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 self-propelled equipment, disconnect battery ground 

cable (-) before making adjustments on electrical systems 

or welding on machine. 

On towed implements, disconnect wiring harnesses from 

tractor before servicing electrical system components or 

welding on machine. 

Handle Electronic Components and Brackets 

Safely 

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.

Operate Guidance Systems Safely 

Do not use guidance systems on roadways. Always turn 

off (disable) guidance systems before entering a roadway. 

Do not attempt to turn on (activate) a guidance system 

while transporting on a roadway. 

Guidance systems are intended to aid the operator in 

performing field operations more efficiently. The operator 

is always responsible for the machine path. Guidance 

systems do not automatically detect or prevent collisions 

with obstacles or other machines. 

Guidance Systems include any application that automates 

vehicle steering. This includes, but may not be limited 

to, AutoTrac, iGuide, iTEC Pro, ATU, RowSense, and 

Machine Sync. 

To prevent injury to the operator and bystanders: 

• Never get on or off a moving vehicle. 

Use Seat Belt Properly 

Use a seat belt when you operate with a roll-over 

protective structure (ROPS) or cab to minimize chance of 

injury from an accident such as an overturn. 

Do not use a seat belt if operating without a ROPS or cab. 

Replace entire seat belt if mounting hardware, buckle, 

belt, or retractor show signs of damage. 

Inspect seat belt and mounting hardware at least 

once a year. Look for signs of loose hardware or belt 

damage, such as cuts, fraying, extreme or unusual wear, 

discoloration, or abrasion. Replace only with replacement 

parts approved for your machine. See your John Deere 

dealer. 

Safety 

Use AutoTrac Controller on Approved Vehicles 

Use AutoTrac Controller only on Approved Vehicles—see 

StellarSupport.Deere.com for list of approved vehicles. 

When activity monitor is selected, AutoTrac Controller 

looks for operator activity every seven minutes. Operator 

05-3 

• Verify the machine, implement, and guidance system 

are set up correctly. 

- If using iTEC Pro, verify accurate boundaries have 

been defined. 

- If using Machine Sync, verify the follower’s home 

point is calibrated with sufficient space between the 

vehicles. 

• Remain alert and pay attention to the surrounding 

environment. 

• Take control of the steering wheel, when necessary, to 

avoid field hazards, bystanders, equipment, or other 

obstacles. 

• Stop operation if poor visibility conditions impair your 

ability to operate the machine or identify people or 

obstacles in the machine path. 

• Consider field conditions, visibility, and vehicle 

configuration when selecting vehicle speed.

AutoTrac Accuracy 


IMPORTANT: The AutoTrac system relies on the GPS 

system operated by the government of the 

United States, which is solely responsible for 

its accuracy and maintenance. The system is 

subject to changes that could affect accuracy 

and performance of all GPS equipment. 

The overall AutoTrac system accuracy is dependent upon 

many variables. The equation looks like: 

AutoTrac System Accuracy = Signal accuracy + Vehicle 

Setup + Implement Setup + Field/Soil Conditions. 

It is very important to remember: 

• Receiver has to go through a warm-up period after 

starting. 

• Vehicle is setup properly (ballasted according to vehicle 

operator manual, etc.) 

General Information 

All operators must be familiar with AutoTrac system and 

operating characteristics prior to operation. The following 

is a suggested procedure for operator to become familiar 

with system: 

1. Read and understand Operators Manual for GreenStar 

Guidance—Parallel Tracking and AutoTrac Assisted 

Steering Systems. 

2. Choose an open area free of hazards (ditches, 

buildings, etc.). 

3. Set Track Spacing to 92.0 meters (300 ft). 

4. Set a Track 0 (A—B Line). 

NOTE: Operate vehicle at a speed you are comfortable, 

recommend less than 8 km/h (5 mph). 

5. Enable AutoTrac on display by turning Steer ON. 

6. Press Resume switch to activate AutoTrac. (See 

Activating system later in this section). 

7. After driving a short distance, then turn steering wheel 

to turn vehicle off track to deactivate AutoTrac. (See 

Deactivating System later in this section). 

8. Practice Activating AutoTrac at different distances 

before and after crossing track and at different angles. 

Increase and decrease speeds to simulate different 

operating conditions. 

9. Reduce Track Spacing to acquire multiple tracks and 

continue practicing activating AutoTrac at different 

angles and varying speeds to understand how 

AutoTrac behaves under different conditions. 

15-1 

• Implement is setup to run properly (wear parts such 

as shanks, shovels, and sweeps are in good working 

condition and correctly spaced). 

• Understand how field/soil conditions affect system 

(loose soil requires more steering than firm soil, but firm 

soil can cause uneven draft loads). 

See the AUTOTRAC SYSTEM ACCURACY section 

in DIAGNOSTICS section of this manual for more 

information. 

IMPORTANT: Although AutoTrac system can be 

activated when SF2 (or SF1 if using AutoTrac 

SF1 activation) correction signal is confirmed, 

system accuracy may continue to increase 

after powering up system. 

AutoTrac SF2 activation will operate on a SF1, SF2, or 

RTK signal. 

AutoTrac SF1 activation will operate on a SF1 signal only. 

JS56696,0000614 -19-15JUN09-1/1 

Always be prepared to resume manual control if AutoTrac 

does not perform expected maneuvers or machine course 

must be changed to avoid injury or property damage. 

Operator can regain manual steering by turning steering 

wheel or Disabling AutoTrac by turning Steer off on 

display. It is recommended practice to be as close as 

possible to desired track prior to activating AutoTrac. This 

will ensure correct track and direction are acquired. 

The AutoTrac basic system is intended to be used as 

an assistance tool to mechanical markers on planters. 

Operator must evaluate overall system accuracy to 

determine specific field operations where assisted 

steering may be used. This evaluation is necessary 

because accuracy required for various field operations 

may differ depending on farming operation. Because 

AutoTrac uses StarFire differential correction network 

along with Global Positioning System (GPS), slight shifts 

in position may occur over time. 

To operate AutoTrac operator must set track 0 (similar to 

parallel tracking) and all tracks are drawn parallel to track 

0 using track spacing. 

The AutoTrac system operating status can exist at four 

levels: INSTALLED, CONFIGURED, ENABLED, and 

ACTIVATED. 

After enabling AutoTrac (see Enabling AutoTrac), 

AutoTrac is activated by pressing resume switch 

on armrest (see Activating AutoTrac). To return to 

manual steering, operator must deactivate system (see 

Deactivating System). 

If required track can be shifted left, right or centered using 

shift track feature on display. (See Shift Track).

AutoTrac Setup 

Operate Guidance Systems Safely 

Read and understand Operate Guidance Systems Safely 

in the Safety section. 

AutoTrac System 

General Information 

IMPORTANT: 

AutoTrac system relies on GPS system operated 

by the United States government, which is solely 

responsible for its accuracy and maintenance. 

System is subject to changes that could affect 

accuracy and performance of all GPS equipment. 

Operator must maintain responsibility for 

machine and must turn at end of each track. 

This system will not turn at end of a track 

unless equipped with iTEC Pro. 

AutoTrac basic system is intended to be used as an 

assistance tool to mechanical markers. Operator must 

evaluate overall system accuracy to determine specific 

field operations where assisted steering may be used. This 

evaluation is necessary because accuracy required for 

various field operations may differ depending on farming 

operation. Because AutoTrac uses STARFIRE differential 

correction network along with Global Positioning System 

(GPS), slight shifts in position may occur over time. 

AutoTrac Accuracy—The overall AutoTrac system 

accuracy is dependent upon many variables. The 

equation looks like: 

AutoTrac System Accuracy = Signal accuracy + Vehicle 

Setup + Implement Setup + Field/Soil Conditions. 


25-3 

It is very important to remember: 

• Receiver has to go through a warm-up period after 

starting. 

• Vehicle is setup properly (ballasted according to vehicle 

operator manual, etc.) 

• Implement is setup to run properly (wear parts such 

as shanks, shovels, and sweeps are in good working 

condition and correctly spaced). 

• Understand how field/soil conditions affect system 

(loose soil requires more steering than firm soil, but firm 

soil can cause uneven draft loads). 

Status Pie 

IMPORTANT: Although AutoTrac system can be 

activated when SF2 (or SF1 if using AutoTrac 

SF1 activation) correction signal is confirmed, 

system accuracy may continue to increase 

after powering up system. 

AutoTrac SF2 activation will operate on 

SF1, SF2, or RTK signal. 

AutoTrac SF1 activation will operate on 

SF1 signal only. 

NOTE: The status pie and steer icon will not be displayed 

if no SSU or AutoTrac Activation is detected.

Steering Sensitivity 

To adjust steering sensitivity select the input box and enter 

the desired steering sensitivity value via numeric keypad 

and select the enter button. The sensitivity can also be 

adjusted up or down by selecting the + or – buttons on 

either side of the steer sensitivity input box. 

NOTE: Valid range for steer sensitivity is 50-200 with 

200 being the most aggressive setting. 

User Adjustable Steering Sensitivity—steering 

sensitivity is aggressiveness of AutoTrac steering system. 

A high steering sensitivity setting is more aggressive to 

allow system to handle tough manual steering conditions

Steer Sensitivity 

such as integral implements with a heavy draft load. A 

low steering sensitivity setting is less aggressive to allow 

system to handle lighter draft loads and higher speeds. 

Figure B 

A—Default Gain B—Entered Steering Gain C—Track D—2.5 seconds 

The steering sensitivity is only applied after machine 

is within 0.5 M (1.6 ft) of track FIGURE A. Therefore, 

adjusting steering sensitivity does not change line 

acquisition performance. 

The steering sensitivity is momentarily reduced if tractor 

front wheel and heading oscillations become too large. 

25-5 

BA31779,00003B8 -19-29FEB12-7/22 

This event may be observed when implement is raised at 

start or end of row transitions. If this event is observed 

while implement is activated, sensitivity level is too high 

(see Steering Sensitivity). 


PC8849 —UN—30OCT05 

031312 

PN=31

Adjusting Steering Sensitivity Level 

The steering sensitivity must be adjusted to accommodate 

field conditions and tractor/implement configuration. 

Steering sensitivity should always be evaluated when 

implement is activated. In general, soft soil requires a 

higher steering sensitivity level than firm ground and an 

Figure A 


A—10 second B—1 second C—Track 

Too Low—If steering sensitivity is too low, a slow 

wandering track error pattern can be observed on display. 

This track error pattern takes approximately 10 seconds to 

go from side to side as is shown in FIGURE A. If excessive 

track error is occurring, increase steering sensitivity by 

small increments until desired accuracy is achieved. 

NOTE: It is normal to see a momentary track error when 

encountering a large rut, furrow, or implement load 

change. Proper steering sensitivity adjustment 

will help minimize track error. 

Too High—Setting steering sensitivity to highest level 

will not result in maximum tracking accuracy. If steering 

sensitivity is too high, excessive front wheel motion 

will be observed which reduces accuracy and causes 

unnecessary front axle component wear. At extreme 

high levels, machine motion will become large enough to 

cause steering sensitivity to be momentarily changed to 

default level. Wheel motion to watch for when determining 

if aggressiveness is too high occurs at an interval of 

approximately 1 second from side to side as shown in 

FIGURE B. If excessive wheel motion is observed, lower 

steering sensitivity by small increments until desired 

performance is achieved. 

Optimizing AutoTrac Controller Performance 

When operating in curves, start with the curve sensitivity 

equal to the optimized acquire sensitivity. 

These default settings are a good starting point for most 

conditions. Each setting can be adjusted to try and 

optimize performance. Operator may need to readjust 

line sensitivity, heading, and line sensitivity tracking for 

best results. Increase or decrease settings to change 

aggressiveness as desired. If system is not responsive 

enough, increase sensitivity settings. If desired 

PC8850 —UN—30OCT05 

25-6 

integral implement requires a higher steering sensitivity 

than a similar drawn implement. Finally, steering 

sensitivity will not address condition where front wheels 

are not able to turn tractor. Always make sure front axle 

load with implement activated is sufficient for steering 

before adjusting steering sensitivity level.

performance is not achieved, see TROUBLESHOOTING 

section for more detail. 

Advanced AutoTrac Settings 

Tuning Recommendations 

NOTE: AutoTrac Controller has been tuned to perform 

very well in most field conditions using the 

variety of implements encountered by AutoTrac. 

However, for those conditions outside of normal, 

we have provided Advanced Settings to allow 

the operator fine tune their systems for specific 

field conditions and implements. 

Problem or Situation: 

AutoTrac performance during line acquisitions, Curve Trac 

or in-row S-ing that can’t be tuned out using the Steering 

Sensitivity adjustment. 

Difficult ground conditions (extremely soft or extremely 

rough) require additional tuning beyond the capabilities of 

the standard Steering Sensitivity value. 

Read this information in it’s entirety BEFORE tuning 

AutoTrac Advanced Settings. 

AutoTrac Advanced Settings software includes 6 different 

tunable sensitivities that allow finer adjustment of the 

AutoTrac system. The following are details for tuning 

this software: 

1. Check & fix other problems before you 

tune—Perform necessary mechanical checks and 

calibrations through associated tractor. It is important 

to do this step first otherwise you run the risk of 


PC8851 —UN—30OCT05 

031312 

PN=32

masking actual machine faults and wasting your time 

tuning a system that cannot be tuned. 

2. Characterize the current AutoTrac problem—There 

are various types of issues this software may be able 

to resolve. First, the specific type of problem needs to 

be identified from the possible items below: 

a. Excessive Wheel Motion—Overall AutoTrac 

performance is acceptable, but the operator is 

concerned about how quickly the wheels are 

twitching back and forth. 

b. Aggressive S-ing Motion—Continual back and 

forth motion as observed by the operator looking 

out over the front nose of the tractor. Although a lot 

of motion is observed, the off-track error shown on 

the display (distance away from AB line) is often 

relatively small. 

c. Lazy S-ing Motion—Performance of AutoTrac 

seems very sluggish when trying to stay on the line 

and slowly wanders from side to side. 

d. Lazy Line Acquisition—AutoTrac appears 

sluggish during line acquisition and the tractor 

remains off to one side of the line for a long time 

before getting lined up. 

e. Aggressive Line Acquisition—AutoTrac 

overshoots the line, and continues to 

overcompensate during acquisition. Results in high 

frequency, tight S-ing pattern during acquisitions. 

f. Lazy Curve Track Performance—AutoTrac is 

sluggish in Curve Track mode resulting in slow, 

wandering S-ing about the desired line and often 

tracks to the outside of the desired path. 

g. Aggressive Curve Track Performance—AutoTrac 

exhibits rapid and high frequency corrections in 

Curve Track mode, resulting in a tight S-ing pattern 

or tracking to the inside of the desired path. 

3. Access the Advanced Settings page on GS3. 

4. Advanced Settings Parameters. 

a. Line Sensitivity Heading: Determines how 

aggressively AutoTrac responds to heading error. 

Higher Settings: Result in more aggressive 

response to vehicle heading error. 

Lower settings: Result in less aggressive response 

to vehicle heading error. 

Range: 50 to 200. 

b. Line Sensitivity Tracking (Lateral Gain): 

Determines how aggressively AutoTrac responds 

to off-track (lateral) error. 

Higher settings: Result in more aggressive 

response to vehicle off-track error. 


25-7 


to vehicle off-track error. 

Range: 50 to 200. 

c. Heading Lead: Determines the impact of yaw 

rate (vehicle rate of turn) on tracking performance. 

Heading lead acts as a look-ahead parameter and 

can be used to minimize over steering. Large 

adjustments may result in poor performance. 

Higher settings: Result in more aggressive 

response to yaw rate. 


to yaw rate. 

Range: 50 to 130. 

d. Steering Response Rate: Adjusts the rate of 

vehicle steering in order to maintain tracking 

performance. Increasing steering responsiveness 

generally results in better tracking performance. 

Higher settings: Result in better tracking 

performance but may also cause increased wheel 

motion or jittery behavior. 

Lower settings: Results in decreased wheel motion 

but may also result in worse tracking performance. 

Range: 50 to 200. 

e. Curve Sensitivity: Determines how aggressively 

AutoTrac responds to a curve in the track. This 

setting affects performance in curve track guidance 

only. 

Higher settings: Turn the vehicle in a smaller radius 

(tighter) around the curve. 

Lower settings: Turn the vehicle in a larger radius 

around the curve. 

Range: 50 to 200. 

f. Acquire Sensitivity: Determines how aggressively 

the vehicle acquires the track. This setting affects 

performance while acquiring the track only. 

High settings: Result in more aggressive line 

acquisitions. 

Lower settings: Result in smoother line acquisitions. 

Range: 50 to 200. 

5. Follow Tuning Instructions—First try to adjust the 

settings based on how it was characterized in Step 2. 

If familiar with how the settings affect performance, 

proceed to the general tuning instructions if desired. 

Although the customer’s comfort needs to be taken 

into account, try to tune the tractor based on lateral 

error on the GS3 and the tracks that tractor leaves 

behind. After finding a reasonable set of parameters, 

try running the tractor at different speeds to ensure the 

settings are still acceptable. Sometimes the settings 

that maximize AutoTrac performance are very close to 

making the operator feel uncomfortable. 

General Tuning Instructions 

Adjustment Recommendations: 


031312 

PN=33

• Steering Sensitivity—Set at 100 before making 

other adjustments – after that make adjustments in 

increments of 10. 

• Line Sensitivity Tracking—Adjust in increments of 20. 

• Line Sensitivity Heading—Adjust in increments 10. 

• Heading Lead—Adjust in increments 10. 

• Steering Response Rate—Adjust in increments 10. 

• Acquire Sensitivity—Adjust in increments 20. 

• Curve Sensitivity—Adjust in increments 20. 

One Value at a Time—Attempt to adjust the settings in 

the problem field conditions while AutoTrac is active. 

1. Start with the factory default settings. The Steering 

Sensitivity value will correlate to the value on the 

Guidance View Tap. Attempt to use a value for this 

setting that is similar to the conditions in which you are 

running (70 for concrete, 100 most conditions, 120 

for soft ground). This number may still need to be 

modified beyond the suggested settings. 

2. While AutoTrac is active in the problem conditions 

(speeds, ground, tire setup, etc), increase/reduce the 

Line Sensitivity Heading by a factor of 10. 

3. If the change in Line Sensitivity Heading is ineffective 

at addressing the issue, reset the Line Sensitivity 

Heading parameter and increase/reduce the Heading 

Lead in the same manner as the previous step. 

4. If none of the previous steps were effective reset 

the Heading Lead and increase/reduce the Steering 

Response Rate in a similar fashion to the previous 

steps. 

Combining Settings—If the above procedure does not 

give satisfactory performance and once you have become 

more comfortable with how the parameters change 

AutoTrac performance (as detailed in the previous step), 

try different combinations of parameters while AutoTrac is 

active. The following chart should be used as a reference 

and contains suggested values based on various types 

of conditions, please note that values may need to be 

adjusted beyond these recommendations to achieve 

satisfactory performance.

To return all settings to their default values, use the 

“Return To Defaults” button provided at the bottom of the 

Advanced Settings screen. 

Most Common Conditions 

1. Excessive Wheel Motion—Adjust Steering Response 

Rate first before making any other adjustments. Turn 

down this parameter until an acceptable amount of 

wheel motion exists. Although it may be possible for 

this parameter to be changed independently, you may 

need to increase Line Sensitivity Heading and/or Line 

Sensitivity Tracking (lateral) gains to compensate for 

the wheel motion decrease. Keep in mind that forcing 

this value too low may compromise AutoTrac accuracy 

because this responsiveness determines how quickly 

the system can compensate for off-track error. The 

recommended Steering Wheel Speed setting should 

be adjusted until there is slightly less wheel motion 

than what is considered excessive by the operator. 

2. Aggressive S-ing Motion—The two main 

adjustments to address aggressive s-ing motion are 

Line Sensitivity Heading and Heading Lead. Start 

by increasing Heading Lead to enable the system to 

look further ahead when making corrections. If this 

is unsuccessful, the likely cause is overaggressive 

Line Sensitivity Heading and this gain should then 

be reduced. Forcing this gain low may require an 

increase in the Line Sensitivity Tracking (Lateral) gain 

to maintain the overall system performance at an 

acceptable level. 

3. Lazy S-ing Motion—This may be the most difficult 

situation to address because the sluggish behavior 

can be caused by field conditions or machine setup. 

In some cases, tuning the gains may not achieve 

the performance desired. Start by increasing Line 

Sensitivity Tracking and check performance. If the 

system remains sluggish, increase Line Sensitivity 

Heading until the system begins to respond more 

aggressively. If fine tuning is needed, the Steering 

Response Rate can be adjusted accordingly, 

increasing this value will make the system more 

aggressive. 

Step 1: Optimize Steering Response Rate 

• Tune speed by operating parallel to and 1.2 m (4 ft) off 

of the A-B Line. 

• Activate AutoTrac Controller and observe performance. 

• While tuning, adjust in increments of 10 between the 

range of 50 to 200.

Step 2: Optimize Acquire Sensitivity 




• Tune Acquire Sensitivity until machine acquires the line 

smoothly. 

A—Desired Track—Broken 

Line 

Step 3: Optimize Line Sensitivity 

B—Actual Track—Solid Line 

A: Line Sensitivity—Tracking 

• Tune line sensitivity tracking while operating on the 

A-B line. 

• If machine wanders too far from the A-B line adjust line 

sensitivity—tracking higher. 

• If machine becomes unstable around A-B line adjust 

line sensitivity—tracking lower. 

B: Line Sensitivity—Heading 

• Tune line sensitivity heading while operating on the 

A-B line. 

• If the front of the machine wanders too far from the 

track direction adjust line sensitivity—heading higher. 

• If machine becomes unstable adjust line 

sensitivity—heading lower. 

NOTE: Line Sensitivities work together—If both are set too 

high the vehicle will become unstable. If both are set 

too low, the vehicle will wander around the A-B line.

vehicle twist. 

Steering Response Rate 

Determines the maximum speed the wheels turn to make 

corrections. Higher gains will turn the wheels faster. The 

maximum wheel speed increases with steer wheel speed 

settings from 50 to 200. From 190 to 200 the maximum 

steering wheel speed stays the same, but the rate at 

which the steering wheel accelerates increases. The 

steer wheel speed should be adjusted in increments of 

10 between 20 and 190 and in increments of 2 between 

190 and 200. Setting the steer wheel speed too high 

may cause ATU unit to deactivate. Adjust the steer 

wheel speed as high as possible without causing 

deactivations of the steering wheel. 

Higher settings: Results in better tracking performance but 

may also cause increased wheel motion or jittery behavior. 

Lower Settings: Results in decreased wheel motion but 

may also result in worse tracking performance.

Tuning Tips, Tricks, and Precautions 

• High Speed/Loose Soil Conditions 

- Tip 1: The main goal with AutoTrac is to minimize 

off-track error. In many conditions the best results are 

obtained as the production system is currently tuned 

with the default settings. 

- Tip 2: It has been demonstrated through testing that 

increased Heading Lead when operating at higher 

speeds, greater than 11 km/h (7 mph), improves 

AutoTrac stability. 

- Tip 3: Loose soil has a tendency to decrease the 

ability of the machine to steer when necessary, 

thereby decreasing performance. To counteract this 

issue increase the Line Sensitivity Heading. 

Potential tradeoffs associated with increasing Line 

Sensitivity Heading are:

Curve Sensitivity Too High 


BA31779,00003BC -19-21FEB12-12/12 

1. In some conditions the increased Heading Lead 

can lead to higher frequency instabilities. 

2. Line Sensitivity Heading is used for line acquisitions 

as well as tracking on line. Therefore, increasing Line 

Sensitivity Heading can affect line acquisitions. 

• When using AutoTrac to cross previous rows 

- Tip 1: In these circumstances it is common to 

experience excessive and repeatable side to side 

motion. Increasing Line Sensitivity Heading and 

Heading Lead can help reduce the vehicle motion. 

- Tip 2: In extreme cases, Differential Lock may be 

required in addition to the above tip to achieve 

satisfactory performance. 

NOTE: When increasing Line Sensitivity Heading and 

Heading Lead, Line Sensitivity Tracking may need 

to be reduced to prevent excessive wheel motion.

GreenStar Run Page 

Path Accuracy Indicator - Is a visual indicator of off-track 

error. The indicator consists of eight boxes on each side 

of the off-track error box. The boxes will light up indicating 

the direction the vehicle must be steered to get back on 

the AB line. Each arrow represents a distance (default is 

10 cm (4 in.)). This distance and the steering direction 

may be defined on the Lightbar Settings Page: 

GreenStar Main Page -> Settings -> Guidance Settings 

-> Lightbar Settings 

Off Track Error (A)– Off Track error is numerically displayed 

in the box. Off Track error will be displayed in cm (inches) 

up to 99 cm (35 in.). If Off Track error exceeds 99 cm (35 

in.), the distance displayed will change to meters (feet). 

Track number (B)– Represents the track number the 

vehicle is guiding on. It also shows the direction that the 

track is located from the original Track 0 for the field. 

Guidance Icon (C)– The icon represents the machine and 

implement in relative dimensions. The triangle on the 

machine represents the control point, which as used for 

guiding the machine and is defined by the machine offset 

measurements. 

GPS Indicator (D)— Indicates what level of accuracy the 

StarFire receiver is currently operating at (3D, SF2, SF1, 

RTK). If using a GPS receiver other than a StarFire, the text 

3D GPS will be displayed but the indicator bar will not fill.
