Travel speed is set to suit the general work load and gear shifting is easy. This is ef-
fective for the operator who is accustomed to 3 speeds gear shifting pattern or for the
work which requires frequent gear shifting.
Travel speed can be set in 20 levels between 0.8 and 9.0 km/h {0.5 and 5.6 MPH} .
In particular, minimum travel speed is set low and it ensures the safe work for loading
to the trailer or riding over unevenness of the road.
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.
Engine high idle speed is set higher compared with P mode, and it is easy to control
the load.
Fuel consumption becomes larger than P mode.
Depress the decelerator/brake pedal, and travel speed and engine speed lowers.
Use this mode for general operations.
Depress the decelerator/brake pedal, and the travel speed lowers, but the engine
speed does not lower.
Use this mode when you want to lower the travel speed but keep the work equipment
speed.
Starting of operation for blade RAISE and LOWER becomes quick, and movement of
the work equipment corresponding to the lever stroke also becomes quick.
Blade response of RAISE and LOWER is optimized for general operations.
Starting of operation for RAISE and LOWER becomes smooth, and the operating
range on the lever stroke corresponding to the movement of the work equipment be-
comes wider.
