Look ahead delay time
To control blade height, the software receives an elevation from iGrade™, processes it, then returns a control signal to iGrade™. Although this control loop is quick, its delay can cause inaccurate implementation in some situations.
A normal “Look ahead” time is 0.3 to 0.5 seconds. The exact time is machine specific and can be determined by experimentation; see Bi-Directional error in T3RRA in the troubleshooting section. Look ahead time helps account for the control-loop delay.
If look ahead time is not set, the delay can cause a consistent “bi-directional error”: the blade offsets incorrectly, moving up when travelling down a slope and down when travelling up a slope. If the time is too LOW, the implement always grades high down-slope and low up-slope; if it is too HIGH, the opposite occurs. Bi-directional error is most noticeable on steep slopes at higher speeds.
Blade positioning
Blade positioning specifies which part of the soil profile under the blade has priority in determining blade position. This option is available only after you enter ‘Implement width’ and enable ‘Output cross slope commands’.
Blade positioning options
Classic uses the design elevation as the target under the blade centre. Cross-slope is determined by design elevations under the left and right blade points. This makes it easy to over-dig down the midline of ditches or clip the top off a bank when straddling its ridge.
Average follows the overall trend of the design surface under the blade. It works well for reproducing a full-field design, but is less suited to abruptly changing slopes.
Average, on top determines slope in the same way as Average, but positions the blade above that trend to always avoid overcutting.
Snap fit attempts to find the best blade position without overcutting. As you traverse a break line, the blade snaps from one position to another. This is intended to cut and fill most efficiently, minimising passes and rework risk, and is tailored for abruptly changing slopes.
Single point provides Control-by-point: choose a blade position represented by the red arrow. That point follows the design elevation and cross slope even if the blade cuts below the design elsewhere. This is envisioned to work well for features such as V-ditches.
As-applied tracking
Enable As-applied calculations shows a graphic representation of the surface’s current state as work progresses. See Understanding how “As-applied” works.
NOTE: ‘Implement width’ is required to enable the As-applied feature.

Blade shift increment
Blade Shift Increment sets the height adjustment applied by the up/down elevation adjustment buttons in the implementation wizard step.
Limits tab with Blade Shift Increment, Static Blade Limit and Dynamic Blade Limit controls; As Applied is required
NOTE — The recommended blade shift increment is 0.03 - 0.06 feet (0.4 - 0.8 inches, or 0.01m - 0.02m).
Static blade limit
Static Blade Limit temporarily changes target design heights by a specified amount. At 50%, target cut and fill heights become 50% of the design values. It can also overfill a design by a percentage to allow for soil to sink over time: at 110%, a 100mm fill becomes 110mm to allow for future compaction.
Build banks, roads or mounds in gradual steps to allow even compaction of dirt.
Ignore cuts is useful when gradually building a mound. Use the vertical nudge to lower the design surface below the current surface, then slowly nudge it upwards so filling begins at the apex and proceeds outwards. In this case, avoid cutting where the nudged mound design is below the original surface. NOTE: Ignore cuts can be activated even when Static Blade Limit is set to “None”.
Set the static blade limit amount on the implementation screen.
Methods for progressively adding layers of dirt to a fill area
Static Blade Limit by Percent — Static Blade Limit by Percent: dashed curved layers progressing from the original surface towards the mound design
Static Blade Limit By Absolute Value — Static Blade Limit by Absolute Value: horizontal dashed fill layers beneath a curved mound design
Combination of vertical blade offset + Ignore cuts — Vertical blade offset with Ignore cuts: dashed mound profiles rising from below the original surface

5.5 | GPS Port Settings Tab
GPS connection settings
GPS settings with Raw GPS Data displayed
GPS displays the COM port used to communicate with the GPS. Select the correct port from the drop down menu.
Baud (Rate) sets the communication speed between the software and GPS. It should match the GPS baud rate.
Scan for GPS checks available COM ports and usual baud rates for valid GPS data.
NOTE: T3RRA software and iGrade™ must have identical Com port and Baud Rate settings in order to communicate.
Configuration and diagnostics
Warning/Error Configuration settings changed on this page remain in effect after the system is turned off.
Current displays the most recent GPS information received in a table.
Raw GPS data displays the most recent GPS data received. It is primarily used for diagnostics when support is required.
Output Data displays the most recent outgoing communications. It is primarily used for diagnostics when support is required.
Recent GPS errors lists the most recent GPS errors so that intermittent errors can be reviewed.
Open Device Manager is used to investigate COM port issues when required.
Connect and Disconnect manually start or stop communication with the app controller.
Serial port parameters
Com port: The adapter assigns the Com port #. The drop-down box lists all available com ports. Select the serial port physically connected by cable to the iGrade™ Application Controller. Windows Device Manager provides diagnostics for the current serial ports; you can open it using the button at the bottom left of Settings > GPS.
Baud rate: This is the speed of communication with iGrade™. It must match the iGrade™ settings, or T3RRA software cannot communicate with iGrade™. For iGrade v1, the recommended baud rate is 38400. For iGrade™ v2, the recommended baud rate is 115200, with NMEA Message Type set to “All”.
Warning Thresholds
Idle timeout: An error warning appears if no GPS messages are received within this time period.
RTK Timeout: This monitors the time since the last good RTK correction packet. It should not normally be set above 10-20sec.
Max VDOP: Vertical Dilution of Precision measures altitude accuracy. Keep this value as low as possible for the most accurate implementation, but setting it lower than 2 may interrupt use of T3RRA software.
Min Satellite Count: Sets how few satellites the GPS needs to see before a warning appears.
