2.2. AUTO / 4WD CHANGEOVER LEVER (4WD
LEVER) SFH240FH
With this lever, 2WD/4WD automatic change-over and
permanent 4WD is selectable.
4
:
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
automatically during operation on a level ground, so the
lever operation 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 streight.
WARNING:When operating the front mower
on a slope, be sure the 4WD lever is locked
in the 4WD position from the reasons
mentioned below:
In the AUTO position the mechanism shifts to 2WD
automatically when the peripheral speed of the front
wheels exceeds that of the rear wheels, which means
loss of rear wheel driving power.
For example, when moving uphill if the front wheels
slip, the mechanism stays in 4WD. But moving downhill
if the front wheels slip and lose grip, and begin to slip
down the slope, it shifts to 2WD, that is, braking effect
of the HST unit is lost, which means loss of front mower
control.
From another point of view, when you try to turn the front
mower on a slope, rear wheel driving power is lost and
the front mower may slip down the slope, which is also
very dangerous.
