“-1”: Approximately 20 % slower than forward travel speed.
“0”: Same as forward travel speed.
“+1”: Approximately 20 % faster than forward travel speed.
“+2”: Approximately 40 % faster than forward travel speed.
“+3”: Approximately 60 % faster than forward travel speed.
By setting the travel speed according to the operation in advance, gear shifting is not necessary when operating
the joystick (steering, directional and gear shift lever).
T
o improve efficiency in dozing operation, increase the reverse travel speed.
When traveling in reverse on the rough ground or dozing uphill, decrease the reverse travel speed.
