SYSTEM / Control System

Purpose: When the ECO mode of the ECO mode switch is selected, engine speed can be limited. Therefore, the fuel consumption is less than the normal mode

Operation:

When ECO mode is selected:

• When the ECO mode of the ECO mode switch is selected, the ON signal is sent to the HST control unit.

• According to the input signal the HST control unit controls the displacement angle in order to limit the HST motor maximum displacement angle.

When normal mode is selected:

• When the normal mode of the ECO mode switch is selected, no signal is sent to the HST control unit.

• Therefore, the HST motor maximum displacement angle is not limited.
