Practice Safe Maintenance
Understand service procedure before doing work. Keep
area clean and dry.
Never lubricate, service, or adjust machine while it is
moving. Keep hands, feet , and clothing from power-driven
parts. Disengage all power and operate controls to relieve
pressure. Lower equipment to the ground. Stop the
engine. Remove the key. Allow machine to cool.
Securely support any machine elements that must be
raised for service work.
Keep all parts in good condition and properly installed.
Fix damage immediately. Replace worn or broken parts.
Remove any buildup of grease, oil, or debris.
On towed implements, disconnect wiring harnesses from
tractor before servicing electrical system components or
welding on machine.
TS218 —UN—23AUG88
On self-propelled equipment, disconnect battery ground

or welding on machine.
DX,SERV -19-17FEB99-1/1
Prevent falls by facing the machine when getting on and
off. Maintain 3-point contact with steps, handholds, and
handrails.
Use extra care when mud, snow, or moisture present
slippery conditions. Keep steps clean and free of grease
or oil. Never jump when exiting machine. Never mount or
dismount a moving machine.

Handle Electronic Components and Brackets
Safely
TS249 —UN—23AUG88
Falling while installing or removing electronic components
mounted on equipment can cause serious injury. Use a
ladder or platform to easily reach each mounting location.
Use sturdy and secure footholds and handholds. Do not
install or remove components in wet or icy conditions.
If installing or servicing a RTK base station on a tower or
other tall structure, use a certified climber.
If installing or servicing a global positioning receiver mast
used on an implement, use proper lifting techniques and
wear proper protective equipment. The mast is heavy and
can be awkward to handle. Two people are required when
mounting locations are not accessible from the ground
or from a service platform.

General Safety Instructions
Safety precautions:
• Always wear personal protective equipment.
• Use care when using tools.
• Lower implement on flat, solid ground when installing
brackets and harnesses.
CAUTION: When implement is lowered to
ground, tires may be free to spin. Do not stand
on tires while implement is in lowered position.
Failure to heed may result in serious injury.

• Harnesses should only be used on intended platforms
General Harness Instructions
and should NOT be modified in any way.
• Verify the wiring harnesses do not get pinched by
•
moving parts on the implement (Example: pinching may
occur on 3 pt hitch).
Tie-strap harness at least every 30 cm (12 in.) to
frame. Follow routing of existing harnesses as much
as possible.
IMPORTANT: Do not connect harnesses to tractor
during installation. Connecting power during
installation may result in damage to equipment.

General Harness Overview
The harness included in this kit is used to connect John
Deere™ GreenStar™ implement controllers (such
as the GreenStar 2 Rate Controller™ or implement
mounted StarFire™ receiver) into a single integrated
system. This installation allows flexibility based on
implement type. The harnesses required for each
system will vary based on the application, but every
system will require the following four components at
a minimum:
1. Master Switch and Constant Power Harness
This harness is used to extend the master switch and
constant power from inside the cab to the rear of the
tractor.
2. Front Extension Harness
Standard 3m and 10m Front Extension harnesses
are for implements that do not already have a CAN
controller installed. They connect into the ISO 9-pin
connector and the 3-pin Master Switch and Constant
Power harness connector at the rear of the tractor.
These harnesses typically run the length of the
drawbar to an Application harness (such as the main
GS2 Rate Controller harness or to an implement
mounted StarFire Receiver harness).
A separate type of front extension harness is available
for implements that are already equipped with a John
Deere controller (such as SeedStar™ planters).
3. Application Harness
Each application (such as GS2 Rate Controller or
implement mounted StarFire receiver) will have
an application harness that connects into the front
extension harness.
4. CAN Terminator Harness
The CAN Terminator harness is used to terminate the
CAN bus. It is applied on the last Application harness.
Some systems may also require the following components:
1. Center Extension Harness—extends Application and
Front Extension harnesses.
2. Rear Extension Harness—provides an ISO 9-pin
implement connector at the rear of an implement.
3. Switch and Power Extension Harness—extends the
3-pin connector on the Master Switch and Constant
Power harness.
4. Adapter Harness—provides connection from Main
GreenStar Rate Controller Application Harness to
specific implements.

Installation Overview
The high current power adapter harness is required when
valve/clutch current draw exceeds the 30 amps available
from the tractor ISO connector. It provides a secondary 2
pin connector at the rear of the tractor.

draw for some valves/clutches. View manufacturer’s
information for additional details.
When using multiple GreenStar Rate Controllers with a
large total number of sections, an additional source of high
current power to reliably control all of the valves and/or
clutches may be required. A key symptom indicating a
need for additional source of power would be frequently
blown fuses.

Each GreenStar Rate Controller must be connected to the
CAN though the 12 Pin connectors in series (G). GreenStar
Rate Controller 1 (A) will be using all of the available valve
power from the Tractor ISO Connector (E). GreenStar
Rate Controllers 2 (B) and 3 (C) are supplied power in a
second circuit by the High Current Power Adaptor Kit (D)
and Extension Harnesses (F). The total power required
on each circuit is less than the 30 amps available.
