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 design, the system is not cutting and filling as per map on screen.
Causes:
Base is being used as a Quick Survey base.
Base power is low.
iGrade and/or application controller need to be updated.
Solutions:
Use an Absolute Base.
Charge base to fullest amount.
Mount GPS receiver so that it moves with the blade.
Contact your John Deere dealer and ask if updates are available for iGrade and/or application controller.
