Deadman Anchor Depth Calculator — How Deep to Bury for a Safe Pull
A shallow deadman anchor will pull right out under winch load. Calculate the depth before you’re stuck relying on it.
Enter your vehicle weight, soil type, and anchor board dimensions. The calculator returns the required burial depth for a safe static anchor under recovery load.
A deadman anchor that fails under load can snap a winch line or flip the anchor vehicle. Burial depth is a function of soil resistance and recovery force.
