While tractor movement, there is a possibility of automatic switching of reduction unit
passes on range “B” (without tractor stop).
To speed up the tractor, it is required to depress the clutch pedal on the fourth gear of
pass “L” and hold it in this position, press the joystick handle forward against the stop. In this
case, automatic switching to the second gear and changing of the pass from “L” to “H” take
place. After switching is carried out, CECS switches on the built-in buzzer for a short time, af-
ter which it is required to release the clutch pedal smoothly.
To slow down the tractor, it is required to depress the clutch pedal on the first gear of
pass “H” and hold it in this position, press the joystick handle backwards against the stop. In
this case, automatic switching to the fourth gear and changing of the pass from “H” to “L” takes
place. After switching is carried out, CECS switches on the built-in buzzer for a short time, af-
ter which it is required to release the clutch pedal smoothly.
2.14.4 Switching of GB reduction unit passes
When turning the starter and instruments switch to the position “I” – instruments on” an
annunciator of GB reduction unit 17 (figure 2.15.1) engaged state on CECS switches on. The
pass, which was switched on before engine stop, is in the engaged state – consequently, the
switching on annunciator for the corresponding pass of GB reduction unit 15 or 26 lights up.
Switching of GB reduction unit passes “L” (lower) and “H” (higher) is possible only after en-
gine start, when the transmission hydraulic system pump starts to operate.
ATTENTION: SWITCHING OF GB REDUCTION UNIT PASSES SHALL BE CARRIED
OUT ONLY WITH THE TRACTOR STOPPED AND THE LEVER FOR SWITCHING GB
RANGES SHALL BE SET IN THE NEUTRAL POSITION!
Switching on of GB reduction unit lowest pass “L” shall be carried out with button 25
(figure 2.15.1) located on CECS. By doing so, annunciator 17 burns on CECS and annunciator
for switching on GB reduction unit 26 lowest pass lights up. Annunciator 15 goes out.
Switching on of GB reduction unit highest pass “H” shall be carried out with button 16
(figure 2.15.1) located on CECS. By doing so, annunciator 17 burns on CECS and annunciator
for switching on GB reduction unit 15 highest pass lights up. Annunciator 26 goes out.
Switching of GB reduction unit passes (“L”/”H”) is also possible by pressing button 5 (fig-
ure 2.14.1) located on the lever for switching ranges 3.
