Type Conditions Description
Parked
Manually initiate a parked regeneration as
soon as possible. A parked regeneration
will take approximately 30 to 60 minutes
and should not be started with less than
1/4 tank of fuel. The machine must remain
stationary (cannot be operated) during
the entire parked regeneration process.
The engine ECU adjusts the exhaust
intake throttle to raise the exhaust
temperature.
For all software revisions: the InfoCenter
displays advisory #188 and/or the stationary
regeneration icon.
Recovery Occurs when exhaust back pressure in
the DPF increases due to soot buildup
reaching a critical level.
Can only be initiated when prompted by
the engine ECU.
For software 122-0251E and up: the
machine mow function (PTO) will be
disabled at first notification.
Manually initiate a recovery regeneration as
soon as possible. A recovery regeneration
will take approximately 3 hours and
should not be started with less than 1/2 tank
of fuel. The machine must remain stationary
(cannot be operated) during the entire
recovery regeneration process.
Use the InfoCenter About screen to verify
the software installed on the machine.
Occurs when exhaust back pressure in
the DPF increases due to continued soot
buildup. May be caused by prolonged
operation at low engine speed, low engine
load, or the use of incorrect fuel or engine
oil.
May occur if the InfoCenter is set to inhibit
regen (preventing a Reset Regeneration)
and machine operation is continued.
Can be initiated when prompted by the
engine ECU or after a minimum of 50
hours of engine operation.
For software 122-0251E and up: if
a parked regeneration is ignored, the
machine mow function (PTO) will be
