Paddle pots are backwards for manual control of cross slope.
Symptoms: The operator is accustomed to moving the controls in one direction to achieve left tilt and in the other for right tilt. iGrade v1 wants the cross slope ram hoses in a certain way and this forces manual control to be backwards from how the operator...
Scraper cross slope appears to be the opposite of what it should be.
Symptoms: When T3RRA is commanding a cross slope tilt to one side the scraper blade is doing the opposite. iGrade is showing a current cross slope % as positive when the implement is rolled to the left, and negative when tolled to the right. Reversing hydraul...
Troubleshooting performance.
Symptoms:Implement responds too slowly to changes in gradeBlade fails to hold gradeUnexpected shifts in blade elevation occurImplement appears not to respond to commandsCross slope not workingCross slope behaving unexpectedlyCause:“Performance” is a subjective...
Implementing issues with iGrade (will occur without T3RRA connected)
NOTE: There will be situations where your dealer may ask you to capture a StarFire message log for further diagnosis. This can be done on the Deere display using the SF6000 VT as follows:
Bi-Directional error in iGrade.
Symptoms:The implement consistently cuts when heading in one direction and fills in the other direction. Final grade is never achieved. If T3RRA software is halted and iGrade is run in ‘Plane Control’ only the problem is still present. Changing height control ...
Blade continuously loads on one side.
Symptoms:System is grading low on one side.Cause:There are multiple possible causes for this.iGrade has not been set correctly.SCV’s have been put accidently in float instead of detent.Manual nudge controls have been turned on by accident.Solutions:Ensure this...
Poor “on grade” performance.
Symptoms:Blade Struggling to hold grade.Cause:There are multiple possible causes for this issue.Interruptions to GPS.Incorrect surface offset.Incorrect settings in iGrade.Solutions:Disconnect T3RRA software. Perform performance tests using iGrade alone to simp...
Engaging auto causes the scraper to raise into the air.
Symptoms:Operator engages scraper into detent (auto mode) and the scraper extends to full stroke on the lift cylinders.Cause:iGrade has Load Limiting and/or Max Cut enabled in Application controller settings.The engine speed (RPM) threshold is set lower than t...
Scraper is “washboarding”.
Symptoms: Scraper causes a washboard effect. A-If washboarding is close together, flow rate is too high. B- If washboarding is far apart, flow rate is too low. Cause: SCV flow rate is set too high or too low. Washboarding can occur when the blade is ...
Implement blade moves to an extreme position when placed in Auto.
Symptoms: When placing the machine in Auto, the implement’s blade dives deep, climbs to full height, or tips fully to one side. Cause: SCV hoses are incorrectly configured (reversed). UCC2 with JD proprietary mode configured for SCV control but JD Lega...
Blade not staying on grade & acting inconsistently.
Symptoms:Blade is acting erratically.Blade height is on grade for a while but then moves down a few inches and then back up.Blade is reacting inconsistently while implementing. The blade wants to cut over ground that is already on grade.When implementing desig...
The implement blade does not seem to follow the design surface.
Symptoms:The blade is moving up and down in ways that indicate that it is being successfully controlled. However the blade positions do not seem to be what is expected based on the design in T3RRA. Cause: iGrade is not in “Remote Control” mode. It may be in Pl...
Implement blade is intermittently jumping up or attempting to deep dive.
Symptoms: Work is progressing normally but occasionally the blade will suddenly rise up, or attempt to aggressively dig. Possible Cause: A bad USB-to-Serial conversion dongle/adapter is causing corrupted height commands to be sent to iGrade. This can b...
Erratic performance during drain implementation.
Symptoms:Implement moving erratically while implementing drains.Implement moving erratically while implementing drains with Cross Slope enabled.Cause:T3RRA creates a surface using a raster which is a grid of elevation heights. These gridded cells are referred ...
iGrade is indicating that Remote Commands are not being received from T3RRA software or indicating ‘No Surface Defined’.
Symptoms: The iGrade display is showing a “No Remote Commands” error message, and iGrade is not controlling your implement. iGrade v2 displays “No Surface Defined” when moving. Causes: Your T3RRA software may not actually be sending control messages. ...
Error from grade values do not match on iGrade and T3RRA software.
Symptoms:When stationary, or at very low speeds, the value for error from grade reads 0 on the iGrade display. The error from grade value in the T3RRA software is non-zero and at the expected error value. As soon as you start moving the error value on iGrade r...
User cannot turn “Grade On” with iGrade 2.
Symptoms: You have iGrade setup for remote Control. You have a field design in T3RRA Cutta with your zero set and you are on the design surface in the field. You select the “Grade Off” button to turn “Grade On” with no luck. You have checked T3RRA Cutta to ...
Poor as-applied coverage.
Symptoms:The as-applied map looks blotchy, streaky, incomplete, or otherwise incorrect.Cause:The as-applied map will only be correct for a single machine working in a field. If part of the field is done by another machine this information will not be relayed t...
