2.16 FDA drive control
The control switch of the FDA 1 has 3 fixed positions:
- “FDA disengaged” – extreme lower (front) position. This mode is used for transport opera-
tions when moving on roads with hard surface;
- «FDA controlled automatically» – middle position. In this mode the FDA is engaged and dis-
engaged with a help of overrunning clutch, depending on the rear wheel skidding. This mode
shall be used at various field works.
- «FDA engaged positively» –extreme upper (rear) position. This mode shall be used only
when the rear wheel skidding is constant or by the reverse movement, when the engagement
of the FDA is necessary.
The modes «FDA controlled automatically» and «FDA engaged positively» shall be used when
the tractor starts the movement.
When the tractor starts the movement, you should switch the FDA drive from the position
«FDA controlled automatically» and «FDA engaged positively» to the position «FDA disen-
gaged» with the clutch pedal fully depressed. If the disengagement of the FDA drive is compli-
cate, don’t switch it by force and do following:
- depress the clutch pedal;
- shift the gear to change the direction of movement to opposite (if the forward gear was
on, you should put the reverse gear and vice versa);
- release slowly the clutch pedal and starting the movement switch the control lever to
the position «FDA disengaged».
