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 Plane Control, or Grade Control

Drain design bottom width is narrow and the implement is traveling outside the design width. The user is working outside of the drain bottom width design so the blade is not going to the design height.

Solutions:

Place iGrade in “Remote Control” mode and cycle power on the tractor. Consult your iGrade manual for instructions.

Increase the width of the drain bottom in Drain Design to accommodate the desired drain path.
