Rred, first of all God bless you. If it wasn?t for brave people like you we would be living in a very different world today.
In 4H the vehicle basically works as an open diff system with only the traction control to help it regain traction. With the locked central diff the power is split evenly on both front and rear axles and even if one or both wheels on one axle spin the other axle will still have power to move the vehicle. If you also lock the rear diff it will do the same with the rear axle. Even if both front wheels and one of the rear ones spin the other one will have power to move the vehicle. The ideal setting would be to also have a front locking diff. I think there are aftermarket ones available.
That?s how I think it works, if I?m wrong please correct me.
