Portable Cattle Corrals are self-contained, wheeled tow-behind units of gate-like panels pulled by tractor or pickup truck to where needed for sorting or working range cattle. Once in place, they can be set up rather quickly because all the panels have wheels to roll them into position. For some units, solar-battery-powered electric-over hydraulic jack eliminates the need for lifting. The panels are connected by a pinning system and can be folded back flush with each other when ready to move the unit without having to unpin. Depending on model, a corral may hold up to 500 animals and can be configured many different ways, allowing for multiple pen options. Available accessories often include battery-charging unit, loading chute, head gate, extra-long gates, frame gate for sorting, etc.
