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.
Be Familiar with Safety Decals
▲ Read and understand “Safety Decals” on page 6, thor-
oughly.
▲ Read all instructions noted on the decals.
▲ Keep decals clean. Replace damaged, faded and illegible
decals.
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.

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 the drill.
195-069M Table of Contents Index 2014-02-03
Great Plains Manufacturing, Inc. Table of Contents Index Important Safety Information 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 when fold-
ing/unfolding, raising/lowering markers, raising/lowering
openers, and transporting.
Transport Machinery Safely
Maximum transport speed for drill 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 (32 kph). Never travel at a speed
which does not allow adequate control of steering and stopping. Reduce speed if towed load is not equipped with
brakes.
▲ Comply with national, regional and local laws.
▲ Follow your tractor manual recommendations for maximum
hitch loads. Insufficient weight on tractor steering wheels
will result in loss of control.
▲ Carry reflectors or flags to mark drill in case of breakdown
on the road.
▲ Keep clear of overhead power lines and other obstructions
when transporting. Refer to transport dimensions under
“Specifications and Capacities” on page 104.
Check for Overhead Lines
Drill markers contacting overhead electrical lines can
introduce lethal voltage levels on drill and tractor frames.
A person touching almost any metal part can complete
the circuit to ground, resulting in serious injury or death.
At higher voltages, electrocution can occur without direct
contact.
▲ Avoid overhead lines during seed loading/unloading and
marker operations.

Description of Unit
The 2S-2600HD is a towed seeding implement. This two
section drill has a working width of 26 feet (8m). The drill
has straight arm, double disk heavy duty openers. The
opener disks make a seed bed, and seed tubes mounted
between the disks place seed in the furrow. Press
wheels following the opener disks close the furrow and
gauge opener seeding depth. A T-handle on the opener
body is for seeding depth adjustments. Seeding rates are
adjustable with the seed rate adjustment handle and
sprocket changes.
The 2S-2600HD features active hydraulic down pressure
on the opener frames. When used on a tractor with
closed-center hydraulics, constant down pressure
ensures even opener penetration in uneven ground.
Hydraulic down pressure is adjustable at a single point.
Intended Usage
Use this implement to seed production-agriculture crops
in conventional or minimum tillage applications.

Preparation and Setup
This section helps you prepare your tractor and drill for
use. Before using the drill in the field, you must hitch the
drill to a suitable tractor and also setup the drill.
Pre-Setup Checklist
1. Read and understand “Important Safety Information” on page 1.
2. Check that all working parts are moving freely, bolts
are tight, and cotter pins are spread.
3. Check that all grease fittings are in place and lubricated. See “Lubrication” on page 91.
4. Check that all safety decals and reflectors are correctly located and legible. Replace if damaged. See
“Safety Decals” on page 6.
5. Inflate tires to pressure recommended and tighten
wheel bolts as specified. “Appendix A” on page 104.
Hitching
Crushing Hazard:
You may be severely injured or killed by being crushed
between the tractor and drill. Do not stand or place any part of
your body between machines being hitched. Stop tractor
engine and set park brake before installing hitch pins.
Transport Hazard:
This drill can have positive and negative tongue weight, which
can work the hitch pin loose during transport. To avoid serious
injury or death due to a road accident, always use a clevis
hitch or clevis drawbar with a locking-style hitch pin.
Choose a drill-hitch option (page 99) that is compatible
with your tractor drawbar.
The 2S-2600HD has three hitch options:
• a clevis hitch,
• a small-hole, single-strap hitch or;
• a large-hole, single-strap hitch.
Use the clevis hitch with tractors that have single-tang
drawbars. Use the single-strap hitch for tractors with clevis drawbars. Always use a locking-style hitch pin sized
to match the holes in the hitch and drawbar.
195-069M Table of Contents Index 2014-02-03
Great Plains Manufacturing, Inc. Table of Contents Index Preparation and Setup 15
Refer to Figure 4 and Figure 5
To adjust the drill hitch to match your tractor-drawbar
height, mount tongue jack on side of tongue. Use jack to
raise drill tongue so lowest hitch hole is 18 inches
(45.7cm) above ground level with drill lowered to FIELD
position.
Refer to Figure 5
Bolt drill hitch onto drill tongue to match your tractor-drawbar height. You can turn the hitch over for a total
of six different hitch heights. Always have two (2) bolts in
two holes of both tongue and hitch.
Note: When hitching drill to a different tractor, check for a
difference in drawbar heights. If heights are different, readjust hitch height accordingly.
Securely attach safety chain to an anchor on a tractor

Hydraulic Hose Hookup
High Pressure Fluid Hazard:
Only trained personnel should work on system hydraulics!
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin, causing serious injury. Avoid the hazard by
relieving pressure before disconnecting hydraulic lines. Use a
piece of paper or cardboard, NOT BODY PARTS, to check for
leaks. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems. If an accident occurs,
seek immediate medical attention from a physician familiar
with this type of injury.

Setting the Bypass Valve
1
Refer to Figure 12
A bypass valve is plumbed into the opener down pressure circuit. Tractors with load-sensing, closed-center
hydraulics require this bypass valve to protect the tractor
hydraulic system. If you are unsure what type of hydraulic system is on your tractor, contact your tractor manufacturer.
“CENTER” are the two inside opener lift cylinders.
“WING” are the two outside opener lift cylinders.
If the Point Row option is installed, these controls are
re-plumbed as entire “LEFT” and “RIGHT” wings.

Tractors with Open Center Hydraulics
Release locking disc. Close bypass valve for no oil flow
by turning knob on valve clockwise completely. Tighten
locking disc. Always operate the drill with the bypass
valve locked closed.
Tractors with Pressure Compensating Closed Center Hydraulics (PC Closed)
Release locking disc. Close bypass valve for no oil flow
by turning knob clockwise completely. Tighten locking
disc. Always operate the drill with the bypass valve
locked closed.
Tractors with Load Sensing Closed Center Hydraulics (LS Closed) or Pressure Flow Compensating (PFC) Systems
1. Release locking disc. Initially close bypass valve for
no oil flow by turning knob on valve clockwise completely.
2. With tractor at half throttle, adjust flow-control valve
on tractor so openers raise and lower at a reasonable speed. Keep tractor at one-half throttle for
remaining steps.
Note: The faster openers raise and lower, the greater po-
tential for oil heating, premature wear or tractor
damage.
3. Engage tractor hydraulics and lower openers. Lock
hydraulic lever on tractor for continuous operation.
See “Raising and Lowering Openers” on page 24.

4. Release locking discs on down-pressure valves.
Adjust knobs on pressure-control valves for
opener down pressure so gauges are at 1500 psi.
5. While watching gauges on drill, slowly turn knob on
bypass valve counterclockwise. Adjust bypass valve
just until needles on gauges begin to move down
from 1500 psi. Lock bypass valve at this setting.
(See also note below.)
6. Re-adjust pressure-control valves on drill to desired
opener down pressure as explained under See
“Opener Frame Down-Force” on page 62.
Note: The higher the bypass pressure, the greater the po-
tential for oil heating and premature tractor damage. At the same time, for proper opener operation
the bypass valve must be set at least 100 psi above
the opener down-pressure setting when the tractor
is at one-half throttle. Therefore, you should set the
bypass valve as low as possible while staying at
least 100 psi above the opener down pressure setting.
While 1500 psi is a good starting point for setting the
bypass valve, if you consistently operate the drill with low
opener down pressure you can set the bypass valve
below 2100 psi. If you consistently operate the drill with
very high opener down pressure, you may need a
bypass-valve setting above 2100 psi. See also
“Opener-Subframe Adjustment” on page 64.

Adjusting the Counter Balance Valve
On the stem of the valve there is a rubber cap that protects the threads of an adjustment stem. This stem is
locked in place with a hex nut. To adjust the valve, loosen
the nut and turn the stem using an Allen wrench.
Screwing the stem in (clockwise) pushes on a spring
which supplements the pilot line’s force on an internal
piston. More spring force will let the valve open with a
low pilot pressure. Less spring force will require higher
pilot pressure to open the valve.
Note: With the screw turned in fully, the spring will
develop enough force on the piston to unlock the
valve, even with no pilot pressure, causing the
openers to settle.
Raise and lower the drill several times then hold hydraulic down pressure on the openers to purge air from the
system and to warm the oil. Repeat.
Raise the openers. Observe the openers closely to detect
settling. If the openers remain up, no valve adjustment is
needed.
If the openers settle, the stem is screwed in too far. Gently
back the stem out until it stops, then screw it in one turn.
Generally this is a good starting point. Check for settling.
Backing the stem out will lock the valve, screwing it in too
far can cause it to unlock.
A small increase in lowering speed can be achieved by
screwing the stem in.

Marker Setup
Refer to Figure 14
Markers are field-installed, but usually do not have their
extension length precisely set. The drill must be lev-
eled per “Leveling the Drill” on page 84, and marker(s)
must be in correct working order per “Marker Mainte-
nance” on page 87.
Row unit centerline stations on 2S-2600HD drills are
symmetrical about machine center, so left and right
extensions are normally identical, for both opposing and
concentric passes.
Set the initial length of the marker(s) as follows:
1. With drill unfolded, lower drill and openers to field
position (“Raising and Lowering Openers” on page
24).
2. Extend a marker on one side. Pull forward several
feet to leave a mark.
3. Sighting parallel to the main tool bar, measure
from the centerline of the left outside row unit to the
mark.
4. Adjust the marker extension so that the mark is
one half the span plus one row unit spacing .
See “Marker Adjustments” on page 70 for setting
marker extension.
5. Pull forward several feet, and re-measure to verify
any adjustment. Validate the mark by making a pass
to one or both sides.
6. Fold marker. Extend other side and adjust.

Operating Instructions
This section covers general operating procedures. It
assumes that setup items have been completed for both
drill and tractor.
Experience, machine familiarity and the following information will lead to efficient operation and good working
habits. Always operate farm machinery with safety in
mind.
General Description
On the standard 2S-2600HD, field operations are controlled by tractor cab hydraulic levers. When openers are
lowered, mechanical clutches engage, and the gauge
wheels drive the seed meter shafts. Markers, if installed,
are on a separate circuit.
If the Point Row Option is installed, openers are controlled by section (wing), and are raised and lowered by
solenoid valves operated by the point row controller.
Both Transport Lift and Opener Lift circuits must be in the
raised configuration for folding and unfolding.
Seed meters operate at a rate proportional to ground
speed, as set by Drive Type and Seed Rate Handles,
based on the Seed Rate charts, and calibration.
Seeding depth and furrow coverage are controlled by drill
down pressure and row unit setup.

Pre-Start Checklist
❑ Lubricate the drill as indicated under Lubrication,
“Maintenance and Lubrication” on page 78.
❑ Check the tires for proper inflation according to “Tire
Inflation Chart” on page 104.
❑ Check for worn or damaged parts and repair or
replace before going to the field.
❑ Check all nuts, bolts and screws. Tighten bolts as
specified on “Torque Values Chart” on page 105
Raising and Lowering Openers
Opener sub-frames are on a dedicated hydraulic circuit.
Openers raise and lower independently of the drill frame
(which is raised and lowered by the Transport Lift circuit).
When lowered, the opener circuit can use live hydraulic
power to regulate down pressure. To operate with live
power, connect the opener lift circuit to the #1 remote
hydraulic circuit or the circuit designed for HYDRAULIC
MOTOR control. On many CLOSED CENTER or PRESSURE/FLOW COMPENSATED tractors the #1 circuit is
designed to supply live hydraulic power to remotes.
On the standard 2S-2600HD drill, the openers raise and
lower as a group, from a tractor cab lever. If the Point
Row Option is installed, each section can raise and lower
independently, using switches on the point row control
module in the tractor cab.
If the Two Outlet conversion kit is installed, a selector
valve near the hitch must be operated to switch between
Opener Lift and Transport Lift. During field operations,
this valve is in the Opener Lift position.
Opener Lock Up
The openers must be raised and locked up for folding,
transporting or for working under the drill.
Negative Tongue Weight: Raising openers on unfolded,
unhitched drill will cause drill tongue to rise suddenly, which
could cause serious injury or death. Be certain that drill is
hitched securely to your tractor drawbar and the safety chain
is securely attached to tractor before raising openers and
unfolding drill.

Refer to Figure 18
1. Position opener transport lock handles in FIELD
position.
2. Raise openers completely, to release locks.
3. Lower openers.
Machine Damage Risk:
Never lower openers with drill folded.
Raising Drill (Transport Lift)
Transport Lift is on a dedicated hydraulic circuit. The
center main frame raises and lowers independently of
the opener sub-frames (which are raised and lowered by
the Opener Lift circuit).
Transport Lift is normally used prior to folding and during
rate calibrations. Opener Lift, and not Transport Lift, is
used for headland turns in field operations.
Swing-up channels are used to lock the lift cylinders in
the raised (extended) configuration, preventing settling
during transport, parking, calibrations, servicing and
storage.
Refer to Figure 22
Note: Wings flex down before gauge wheels are lifted off
the ground during transport lift.
Transport Lift
1. Raise the openers. See “Raising and Lowering
Openers” on page 24.
2. If the Two Outlet conversion kit is installed, a selector
valve near the hitch must be operated to switch
between Transport Lift and Opener Lift. See “Lift
Selector Valve Operation” on page 42.
3. Supply oil to the base (extend) ends of the Transport
Lift cylinders.

4. Swing the locks up and onto the transport lift cylinders. They are temporarily held in place with polymer
bumpers. They are firmly held in place when the cylinder is relaxed in step 5.
Note: Bumpers hold the transport lift cylinder lock chan-
nels in place temporarily. The channels will remain
in position when cylinders settle against channels.
5. Slowly reverse the Transport Lift circuit lever until
both lock channels are resting firmly on the rod ends
of the transport lift cylinders. Set circuit lever to off.

Folding
Crushing Hazard:
Bystanders could be crushed between the folding drill boxes
and the drill tongue. To avoid serious injury or death, keep all
bystanders well away during folding operation.
1. Park tractor and drill on level ground with tractor
transmission in Park. Be aware of clearance needed
to fold drill.
2. Fold up markers if installed. See “Marker Opera-
tion” on page 41. Return selector valve handle to
Fold position.
Refer to Figure 24
3. Raise openers. Opener subframe must be raised for
folding. Position all six opener lock handles in ROAD
position and completely raise openers. See “Raising
and Lowering Openers” on page 24.
Note: The opener transport lock handles are spring load-
ed and can be moved to ROAD position with openers up or down, but locks only engage when
openers are completely raised. There are two locks
on each drill section.
4. Raise drill, engage lift lock channels and allow drill to
settle on lock channels. See “Raising Drill (Trans-
port Lift)” on page 25.
Note: During transport lift, wings flex down before lifting
off ground.
Machine Damage Risk:
Both Opener and Transport Lift circuits must be raised and
locked up before folding, or implement damage will result.
