3.3 Operating the engine to regenerate the
DPF for parked regeneration
(1) Parked regeneration switch
(2) DPF INHIBIT switch
(3) Regeneration indicator
(4) Parked regeneration indica-
tor
(5) Engine rpm increase indica-
tor
(6) Engine warning indicator
1. Park the tractor in a safe area away from buildings,
people, and animals.
2. Apply the parking brake.
3. Set the following pedal or lever to the “NEUTRAL”
position.
• [Manual transmission type]
Set the synchro-shuttle shift lever to the
“NEUTRAL” position.
• [HST type]
Set the speed-control pedal to the “NEUTRAL”
position.
4. Set the following lever or switch to the “NEUTRAL”
position.
• [Manual transmission type]
Set the PTO gear-shift lever to the “OFF”
position.
• [HST type]
Set the PTO clutch-control switch to the “OFF”
position.
5. Return the engine rpm to the idle speed.
6. Lower the implement to the ground.
7. Turn the steering wheel to become the front wheels
in the straight ahead position.
8. Press the DPF-INHIBIT switch .
The DPF INHIBIT-switch lamp turns “OFF.”
When the regeneration conditions are satisfied
(step 2. to step 5. and step 7. mentioned
previously), the parked regeneration-switch lamp
starts flashing.
9. Press the parked-regeneration switch to start
the regeneration cycle.
The parked regeneration-switch lamp will stop
flashing and remain “ON” constantly during the
regeneration cycle.
The engine rpm will automatically rise, and the
regeneration process will begin.
Regeneration process
a. Both indicators and stay “ON”
while regenerating the DPF.
b. Indicators
and turn “OFF” when
the regeneration cycle is complete.
c. After the lamps
and turn “OFF,”
normal tractor work may resume.
10. When driving in regeneration-inhibit mode, press
the DPF-INHIBIT switch to turn on the DPF
INHIBIT-switch lamp.
NOTE :
• During the regeneration cycle, do not touch
the levers and switches (mentioned
previously in step 2., step 3., and step 4.),
nor change the engine rpm other than for an
emergency stop. Otherwise, the
regeneration will be interrupted.
• Never leave the tractor when the parked
regeneration process is activated.
• If the parked regeneration cycle is
interrupted, the engine rpm is fixed at the
idling level for about 30 seconds. For 30
seconds when the engine rpm is fixed, keep
the hand-throttle lever and foot-throttle
pedal at the idle position. Do not move the
hand-throttle lever and foot-throttle pedal.
The hand-throttle lever and foot-throttle
pedal will function again in 30 seconds.
4. Tips on diesel particulate filter
(DPF) regeneration
• Operation
The higher in speed or load the engine operates,
the higher the exhaust temperature rises. As a
result, particulate matter (PM) inside the DPF is
consumed, therefore the regeneration process is
required less frequently over time.
The lower in speed or load the engine operates, the
lower the exhaust temperature. Accordingly, less
particulate matter (PM) inside the DPF is consumed
and more accumulation of PM will occur, which
requires frequent regeneration. Therefore, avoid
prolonged idling if possible.
