2.14.4 FDA drive control

The FDA drive is controlled with a switch 3 (figure 2.14.1). Indication of the FDA
drive operation is performed by an annunciator 2.
The switch 3 has three fixed positions:
- "FDA disengaged" – middle position;
- "FDA controlled automatically" – upper position;
- "FDA engaged positively" – lower position.
The mode "FDA disengaged" is used for traveling when moving on roads with hard
surface when the traveling speed is above 13 km/h in order to avoid increased wear of
front wheels.
In position "FDA automatic control" the FDA drive is automatically engaged when
the rear wheel skidding limit is exceeded and the tractor moves straightforward. The FDA
drive is disengaged automatically as the rear wheel skidding drops below the limit or the
guide wheels turn by more than 25 degrees to any side.
The annunciator 2 burns with the FDA drive engaged, and it goes out with the FDA
drive disengaged.
The mode "FDA automatic control" shall be used at various field works.
ATTENTION: IN THE MODE OF "FDA AUTOMATIC CONTROL" WITH REAR
WHEELS SKIDDING PREVENT FRONT WHEELS FROM TURNING AT ANGLES
CLOSE TO 25°, AS IN THIS CONDITION A CONSTANT ANTOMATIC ENGAGEMENT
AND DISENGAGEMENT OF FDA WILL TAKE PLACE, AND THIS CAN CREATE
ABRUPT DYNAMIC LOADS IN TRANSMISSION AND FDA DRIVE!
If there is a necessity of FDAD positive engagement, irrespective of rear wheel
skidding, front wheel turning angle, it is required to set the switch 3 into position "FDA en-
gaged positively". The FDA drive is hereby permanently engaged and the annunciator 2 is
on. To disengage the positive mode set the switch 3 into position "FDA disengaged", the
annunciator 2 will go out.
ATTENTION: OPERATING ON REVERSE USE ONLY POSITIVE ENGAGEMENT
OF FDA!
