Charlie White, ranch manager of Pat Welder Ranches, Victoria, Texas, needed something other than a permanent cattle guard to separate his pastures. So he developed an electrified cattle guard. The guard uses electricity from the connecting fenceline and allows trucks and machinery to safely cross over while keeping cattle out. Mr. White says that it doesn't take long for cattle to learn that the guard works on the same principles as an electric fence.
The guard has six connecting wires placed 2 1/2 inches off the ground. The wires are connected at one end with eye bolts through insulated timber to keep it from grounding out. The other end has springs connected to the insulated timber and hot wires that allow vehicles to cross over without breaking down the wires.
