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.
1
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.
000

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.
08/03/2010 160-269M-A
2 CTA4000
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.
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.
Handle Chemicals Properly
Agricultural chemicals can be dangerous. Improper use
can seriously injure persons, animals, plants, soil and
property.
▲ Do not use liquid treatments with implement.
▲ Read and follow chemical manufacturer’s instructions.
▲ Wear protective clothing.
▲ Handle all chemicals with care.
▲ Avoid inhaling smoke from any type of chemical fire.
▲ Never drain, rinse or wash dispensers within 100 feet (30m)
of a freshwater source, nor at a car wash.
▲ Store or dispose of unused chemicals as specified by chemi-
cal manufacturer.
▲ Dispose of empty chemical containers properly. Laws gen-
erally require power rinsing or rinsing three times, followed
by perforation of the container to prevent re-use.
160-269M-A 08/03/2010
Check for Overhead Lines
Seed auger or implement markers contacting overhead
electrical lines can introduce lethal voltage levels on
implement, cart 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.
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 implement and cart.
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 folding/
unfolding, raising/lowering markers, raising/lowering
openers, and transporting.
Transport Machinery Safely
Maximum transport speed for implement 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.
A
▲ Carry reflectors or flags to mark implement and cart 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 55.
08/03/2010 160-269M-A

Shutdown and Storage
▲ Clean out and safely store or dispose of residual chemicals.
▲ Secure implement using blocks and transport locks. Lower
openers if not locked up.
▲ Store in an area where children normally do not play.
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 implement.
▲ Inspect all parts. Make sure parts are in good condition and
installed properly.
OFF
▲ Remove buildup of grease, oil or debris.
▲ Remove all tools and unused parts from implement 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.
160-269M-A 08/03/2010
Safety At All Times
Thoroughly read and understand the instructions in this
manual before operation. Read all instructions noted on
the safety decals.
▲ Be familiar with all cart and implement functions.
▲ Operate machinery from the driver’s seat only.
▲ Do not leave implement unattended with tractor engine
running.
▲ Do not dismount a moving tractor. Dismounting a moving
tractor could cause serious injury or death.
▲ Do not stand between the tractor and implement during
hitching.

Preparation and Setup
This section helps you prepare your tractor, cart and
implement for use. Before using the implement in the
field, you must hitch the implement to a suitable tractor,
compatible cart, and also setup the implement.
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 51.
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” on page 55.
Hitching
You may be severely injured or killed by being crushed
between the tractor, cart and implement. 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.
When ready for planting, the implement is part of an
assembly that includes the tractor, the cart, and the
implement.
When hitching for the first time, hitch the leading cart to
the tractor first.
Once the cart is hitched to the implement, it is usually left
connected, unless parking or storage considerations
require separation.
This manual includes full details only for the implement’s
hitch. Consult the cart manual for cart-to-tractor hitching.
If the tractor has a load-sensing or constant-flow hydraulic
system, the implement must be equipped with an optional
bypass valve to avoid tractor damage. See “Hydraulic Bypass
Kit” on page 53 for ordering. See “Bleeding Hydraulics” on
page 15 for setup.

Make Hydraulic Connections
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.

160-269M-A 08/03/2010
Hydraulic Circuit Connections
The implement has one or two hydraulic circuits (with a
low pressure sump return line). The standard circuit powers lift, fold and weight-transfer functions, controlled by a
valve block on the left front of the implement. An optional
circuit operates the markers.
Great Plains hydraulic hoses are color coded to help you
hookup hoses to your cart outlets. Hoses that go to the
same remote valve are marked with the same color.
Preparation and Setup 15
If the tractor has a load-sensing or constant-flow hydraulic
system, the implement must be equipped with an optional
bypass valve to avoid tractor damage. See “Hydraulic Bypass
Kit” on page 53 for ordering.
1. Shut down tractor hydraulics.
2. If optional markers are already installed, connect
marker hoses to receptacles and per instruc-

6. Check hose routing to ensure adequate slack for link
arm movement, and clearance from pinching or
abrading cart/implement components.
Bleeding Hydraulics
To function properly, the hydraulics must be free of air. If
hydraulics have not been bled, they will operate with
jerky, uneven motions and could cause wings to drop
rapidly during folding or unfolding. During initial implement setup (which may have been done by your dealer)
or if you replace a hydraulic component, complete the
