Abstract
One embodiment of a remotely controlled apparatus for selectably admitting a large animal into and then selectably releasing the animal from a livestock chute uses the weight of the animal as its primary energy source for opening and closing the entry and exit gates. The livestock chute has a linking mechanism for communicating with the entry gate, the exit gate, a moveable floor, and a biasing force wherein the weight of the animal is used to overcome the biasing force to open the entry gate and to store energy that can be selectively activated to open the exit gate on the livestock chute.
