WORK EQUIPMENT AUTOMATION SWITCH
The work equipment automation switch is used for turning
ON/OFF the functions of auto-pitch and ripper auto-return.
When this switch is turned ON, the auto-pitch and ripper auto-
return functions can be used in the mode set on the Mode Se-
lect screen.
If the auto-pitch and ripper auto-return functions are turned
OFF on the Mode Select screen, the auto-pitch and ripper au-
to-return functions cannot be used even if the work equipment
automatic setting is pressed.
When the starting switch is turned ON, the auto-pitch and rip-
per auto-return functions are turned OFF as the default.
The states of the auto-pitch and ripper auto-return functions are
indicated on the machine monitor screen (A).
AUTO-PITCH
(Only machines equipped with dual tilt function)
Auto-pitch is a function to automatically control the blade pitch angle properly for digging and dozing.
• Since the pitch angle does not need manual control, the operator's fatigue is reduced.
• The operator can enable/disable this function by using the work equipment automation switch on the moni-
tor switch section.
• The auto-pitch function has 2 modes; auto-pitch mode and digging position set mode. The operator can set
either of them on the customize mode selection screen.
Also, the operator can add the auto-pitch reverse interlock function by turning ON the Auto-pitch reverse
interlock on the customize mode selection screen.
• The operator can check setting of the auto-pitch function
by display of auto-pitch pilot lamp (M) displayed on the
machine monitor.

terlock are OFF (blue).
