The locking of the differential must be used only when it is nec- essary to make the rear driving wheels integral with each other if the machine skids or gets stuck in sand or mud. The locking is obtained by simply pressing the button (11) in 1st or 2nd gear only.
The locking of the differential is automatically disconnected when the wheels return to the normal drive. RWA31360 RWA31360
