Even if an ATV possesses four-wheel drive it is still possible to get stuck in a situation you cannot ride out of. In this instance a winch will come in very handy. This device is attached to the front of an ATV and possesses and electric motor capable of pulling an ATV out of essentially any situation.
A cheaper alternative to a winch is a tow rope. However, in order to pull an ATV out of a precarious situation with a tow rope another vehicle will be necessary. If an ATV is stuck in an area that a pickup truck cannot reach, another ATV will be necessary to utilize a tow rope. This is one of several reasons it is a good idea to ride with a buddy or to always ride with a group of other riders.
