between aggressive, normal, slow, or grading blade work.
Once pressed, the machine will operate in grading mode.
Press the button again and the machine will return to the
selected blade sensitivity.
The grading icon will display on the multi-display screen.
The machine speed will decrease in the precision grading
mode. Return to normal operation by turning this function
off.
NOTE: The implement must be enabled to use this fea-
ture.

draulics screen, highlight “Lvl Inst” and press enter/con-
firm. Follow the prompts and change the “Lvl Inst” to Yes.
This will allow the leveling functions to work.
