AUTOMATIC SHIFT MODE
Mode for general dozing work When the load increases, the gear speed is shifted down automatically, and when
the load decreases, it is shifted up automatically to the maximum gear speed which has been set.
If the ripping work is performed in this mode, the setting is automatically changed to that of the manual shift
mode.
• It is suitable for the works such as digging, carrying, level-
ing, and spreading on the ground of general soil. If the op-
erating mode “P mode” is used together, the output in-
creases and a large amount of soil can be cut and carried
for a long distance.
• The power train is driven with high efficiency, so it is possi-
ble to reduce fuel consumption.
• By presetting the maximum gear speed, the gear speed is
automatically shifted to a suitable one in accordance with
the load. The work efficiency is increased and the fuel con-
sumption can be reduced.
• Available gear speed: Whole speed (F1, F2, F3L, F3, R1, R2, R3L, R3)
• Applicable operations: Dozing operation of loose soil (optimal for a long distance carrying work)
(Example)
• Slot dozing work
• Dozing work on cone-shaped ground
• General leveling work
