CHAPTER 5. CONTROLS AND METERS
2. STEERING POST
2.1. THROTTLE LEVER
With this lever, the engine speed is controlled.
: LOW: Shift (Pull) the lever towards the “turtle” mark,
the engine decelerates.
: HIGH: Shift (Push) the lever towards the “rabbit”
mark, the engine accelerates.
This front mower is equipped with Auto throttle system, it
raises up engine speed by depressing HST forward/
reverse travel pedal.
IMPORTANT: Don’t use Auto throttle for mowing opera-
tion. Set rated engine speed by hand
throttle lever.
2.2. AUTO / 4WD CHANGEOVER LEVER (4WD LEVER)
With this lever, 2WD/4WD automatic change-over and
permanent 4WD is selectable.
: 4WD PERM: Shift (push) the lever forward to
engage permanent 4WD mode.
4WD AUT: Shift (pull) the lever rearward to engage
AUTO 4WD mode.
In AUTO 4WD mode, 2WD and 4WD is selected automati-
cally during operation on a level ground, so the lever oper-
ation is not required.
When operating on a slope, shift the changeover lever to
the 4WD position without fail.
IMPORTANT: Be sure to shift the 4WD lever to the
“AUTO” position when operating on level
ground, as level ground operation with the
4WD selected leads to a larger turning
radius and may cause turf damage.
IMPORTANT: When shifting the 4WD lever, slow down
the travelling speed below 1 km/h and
make the machine go straight.
WARNING: When operating the front mower
on a slope, be sure the 4WD lever is locked in
the 4WD position from the reasons men-
tioned below:
In the AUTO position the mechanism shifts to 2WD auto-
matically when the peripheral speed of the front wheels
exceeds that of the rear wheels, which means loss of rear
wheel driving power.
