An easily portable system for extracting vehicles that have become mired in terrain such as mud or sand. A multi-purpose tool(s) is/are provided that may serve as a land-anchor, a fulcrum-lever unit, and a shovel. The land-anchor is placed in the ground and connected to the mired vehicle with a rope, with a come-along or another power source provided. Preferably, a fulcrum-lever is placed in front of the mired vehicle and the rope passes over the fulcrum-lever. so that the fulcrum-lever provides an upward force to the vehicle. When the come-along or other power source draws in the rope, the rope applies both horizontal and vertical force to free the mired vehicle. Alternatively, the system may be used without the fulcrum-lever to free lighter-weight vehicles. Because the land-anchor generally must be placed below ground level and because digging around or under the vehicle often helps to free the vehicle, the multi-purpose unit preferably may be converted into a shovel.
