Power transmission
The

It has a torque converter with free-wheeling stator and automatic
direct drive clutch (Lock-up) in all gears. The machine has six
forward gears and two reverse gears.
The dropbox has a differential which distributes the torque equally
between the front axle and rear axles, which reduces tire and road
wear as well as fuel consumption. The longitudinal differential is
provided with a locking function.
ATC Automatic Traction Control automatically controls
engagement and disengagement of longitudinal differential lock
and 6x6-drive as needed.
The drive axles are provided with a differential and hub reduction
gears of the planetary gear type. All drive axles have a differential
lock.
