surface.

As Automatic Control operates, the Current position should progressively move towards the Target.

Blade Shift

The Up and Down buttons temporarily raise or lower the Target by the configured Blade Shift Increment.

Multiple adjustments can be applied as required, and the current Blade Shift value is displayed within the Blade Shift window. Selecting the displayed value allows a specific offset to be entered directly.

Because Blade Shift modifies only the Target position, the original Design remains unchanged and can be returned to at any time by removing the applied shift.

Dynamic Cut & Fill Limiting

Dynamic Cut and Fill Limiting temporarily restrict how much material Automatic Control attempts to remove or place during a single pass.

Rather than immediately targeting the finished Design, Level COMMAND calculates a temporary Target Position that respects the configured Cut or Fill Limit.

Smaller increments provide finer control, while larger increments allow quicker adjustments during grading.

Typical Blade Shift Increment values are:

These values provide a good balance between adjustment precision and operating efficiency for most grading applications.

Operator Tip: Use Blade Shift to make temporary grading adjustments as conditions change throughout the day. If large Blade Shift values become necessary to maintain the desired grade, verify the project alignment and consider performing Zero again rather than continuing to increase the applied offset.
