Better winching
The easiest way to increase pulling power is to use a snatch block. For those of you who aren't familiar w/a snatch block, it is merely a large, heavy duty pulley secured to your winching point. You run the winch cable to & through the pulley & back to your vehicle doubling the pulling power. If you are winching to a tree, be sure to use a strap around the tree so it will survive after you leave.
