This mode is recommended for normal soil quality and operations, such as digging,
hauling, grading, and leveling.
The power train is driven with high efficiency, so it is possible to reduce fuel consump-
tion.
The optimum travel speed is automatically selected and gear shifting is performed
with no shock, so there are no troublesome gear shifting operations.
Use this mode for digging and ripping operations on rough ground or where the load
changes easily.
Use this mode for operations and removing stumps or for side cutting, where deceler-
ation operations are needed.
Full power is generated, so use this mode for operations on uphill slopes or when
handling large volumes of soil.
Use this mode when it is desired to reduce fuel consumption.
Use this mode for soil or operations where the shoes tend to slip and where decelera-
tion operations are needed.
Use this mode for pushing-down operations and grading operations where power is
not needed.
