Surface Resistance When Winching

May 12th, 2013 | By | Category: Tow Tip

Surface conditions can add significantly to the amount of resistance to overcome when winching a vehicle. Winching a 4,000-lb. vehicle over a hard surface will require about 400 pounds of effort, while winching over grass or gravel will require approximately 1,320 pounds of effort. Mud or soft ground can increase the load resistance by up to 300 percent of the vehicle’s weight.
