drop. Be aware of the following
medical alert.
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
medical assistance from a doctor that is familiar with
this type of injury. Foreign fluids in the tissue must be
surgically removed within a few hours or gangrene
will result.
DANGER
!
WARNING
Bleeding Folding Hydraulics
Note: The drill transport lift systems should be
completely operational before attempting to work
with the folding hydraulic circuit.
Note: The cylinders are double acting but are not
the rephasing type.
1. The first step in charging the fold hydraulic circuit is to make sure the tractor hydraulic fluid
reservoir is filled to the proper level. System
capacity is approximately 2 gallons and requires one pair of remote outlets. If optional
selector is used, rotate to the wing lift position.
2. With the drill fully raised and in the folded position, disconnect the rod end pin on each fold
cylinder and block the cylinders in a location
where they are free to extend and retract without contacting anything.
3. Cycle the fold cylinders in and out several
times to work the air out of the system.
Refer to Figure 6
Figure 6
Wing Fold Hydraulics
4. Retract the hydraulic cylinder and repin the
rod ends.
5. Recheck the tractor reservoir level and add
clean fluid as necessary.
6. It is advisable to fold and unfold the drill several times. The majority of the air should now be
expelled from this system. The remaining air
will gradually be pushed to the tractor during
day to day operations.
Note: If the wing fold cylinders do not operate
properly, clean out the small hole in the elbow fitting on fold cylinders. These orifice are located in
the cylinder elbow as circled.

Leveling the Drill
Note: This section describes procedures for leveling the drill on its initial setup. This should be a
one-time adjustment and will not be needed during day-to-day operation. If while using the drill, it
appears to be lifting or planting uneven, check the
following before re-leveling the drill. First, make
sure the tongue is running level to the ground
while running in the field. Be sure to check this if
the drill has been switched to a different tractor.
See "Tractor Draw Bar Hook-Up," page 17. Second, check the lift cylinders. Be sure they are
properly bled, are operating correctly, and do not
have internal oil leaks before using this section to
re-level the drill.
Refer to Figure 7
The opener spring rods located along the back of
the drill boxes are indicators of the level of the drill
because they show the amount of down-pressure
exerted on the disk openers and press wheels. A
level drill will have equal opener down-pressure
from end to end. Check the spring rod cross bolts
at the top of the spring rods to see that they are all
extended about 2 inches above their spring rod
castings, . This is a general dimension and may
vary with the spring down-pressure you require
for different soil conditions and planting depths
(See “Press Wheel Depth Adjustments,” page
28). If you require more downward float of your
openers you may want to increase this dimension.
Keep in mind when this dimension is increased
your upward motion is decreased, limiting the vertical travel of the openers for running over rocks
and other foreign objects.
Figure 7
Opener Spring Rods
Leveling the Drill
10548

!
CAUTION
If your openers’ vertical travel is decreased, considerable damage will occur to your openers.
If all the spring rods along the drill extend the
same distance above their castings, the drill is level and you should tighten down the threaded
studs as described in "Transport Wheel Adjustments for Leveling," page 22. If the spring-rod
extensions vary in length, the drill can be leveled
with transport wheel and gauge wheel adjustments. These are described on page 22.
To summarize: After leveling your drill, it should
have the same dimension from the ground to the
box frame at both ends of each box. These adjustments may have to be fined tuned after observing
the drill in the field in actual planting conditions.

Transport Wheel Adjustments For Leveling Drill
When leveling your drill, opener spring rods near the
center of the drill that extend higher above their
spring rod castings than desired can be adjusted by
raising the transport frame. This is done by raising
the drill with the hydraulic lift cylinders. Spring rods
near the center that do not extend high enough are
adjusted by lowering the transport frame by retracting the cylinders.
Refer to Figure 8
Once the spring rods are at the desired setting,
screw the threaded studs on top of the vertical tubes
down as far as possible and secure them with the
jam nuts. This adjustment will stop the lift cylinder
travel at the same point each time the boxes are
lowered for drilling and assures accurate seed
depth control.
Note: If it is noticed that one drill box spring rod extension is different from the other drill box at the
center of your drill, this is a sign that your lift hydraulic master and slave cylinders are out of sequence
with one another. In order to get them back in sequence, simply raise your drill all the way up and
hold your tractor hydraulic control valve lever on for
a few seconds. Now, lower your drill and both cylinders will be in sequence with one another and your
two drill boxes should be at the same level again.
Jam Nut

Gauge Wheel Adjustments For Leveling Drill
The openers near the outside of the drill are adjusted by raising or lowering the gauge wheels.
Refer to Figure 9
Raise the drill out of the ground and loosen the jam
nut located near the bottom clevis of the gauge
wheel turnbuckle. This turnbuckle is threaded to allow easy gauge wheel adjustment. By lengthening
the turnbuckle the gauge wheel is lowered, causing
less spring rod extension through the spring rod
casting. By shortening the turnbuckle the gauge
wheel is raised, causing less spring rod to protrude
through the spring rod casting. After adjusting, be
sure the turnbuckle on both gauge wheel arms have
the same pin center dimension.
Shortening the gauge wheel turnbuckle will level the
ends of the drill with the center.

LIfting
The lift cylinders may after a period of time get out
of time or phase. The effects of this can be seen
when one side of the drill is running too low or too
high because its lift cylinder is either overextended or not retracted compared to the other lift
cylinders.
To rephase the cylinders, raise the drill completely
up and hold the tractor hydraulic lever on for a few
seconds to give the cylinders time to rephase.
This should be done each time the drill is raised
out of the ground. Momentarily reversing the hydraulic lever immediately after rephasing to allow
the cylinders to retract about 1/2" will help in maintaining a level drill.
Note: Understand that having the cylinders become gradually out of time is different than having
air trapped in the system from improper bleeding.
Each condition is corrected differently.

Adjustments
Press Wheel Opener Linkage Depth
Adjustment
Attached to the rear of each opener is one of several optional press wheels. The press wheel and
its mechanism provide two important functions:
1. The press wheel closes the furrow and gently
presses the soil over the seed.
To provide consistent seed firming, the press
wheel is free to move downward from its normal
operating position. This system maintains pressing action even if the opener body is lifted as a
result of the opener disks encountering an obstruction or hard soil.
2. The press wheel rolls on the ground providing
depth control to the opener and seed.To
maintain a consistent planting depth, the relationship between the bottom of the opener
disk-blades and the press wheel is upwardly
fixed. The upward stop is independently adjustable on each opener. The position of the
adjustable stop determines how deep the
seed will be placed.
12100
Figure 23
Direct Link Press Wheel Adjustment
Refer to Figure 23
To change the height of the press wheel, which
automatically changes the seeding depth of the
opener, simply lift the "T" handle located on top of
the opener at the rear and slide forward or rearward until the seeding depth is correct as shown
in the inset in . A spring loaded pin holds the "T"
handle at your setting to maintain the proper
depth.
Disk Opener Spring Pressure Setting
Refer to Figure 24
Each opener spring can be adjusted for down
pressure. This is useful when penetrating hard
soil and for planting in tractor tire tracks. To adjust
the pressure, remove the "W" clip at the bottom of
the spring and place it in a higher hole in the
spring rod for more pressure, and in a lower hole
for less pressure.

General Notes for Field Operations
Most of the procedures described in this section
require the useof a tractor with hydraulic remotes.
Before proceeding with the first time setup, or before making any adjustments mentioned in this
section, make every effort to obtain and hitch a
tractor to the drill.
24’ DRILL minimum of 125 horsepower
30’ DRILL minimum of 150 horsepower
1. Be certain that the drill tires have the proper
inflation as listed in the "Tire Inflation Chart,"
page 36.
2. Load seed box with seed. Use clean seed to
get the best results. Always have the drill
hitched securely to a tractor with safety chain
connected. Lower the drill before loading.
3. This drill can be transported with a full box of
grain. It is best not to do this unless necessary
because the increased weight does increase
the chances for problems on the road. Do not
exceed 20 miles per hour.
4. Calibrate each seed box for a proper rate
based on the seed that you are drilling. Calibration information is located on the inside of
your box lid or under "Seeding Adjustments,"
in the seed rate book. Make sure the seed
rate is adjusted the same across the entire
drill.
5. If your drill comes equipped with an acremeter, it should be mounted on the left gauge
wheel axle on the outboard side. It will accumulate the total acres drilled with the drill. In
order to find out the acres covered, write
down the beginning reading and subtract it
from the ending reading for the total acres
planted.
to a wider setting.
9. Never back up with openers in ground. If you
do, check all openers to be sure none are
clogged.
10. After lowering the drill into planting position,
observe the drill from the side. Check to see
that the tongue is level to the ground. If it is
not, a hitch height adjustment is needed. See
"Tractor Draw Bar Hookup," page 17. It is especially important to check for this if the drill
has been hitched to a different tractor.
11. This drill is not designed to be turned sharply
in the field. Always lift the drill completely out
of the ground when turning at ends of field
rows and other short-radius turns. If the drill is
not completely raised, the lift hydraulics will
be out of sequence. Refer to "Bleeding Hydraulics," page 19.
12. Never allow anyone to ride on the drill.
13. Maximum seeding speed will vary according
to soil conditions.
14. You can adjust the tension on each disk
spring. This is especially useful in applying
more pressure in tractor tire tracks.
15. Never unhook drill from tractor with
!
boxes unfolded and raised off the ground.
Negative tongue weight is present in this position.
16. Never attempt to lower the drill while in
!
folded position.
6. This drill is offered in different row spacings;
therefore, some of the drill boxes do not have
the same number of seed cups between each
internal box divider. The section with the largest number of cups will tend to empty sooner.
7. Make sure that the seed-cup-dooradjustment
handles are set the same across the drill.
8. If you notice excessive cracking on largegrain seeds, adjust all seed cup door handles

bar. Inspect the chain and hardware for wear
or other damage. Replace immediately if
needed.
6. After a period of time, the drill boxes may
gradually become out of line with each other.
To correct this condition, refer to " Box Alignment Adjustments," page 23.
3. Listed below are the items you need to lubricate before storing the drill:
a. Clean and oil all roller chains.
b. Seed cup drive sprocket should be oiled
in its square bore. Move seed cup adjustment lever away from the sprocket as far
as possible in order to get the oil back into
the square.
c. Oil knob adjustment trunnion lower pivot
tube on press wheels.
Note: Proper servicing and adjustment is the key
to the long life of any farm implement. With careful
and systematic inspection, you can avoid costly
maintenance, time and repair.
Storage
1. Clean the drill as necessary. Be sure that the
seed boxes, fertilizer box and all feed systems
are completely cleaned out before storing.
2. Lube chain and adjust all roller chains.
Lubrication
1. After using your drill for several hours, check

Spring pressure on openers could be improperly adjusted causing
opener to not penetrate low spots.
Check for trash or mud build-up on Seed-Lok Wheel.
Check to see if scraper is adjusted too tightly and is restricting disk
movement.
Check disk bearings.
Check opener frame for possible damage.
If opener disks turn freely by hand but not in field, reduce down pressure on disk opener.
Check press wheel adjustment for seeding depth.
Check tire pressure. Proper inflation is listed in "Tire Inflation Chart,’
page 36.
Check gauge wheel size. Proper size is 9.5L x 15.
Seed treatment will affect seeding rate if the chemicals build up in
seed cup. Unless cleaned regularly, this build up can cause breakage
of the seed-cup shaft.
Check speed change box setting.
See "Seeding Adjustments," located in the seed rate book, for
instructions on calculating seed rate.
Excessive seed cracking Use slower drive speed and open flutes in seed cup to a wider posi-
tion.

Re-adjust press wheel depth to match coulter depth.
Increase down pressure on disk openers.
Grain box not emptying evenly Certain models do not have the same number of seed cups
between each divider of bulkhead. The section with the larger
number of cups will empty sooner.
Seed cups close to the ends of box tend to empty sooner due to
amount of seed available.
Check adjustment levers on each box to see that they are set on
the same indicator number.
Press wheel or openers plugging Drilling in damp or wet conditions may increase this problem.
Openers may be moved from a staggered to an in-line position
to reduce trash thrown from front openers into rear openers.
Reduce down pressure on openers.
Do not back up drill in the field, or stop and allow drill to roll
backwards with openers in the ground.
If using double "V" press wheels, adjust angle bar.
Check Seed-Lok Wheel.
Rubber tire depth control wheels
becoming packed with mud.
Install scrapers.
Reduce spring tension on openers.
Improper folding of drills Adjust post frame adjusting links.
Check hydraulic system for air and oil leaks.
Clean out small orifice fittings in wing cylinders.
Make sure that the wing boxes unfold to a straight line. Check
to see that both pull bars are attached to the boxes at exactly
the same distance inboard from the inboard edge of the drill
box {90"} and both are exactly the same length.
Hydraulic adaptors cracking JIC fittings do not require high torque.
Always use liquid pipe sealant when adding or replacing pipe
thread hydraulic fittings. Plastic sealant tape can crack fittings
and plug hydraulic lines. JIC and O-Ring fittings do not require
sealant. O-Ring fittings require a thin coat of oil on the O-Ring.
Important: When using sealant on pipe threads, the friction
between the threads is reduced; therefore, be certain not to
overtighten causing damage to the cylinders, valves or fittings.

Problem Solution
Seed-cup sprockets locked up or
twisted seed-drive shaft
Raising and lowering drill is rough
and uneven
Hydraulic marker functioning improperly
Check for foreign matter lodged in one or more seed cup
sprockets.
Liquid insecticide from seed has dried within the seed cup.
Remove the build up by disassembling each seed cup and
scrape the foreign substance from the turning surfaces. Note:
Liquid inoculant should be applied with caution and care
should be taken to clean the seeding system after drilling
treated seeds.
Lubricate lower rollers of vertical transport tubes located
between the transport tires.
Check hydraulic fittings for leaks.
Rephasing cylinders not properly bled. See "Bleeding Hydraulics," page 19. When raising drill at end of field, the lifting cylinders should be fully extended to ensure that they are always
rephased. If machine is only raised enough to lift openers out of
the ground, lift cylinders may eventually get out of sequence
and cause uneven seeding depth.
Check all hose fittings and connections for air and oil leaks.
The chain on the folding 3-section marker should be slack when
the marker is both fully extended and fully raised.
Check tractor hydraulic oil level.
Check all bolts and fasteners.
Double selector valve positioned for wing fold. Shift valve to
marker sequence position.
Open needle valve, cycle markers slowly and reset needle valve
if plugged.
Chain-debris/retainer clip Be sure retainer clip open end is facing opposite way of chain
travel.
