Abstract
A portable livestock corral is configured to be operably attached to a vehicle for advancement in a forward direction. The portable livestock corral broadly includes a wheeled chassis and opposed sets of corral panels. The wheeled chassis includes an elongated corral frame and a pair of ground-engaging transport wheels shiftable relative to the corral frame and operable to support the corral frame above ground. The opposed sets of corral panels are removably supported on the corral frame and are configured to be advanced with the corral frame in the forward direction by the vehicle. The wheeled chassis further includes a pair of spindles rotatably receiving the pair of transport wheels and a suspension. The suspension is configured to shiftably support the spindles and transport wheels relative to the corral frame. The suspension includes a torsion assembly with a pivotal torsion arm attached relative to at least one of the pair of spindles, with part of the torsion assembly configured to resiliently flex to permit shifting of the torsion arm and the transport wheels.
