CAUTION For continued protection against the risk of fire, replace each of the fuses only with same type and rating of fuse.
CAUTION Always hold the steering wheel while you adjust the column tilt. Otherwise, the weight of the motor may cause the steering wheel to drop suddenly and cause damage to the steering column or dash.
CAUTION Articulated tractors pivot in the middle. Avoid putting yourself in a position where you could be injured by the pivoting rear section of the vehicle.
CAUTION Do not attach the controller to a rear window because vibration in this location can cause the controller to output false terrain compensation readings that could affect performance and cause the vehicle to swerve offline.
CAUTION Mount the controller as solidly as possible using the supplied mounting plate. If the controller is able to move, or if objects bump it, the controller may make false terrain compensation readings that could affect performance and cause the vehicle to swerve offline.
CAUTION The EZ-Steer 500 system is not designed to be mounted on machines with an open operator's station (no enclosed operator's cab). Doing so will void the warranty of the EZ-Steer 500 system components.
Open the shroud by bending the orange warning label. Remove the shroud.
CAUTION Ensure that you mount the antenna so that it is level. If the antenna is not level, GPS performance may be reduced.
CAUTION Make changes to the system settings in incremental steps. Random changes are likely to result in poor performance.
CAUTION If you increase the value in the Disengage Offline. field, the vehicle may overshoot the corners by at least a few feet.
A " screw at the center of the shaft holds the upper mount assembly to the lower mount. Loosen the screw until the screw is almost completely removed. Push the screw head until the shaft and upper mount assembly start to come away from the lower mount. (There will be some resistance due to the spring force.) Push the upper mount assembly away until the screw prevents it coming all the way out. The face of the bearing and some of the shaft will now be visible between the upper and lower mounts. Apply some molybdenum sulphide grease or black grease to the exposed shaft and bearing face. Push the two halves back together and pull them apart again. Do this several times, to spread the grease. Tighten the " screw to 5.6 Nm6.7 Nm (50 in/lb60 in/lb). Hinge the motor until it latches a few times to spread the grease around the bearing.
CAUTION Ensure that the antenna offset measurement is accurate to within 7.6 cm (3 inches). An incorrect offset can cause the vehicle to swerve offline or oscillate back and forward and may cause damage to the vehicle or other property.

Pre-Installation Vehicle Inspection
This chapter describes some examples of what to check before you install the EZ-Steer 500 system on a vehicle.
Before you install the EZ-Steer 500 assisted steering system, inspect the vehicle.
Problem Worn components Worn paint around linkage connection points The bolt has been loose in the connecting arm hole; this indicates a bad ball joint. Replace the ball joint. Cause/solution Photo

Worn ball joints

The rubber boot seal is missing. Exposure to water and dirt increases the likelihood of a worn ball joint. To check if the ball joint is loose, turn the steering wheel in short, quick motions left and right. Note If your tractor has had a front loader attached, it will almost always have worn ball joints. Replace the ball joints.
This chapter contains information on EZ-Steer 500 system disengaged warning messages, T2 technology system warnings, and EZ-Steer 500 system fault codes.
EZ-Steer 500 system disengaged warning messages
Messages appear at the top of the screen when the system disengages.
Torn rubber boot seal around ball joint from poor lubrication
To check if the ball joint is loose, turn the steering wheel in short, quick motions left and right. Check the inner and outer tie rod ball joints for problems. If the ball joint moves a small distance before the connecting arm turns, replace the ball joint.

Troubleshooting

Problem Worn splines Cause/solution In some 2WD tractors, the connecting arm is bolted onto a splined wheel hub shaft. Turn the steering wheel with short, quick motions left and right. The connecting arm should move immediately with the wheel. If you notice a small amount of connecting arm movement before the wheel turns, it is likely that the splines are worn. Replace the front wheel hub shaft. On MFWD tractors with a rigid front axle, turn the steering wheel and watch the front wheels turn. If the axle moves forward or backward as you turn the steering wheel (see the white arrows), replace the axle pivot pin bushing. Photo
Possible cause The controller orientation is incorrect. Solution Check that the controller is correctly installed and configured. See page 27.
Problem The vehicle steers offline immediately after engaging. The controller LED is flashing on and off evenly. The controller LED is flashing with the LED off longer than it is on. The controller LED is flashing very fast.
This is normal operation.

Do nothing.

The CAN communication has been lost.

1. Check that the cable connection is secure. 2. Check that the cable is not damaged. Check all equipment and cables for damage. If there is no damage: 1. Download the error log to a USB Flash Drive 2. Send the error log to your local reseller.
Worn front axle pivot pin bushing
There is a controller fault.
Worn steering cylinder pins and bushings
On articulated 4WD tractors, turn the steering wheel and check for play in the steering cylinder pins. If you can see either of the cylinder rods move slightly before the tractor starts to hinge left or right, you must replace the pins and bushings.
Problem Worn steering shaft causes loose steering wheel Cause/solution A steering column with play in all directions (see white arrows) can cause the steering shaft to bind against its housing when the pressure of the EZ-Steer motor is applied, making it difficult for the EZ-Steer motor to turn the wheel. Repair or replace the steering shaft. Photo Problem The vehicle runs parallel to the line Possible cause The Aggressiveness setting is too low. The vehicle has greater Freeplay in one direction than the other. Solution
Increase the Aggressiveness in increments of 10% up to a limit of 130%. Configure the Freeplay offset setting: 1. Select Configuration / Auto Steer / EZ-Steer Setup / Vehicle Setup. 2. When the vehicle is offline: to the right, increase the Freeplay Left field by 0.30 cm (0.1") and decrease the Freeplay Right field by 0.30 cm (0.1"). to the left, increase the Freeplay Right field by 0.30 cm (0.1") and decrease the Freeplay Left field by 0.30 cm (0.1"). 3. Test the new setting. Adjust the Freeplay Left and Freeplay Right values by a further 0.30 cm (0.1") if necessary. Repeat the process until the vehicle makes only small deviations (5.1 cm15.2 cm (2" 6")) either side of the line.
Wheel problems Uneven tire pressure Tires mounted on the same axle must be inflated to the same pressure. This improves machine stability by preventing cab roll, and reduces the effort required to turn the front wheels. If the tractor front tires are filled with a fluid such as calcium chloride, slightly increase the Aggressiveness setting in the EZ-Steer 500 system. For some tractors, you may need to clamp a bracket directly onto a telescoping steering column. Ensure the steering column telescope lock/unlock knob is working correctly. If the steering column cannot be set in a fixed position, the column could telescope freely inward, causing the bracket to strike the instrument panel.

Telescope lock does not hold column in place
Problem Cause/solution A steering wheel with vertical play (see white arrow) does not provide good contact with the EZ-Steer 500 system drive wheel. The drive wheel could slip on the steering wheel outer ring, causing a loss in steering accuracy. Tighten the steering wheel. Photo

Offline

Possible cause GPS error. T2 terrain compensation is not calibrated correctly. Solution Refer to General GPS, page 57. Repeat the EZ-Steer Calibration wizard.
Problem The lightbar shows online but when I look at the marks from my last pass, I see gaps. The vehicle is slow to get online
Steering wheel is loose on steering shaft
The Angle per Turn value is too high. The Aggressiveness setting is too low. (4WD vehicles) The Motor Speed is too low. The T2 terrain compensation is not calibrated correctly.
Repeat the EZ-Steer Calibration wizard. Repeat the EZ-Steer Calibration wizard. Set the Motor Speed. Repeat the EZ-Steer Calibration wizard. Move the vehicle closer to the line with a shallower angle before engaging. Increase the Maximum Angle and Disengage Offline settings from Configuration / Auto Steer / EZ-Steer Setup / Engage Options. Steering wheel is dirty Front steering is out of alignment
The EZ-Steer 500 system overshoots the line and disengages.
The vehicle is approaching the line at too steep an angle. The engage limits are too narrow to allow the vehicle to maneuver onto the line.
If one or both of the front wheels are out of alignment, the steering will pull to one side and the machine will constantly steer to the left or right and will have problems following a straight or curved line. Fix the machine's front wheel alignment before installing and calibrating the EZ-Steer system. Grease, oil, or protectants such as Armor All may cause the foam drive wheel to slip on the steering wheel. Use denatured alcohol to clean the steering wheel.
Problem No power from accessory socket Cause/solution Plug in the EZ-Steer power cable and flip the switch on the male power adaptor. If the accessory socket has power, the green light on the switch is lit. Photo

Headlands

It is possible to engage the EZ-Steer 500 system on headlands which have sharp corners at the edge of the field. However, the EZ-Steer 500 system may be unable to drive around these sharp bends. Use one of the following methods to compensate:

Sprayer

Manually steer the vehicle around the corner. Once you have rounded the corner, re-engage the EZ-Steer 500 system. Select Configuration / Auto Steer / EZ-Steer Setup / Engage Options and increase the Disengage Offline distance.
STEP 4: Connecting optional switches
You can connect one of the following switches to the EZ-Steer 500 system:

Engaging

Before you can engage the EZ-Steer 500 system, you must define an AB Line, and drive the vehicle close to the guidance swath. Before engaging, point the nose of the vehicle towards the guidance line and drive at operational speed. When the system indicates it is ready to engage, do one of the following:

Calibrating Online Aggressiveness
The Online Aggressiveness setting controls how aggressively the EZ-Steer 500 system holds the guidance line once it is online.
STEP 4: Calibrating EZ-Steer 500 system settings
Minimizing offline distances
The calibration of all parameters involve engaging the EZ-Steer 500 system on a guidance line, then changing the parameter until you have minimized the offline distances.
STEP 1: Starting the EZ-Steer Calibration wizard

Press o to take the second calibration reading. This takes approximately 20 seconds. Do not move the vehicle while the offset is being read. Review the roll calibration settings.
Measure the distance from the ground to the top of the GPS antenna. 4. Enter the antenna to axle offset.

Note The Roll offset should have a value between 0 and 4, and a left or right offset indicated by a L or R symbol.
Measure the distance from the reference point to where the antenna is mounted. The reference point for each vehicle is:
Vehicle type 2WD tractor 4WD tractor Sprayer Reference point Rear axle Nose of the vehicle Rear axle
The following table shows the measurement of antenna offset for each vehicle type and antenna mounting location.
STEP 3: Completing T2 roll calibration
Roll compensation uses the T2 terrain compensation technology in the EZ-Steer controller. Follow the on-screen instructions to complete the T2 roll calibration. 1. Select the direction that the controller connectors point.
4WD (articulated tractor) Sprayer
Note Take particular care to ensure that the correct direction of offset from the antenna mount reference mount is selected.
Park the vehicle and mark the inside position of both sets of wheels.
Press o to take the first calibration reading. This takes approximately 20 seconds. Do not move the vehicle while the offset is being read.

Prevent Seed Overlap with Field-IQ Section Control and Tru Count Clutches
Automatically control up to 48 rows individually for maximum control Eliminate seed overlap in your headlands and point rows with Tru Count Meter Mount air clutches Field-IQ system is compatible with the FmX integrated display, EZ-Guide 500 system and all Tru Count clutches
Vary Rate of Fertilizer or Lime Using a Prescription Map, Field-IQ Variable Rate Control and Rawson Drives
Load a Variable Rate Application prescription map using EZ-Office Pro software or your agronomist into your FmX integrated display or EZ-Guide 500 system Deliver the precise rate of seed with your Rawson PAR 40 variable rate drive No more over application of fertilizer to areas that cant hold or use the nutrients Apply the correct amount of lime to manage your soil's PH in every location
Get Your Soil in Shape While Spreading or Strip Tilling with the Field-IQ Section and Variable Rate Control
Utilize the built-in GPS Receiver and digital camera on the rugged Trimble Nomad or compact Juno SB handheld computers and EZ-Office Mobile software to capture geo-referenced pictures of problems such as weeds and insects Vary the rate of your liquid fertilizer application using your FmX integrated display or EZ-Guide 500 system and a Rawson drive Easily shut off liquid fertilizer for individual rows with new Tru Count LiquiBlock valves. The valves easily connect to Tru Count air clutches, sharing the same air source, allowing growers to simultaneously shut off seed and liquid
Vary Seed Population in Your Field with Field-IQ Variable Rate Control and Rawson Drives
Change the seed population rate to match soil potential throughout the field Manually adjust your seed population rate or use a prescription map from EZ-Office software and an FmX integrated display or EZ-Guide 500 system to automatically set the rate of seed Apply a high population to fertile soils to maximize yield potential while reducing the rate on less fertile soil

FIELD-IQ CROP INPUT CONTROL SYSTEM: A MODULAR, SECTION CONTROL AND VARIABLE RATE APPLICATION CONTROL SYSTEM. EXPAND AS YOU GROW
WHAT CAN THE FIELD-IQ SYSTEM DO FOR YOU?
New! Control up to 48 rows
Reduce overlap with automated individual row control. Use less seed and reduce seed costs. The FmX integrated display or EZ-Guide 500 system automatically controls up to 48 rows.
New! Tru Count Meter Mount air clutches
New! Tru Count Meter Mount clutches fit most styles of John Deere, Case IH and Kinze planters.
New! Tru Count LiquiBlock valves

New! Also shut off liquid fertilizer with LiquiBlock valves.

Rawson rate control

Instantaneous rate response with Rawson PAR 2 or PAR 40 variable rate drives. No lag at beginning of pass so seed and liquid is applied at a steady rate. Control the Rawson drive directly with the FmX display or EZ-Guide 500 system; no ACCU-RATE controller needed.
Automatic overlap detection
Your FmX integrated display or EZ-Guide 500 system automatically tracks where youve been and what youve done. No need to manually start and stop application.

New! Master switch box

Small, mountable, master switch box for a quick access to common functions such as rate change and manual / automatic section control. Includes a new "jump start" function which allows a standard application speed to be preset, so the correct flow can be achieved before the start of a row or continue if GPS signal is lost.
New! GreenSeeker system compatibility with FmX integrated display
FmX display now functions as the cab interface for GreenSeeker optical sensing system, controlling job setup, monitoring and storage. Easier installation and operation, more reliable performance and less cab clutter. Priced below the non-integrated GreenSeeker system.
