After you know about four-wheel drive or 4WD, basically there are only four types 4WD, namely:

Part-time 4WD, when in normal conditions, this system can move with 2WD. However, if you will, the driver can move the system drive from 2WD to 4WD with the use lever or button. Even, progressively with the development of the technology at this time, the movement can be done in running condition (shift on the fly). The average strength of the machine is divided 50:50 to front and rear wheels.

Selectable 4WD, a system that is even more sophisticated. Because it gives more flexibility on the driver to select the type of booster its wheel, whether driving 2WD, full-time 4WD, even part-time 4WD in order to obtain maximum traksi.

Permanent 4WD, or in a regular full-time 4WD, on the type, the center differential automatically locks. It is easier for drivers, because there is no need to lock manually. This system can function properly in the asphalt road and in the field of mud.

Automatic 4WD, the same system with a system Part-time 4WD, but the discriminating, if the Part-time 4WD system migration done manually by using the button / lever. But on Automatic 4WD movement has been automatically can be done. That is, when in normal conditions this system can move with 2WD, however, but then the system detects the obstacles in the way that requires the use of the 4WD system. So, automatically power will be divided into the front and rear wheels with a comparison that was adjusted to the conditions of the field.
