DIFFERENTIAL LOCKING
WARNING
q
This device can be used only with the 1
st
, 2
nd
or 3
rd
gear
engaged, either forward or reverse.
The differential must be locked with the machine at rest
or at very low speed.
q
The release of the differential takes place automatically
when the axles transmit the same load as before, that is,
when the two-wheel drive is engaged.
This device is useful when the machine must work on muddy
or loose ground or when the machine gets stuck in mud.
The differential can be locked by pressing the button (1) posi-
tioned on the front bucket control lever, with the rear wheels at
rest.
In exceptional cases the locking of the differential can be per-
formed even with the machine running straight at very low
speed, that is, with the rear wheels turning at the same speed.

icy, gravelly ground, on slopes and in any situation in which it
is difficult to move the machine.
The four-wheel drive must be used even when the machine is
provided with optional equipment to be employed as snow-
plough.

The four-wheel drive is automatically engaged when the
machine brakes and only in 4
th
gear.
