CHAPTER 3. MOWER OPERATION
91
・ Be restricted from lift up the mower deck
excessively while the mower blades are
rotating.
・
When you want to lift up the mower deck high,
switch off the PTO switch. Never attempt to
switch on the PTO switch while the mower
deck is lift up high.
・ Before starting to mow, make sure that the lift
cylinder is set properly.
・ Whenever you encounter with any trouble
of the front mower, ask your dealer for repair
immediately
・Be
sure to start moving at sufficiently low
speeds and increase travelling speed gradually.
WARNING:
・As soon as the PTO switch is pushed
to the ON position, the mower blades
start rotating and eject cut grass or
stones through the discharge opening.
Consequently, before operating the PTO
switch, make sure that there is no people,
animals, or physical properties like
buildings, cars, etc. within a range where
ejected grass or stones may reach.
・The mower blades should be turned only
on turf or grassland with the mower deck
lowered.
i. Turn the throttle lever to the high speed position to
raise engine speed.
j. As the HST forward travel pedal is depressed
gradually, the front mower starts to travel.
IMPORTANT: The radiator screen should be kept clean.
Never keep on operating with clogged screens, or the
engine may be overheated, which may result in engine
seizure.
k. The front mower is equipped with a system called
"Up-stop" device, which stop the mower blades
when the mower deck is lifted up while the front
mower is travelling on rugged terrain with the
mower PTO.
DANGER:
・The up-stop device is installed to prevent
accidents. Never attempt to activate the
system by operating the mower lift lever.
・The mower blades of the mower deck
stopped by this device are subject to
turning very slowly even when the mower
deck is lifted up, which is very dangerous
and may shorten the service life of the
drive shaft.
