Important Safety Information
For your safety, thoroughly read Important Safety
Information in the operator’s manuals before proceeding.
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.
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 27.

2019-04-25 Table of Contents 195-201Q
2S-2600 and 2S-2600F Table of Contents 2
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.
Avoid overhead lines during seed loading/unloading and
marker operations.
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, see a doctor immediately. Any fluid
injected into the skin must be surgically removed within a
few hours or gangrene may result.
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.
Put tractor in park, turn off engine, and remove key before
performing maintenance.
Make sure all moving parts have stopped and all system
pressure is relieved.
Disconnect battery ground cable (-) before servicing or
adjusting electrical systems or before welding on drill.
Inspect all parts. Make sure parts are in good condition
and installed properly.
Remove buildup of grease, oil or debris.
Remove all tools and unused parts from drill before
operation.
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 for you to stand to one side–not in front
of or over tire assembly. Use a safety cage if available.
When removing and installing wheels, use wheel-handling
equipment adequate for weight involved.

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.
Safety Decals
Safety Reflectors and Decals
Your implement comes equipped with all lights, safety
reflectors and decals in place. They were designed to
help you safely operate your implement.
Read and follow decal directions.
Keep lights in operating condition.

195-200P 2S-2600 Parts Manual
195-325B Seed Rate Manual
Description of Unit
The 2S-2600 is a towed seeding implement. This
two-section drill has a working width of 26 feet and folds
to a transport width of 15 feet. The drill has straight-arm,
double-disk 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 the sprocket box.
The 2S-2600 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.
The 2S-2600F allows you to plant seed and apply
fertilizer in the same field pass. Dividers partition the drill
boxes into seed and fertilizer compartments. The
openers apply dry fertilizer to the seed trench before the
furrow is closed. You also can use both compartments for
seed.
Intended Usage
Use this implement to seed production-agriculture crops
in conventional-tillage applications. Do not modify the
drill for use with attachments other than Great Plains
options and accessories specified for use with the
2S-2600 Drill.

are installed after hookup, bleeding and leveling. See
“Install Final Accessories” on page 24.
Two Outlet Kit
If the two-outlet hydraulic kit was ordered, install it now
(before the markers, as this kit contains items needed
when both 2-outlet and markers are installed).
Installation instructions are provided in a separate
manual with the two-outlet hydraulic kit.

Point Row Option
If the point row option was ordered with the drill, the
hydraulics and drill electrical lead are factory-installed.
If the customer’s primary tractor is available, install the
control module in the tractor cable and make the electrical
connection. Consult the point row installation manual
provided.
If the primary tractor is not available, temporarily connect
the control module so that openers can be operated
during Setup.
Post Assembly Checklist
Check that all working parts are moving freely, bolts
are tight, and cotter pins are spread.
Check for proper tension and alignment on all drive

Setup
The Assembly steps of the preceding chapter must be
completed prior to setup.
Setup steps consist of:
1. Hitch to suitable tractor.
2. Connect hydraulics.
3. Bleed hydraulics.
4. Level drill.
5. Install any accessories and options not
factory-installed, which can or must be deferred until
after first unfolding.
Hitching
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.
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 that is compatible with your
tractor drawbar.
Refer to Figure 14
The 2S-2600 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.

Refer to Figure 15 and Figure 16
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 16
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
capable of pulling the drill.
Refer to Figure 17
Use crank to raise jack foot. Remove pin and jack. Store
jack on top of tongue.

Hydraulic Hose Hookup
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,
see a doctor immediately. Any fluid injected into the skin must
be surgically removed within a few hours or gangrene will
result.
Refer to Figure 20
Great Plains hydraulic hoses are color coded handle
grips to help you hookup hoses to your tractor outlets.
Hoses that go to the same remote valve are marked with
the same color.
Current Style Color Coded Hose Handles
To distinguish hoses on the same hydraulic circuit, refer
to the symbol molded into the handle grip. Hoses with
an extended-cylinder symbol feed cylinder base ends.
Hoses with a retracted-cylinder symbol feed cylinder rod
ends.
1. Connect opener-lift hoses to circuit designated for
hydraulic-motor control.
2. Connect transport-lift hoses to tractor remote valve.
3. Connect fold hoses to tractor remote valve.
4. Connect marker hoses to tractor remote valve.
NOTE:
If your tractor has only two remote valves, you must
install a double-selector valve to combine the
transport-lift and opener-lift circuits. See “Two Outlet
Kit” on page 11.
Hydraulic Operations
Consult the Operator’s Manual for unfolding and lowering
instructions. Pay strict attention to the step ordering.
Both Opener and Transport Lift circuits must be raised and
locked up before folding, or implement damage will result.

To run drill on tractors with open-center hydraulics or on
tractors with fixed-displacement hydraulic pumps, you must
install a Great Plains kit, part number 194-143A. If you are
not familiar with your tractor hydraulics, consult your tractor
dealer.
