9 MAINTENANCE
Parked Regen State - When a Parked Regen is needed,
the Regen Request light will flash and the Tier 4 Service
Message screen is shown on the LDU. Park the mower on
concrete or gravel to prevent damage to the turf.
If the REGEN INHIBITED is selected on the LDU, Turn the
ignition switch to the Off position and restart the engine.
Enter Maintenance mode (See Section 9.2). Press the
joystick forward or backward until the REGEN REQUEST
screen is shown on the LDU. Press the LDU button. The
parking brake switch must be on, the traction pedal must be
in the neutral position, the PTO switch must be in the OFF
position and the adaptive throttle switch in the Garage
Mode position. The LDU will show a instruction screen if
conditions are not met. If the condition shown is not
corrected in 5 seconds, the Regen request will be canceled.
When the REGEN REQUEST? screen is shown on the
LDU, press the LDU button to start the Parked Regen
Cycle. During the Parked Regen cycle, the PARKED
REGEN IN PROCESS screen is shown on the LDU.
During the Parked Regen, the Regen Request light will
illuminate. When high-exhaust temperatures are sensed
during Parked Regen, the High-Exhaust Temperature light
will illuminate. Do not disengage the parking brake, stop the
engine or move the mower during the Parked Regen.
If the REGEN HALTED DUE TO ENGINE SVC screen is
shown on the LDU, the Parked Regen cycle must be started
using the Kubota Diagmaster service tool.
