(2) Clutch pedal (PSS)
 This pedal is used to engage or disengage the
engine power for engine start, transmission shift
and stopping tractor.
 To disengage the clutch, depress the clutch
pedal fully. If PTO select switch is placed on
“AUTO” and clutch pedal is fully depressed, the
PTO shaft will be stopped.
 If the clutch pedal sensor has trouble or an error,
the engagement or disengagement of the clutch
is NOT smoothly operated and it’s
corresponding error code is displayed on the
instrument panel with intermittent alarm.
In this case, the tractor can be moved by using
the power shuttle lever. After moving the tractor
to safe area, contact your authorized dealer for
check.
 To protect the radical wear of the clutch, if the engagement time is prolonged over 6 seconds, an
alarm will happen, and if prolonged over 8 seconds, the clutch will be disengaged completely. In this
case, operate the shuttle lever again from neutral position or depress the clutch pedal fully one time
to recover the clutch system.
 When driving the tractor on a slope, especially with heavy loaded implements, select a suitable
driving speed to start the tractor. Appling high engine rpm and long-lasting clutch engagement at a
high transmission gear ratio can cause serious damage to clutch pack.
► Depress the clutch pedal quickly and fully, and release it slowly.
► When starting the engine, depress the clutch pedal fully. If not, the engine may not
start due to interlocking of the start safety switch for user’s safety.
► Do not ride your foot on the clutch pedal while driving.
► If the engagement time is prolonged over 8 seconds on a slope, the engine power
will be cut off by safety interlock system. It means that tractor can slip down and
your special care must be taken.
At this time, press the brake pedals immediately and recover the power shuttle
system by depressing the clutch pedal fully or Re-operating the shuttle lever from
the neutral position.
