2.15.4 Front power take-off shaft control
Front power take-off shaft control is similar to RPTO control.
Front power take-off shaft control is carried out by means of buttons 3 and 37 (figure
2.15.1). Indication of FPTO operation is carried out with annunciators 2, 38, 39.
In the initial state, when operator shifts the starter and instruments switch to the position
“I” – instruments on”, FPTO disengaged state is set by default – indicator 38 burns which con-
firms FPTO disengaged state.
To engage FPTO, it is required to press button 3. Immediately after pressing button 3,
annunciator 2 gets actuated which informs
the start of FPTO spinning up. Then, after some
time when FPTO gets to the normal operation mode, annunciator for FPTO 39 engaged
state lights up additionally.
To disengage FPTO, it is required to press button 37. By doing so, annunciators 2
and 39 go out and annunciator for FPTO switching off 36 lights up which confirms that
FPTO is in the disengaged state.
ATTENTION: FOR FRONT POWER TAKE-OFF EMERGENCY SWITCHING OFF, IT
IS REQUIRED TO PRESS BUTTON 1 (FIGURE 2.15.1)!
Note – Additional information on operating rules with FPTO are specified in subsection
3.2.7 “PTO use”.
2.15.5 Front driving axle drive control
Front driving axle drive (FDAD) control is carried out by means of buttons 12 and 30
(figure 2.15.1). Indication of FDAD control is carried out with annunciators 10, 11, 31.
In the initial state, when operator shifts the starter and instruments switch to the position
“I” – instruments on”, FDAD disengaged state is set by default.
Mode “FDAD off” shall be used on the transport when moving on roads with hard sur-
face at a speed of over 13 km/h to avoid increased wear of front wheels tires.
When pressing button 12 “AUTO” with the position of guide wheels corresponding to
straight-forward movement and with excess of skidding limit for rear wheels, FDA drive gets
actuated in an automatic mode. Simultaneously, annunciators 11 and 10 light up.
FDAD disengagement is carried out automatically when guide wheels turn for the angle
over 25° or at a speed of over 16 km/h, or at reduction of rear wheels skidding below the per-
missible limit. At speed reduction less than 13 km/h or excess of rear wheels skidding limit dur-
ing straight-forward tractor movement, FDA drive shall switch on automatically. Annunciator for
switching on FDAD automatic mode 11 shall constantly burn up to the moment of switching off
this mode, and annunciator for FDAD engaged state 10 shall burn only during FDAD opera-
tion.
Mode “FDAD automatic control” shall be used at different types of field work, including
reverse movement.
ATTENTION: AVOID FRONT WHEELS TURNING AT ANGLES CLOSE TO 25° IN
THE MODE “FDAD AUTOMATIC CONTROL” WITH REAR WHEELS SKIDDING, AS BY DO-
ING SO CONSTANT AUTOMATIC FDAD SWITCHING ON AND OFF TAKES PLACE,
WHICH CAN CREATE ABRUPT DYNAMIC LOADS IN TRANSMISSION AND FDA DRIVE!
Disengagement of mode “FDAD automatic control” is carried out by repeated pressing
button 12 “AUTO” or by pressing and releasing button for switching on FDAD forced mode 30.
By doing so, annunciators 10 and 11 go out.
In case FDAD forced switching on is required, regardless of tractor speed and front
wheels turning angle, press button 30. Simultaneously, annunciators 10 and 31 light up. At re-
peated pressing button 30, FDAD forced switching off takes place and annunciators 10, 31 go
out.
To pass from the automatic mode of FDAD switching on to the forced mode, it is
enough just to press button 30 and hold it in this position.
