Automatic Multiplier Shifting - Zetor FORTERRA HSX 120 Operator's Manual

AUTOMATIC MULTIPLIER SHIFTING

The system of automatic multiplier shifting is switched by multiplier pre-selection switch on the dashboard. If the multiplier pre-
selection switch is on (control on the switch is lit), the gears of multiplier are shifted automatically depending on the engine revolu-
tions according to preset values (engine revolutions).
The system of automatic multiplier shifting is not dependent on the engaged speed gear.
With engaged multiplier pre-selection switch, it is possible to turn the engine off and start and the saved values (engine revolu-
tions) do not change.
The values for automatic multiplier shifting are read always when the pre-selection switch is off, with tractor drive with engine
revolutions higher than 700 rpm, with travel speed higher than 2 km/h.
When meeting the previous conditions, the system will remember
a - Engine revolutions with last use of L button on gear shifting lever for automatic shifting of multiplier gears for lowering the
travel speed
b - Engine revolutions with last used of H button on gear shifting lever for automatic engagement of gears of multiplier for
increasing the travel speed
The difference between the engine revolutions for a and b must be greater than 250 rpm
