A large animal trap (especially for wild hogs) that is easily moved by a single individual and takes only ten minutes to unload and set up and walk away. It is approximately 7½′ diameter across the center allowing a trapper to potentially catch a whole herd at once, but overall it is still light enough for a single individual to pick up and roll anywhere owing to its approximately circular drum shape. Overall, the trap includes 750+ welds making the trap exceedingly strong for its weight and size. The trap further includes triple offset walls to help keep all trapped animals in. In use, the trap is firmly secured to the ground by a chain and allows nothing to get out except turkeys which can fly out the escape hole in the top. It is easy, fast and fun to set the trap. A user only needs to tie the rope on the door and set the pins to engage the ground and suspend the door in the open position using the rope. A user then pours corn in and waits until the hogs come into the trap. When the wild hogs or other large animals in the trap root up the pins in the ground, the door drops and locks shut and you keep everything that came into the trap. Nothing gets out unless it flies. It is a fully assembled trap with no assembly required post purchase.
