The portable livestock corral broadly includes a chassis and opposed sets of corral panels. The chassis includes an elongated corral frame extending longitudinally along the forward direction. The opposed sets of corral panels are positioned to extend longitudinally along respective sides of the corral frame in a stored condition, with the corral frame configured to removably support the opposed sets of corral panels when the corral is advanced in the forward direction by the vehicle. The chassis further includes a shiftable rack supported by the corral frame and configured to removably engage and support at least one of the opposed sets of corral panels in the stored condition. ## Claims ### Claim 1 A portable livestock corral configured to be operably attached to a vehicle for advancement in a forward direction, said portable livestock corral comprising: a chassis including an elongated corral frame extending longitudinally along the forward direction; and opposed sets of corral panels positioned to extend longitudinally along respective sides of the corral frame in a stored condition, with the corral frame configured to support the opposed sets of corral panels when the corral is advanced in the forward direction by the vehicle, said chassis further including a shiftable rack supported by the corral frame and configured to removably engage and support at least one of the opposed sets of corral panels in the stored condition, said shiftable rack including upper and lower rack arms receiving therebetween said at least one of the opposed sets of corral panels in the stored condition, with the shiftable rack engaging said at least one of the opposed sets of corral panels and restricting lateral movement thereof out of engagement with the shiftable rack, said upper and lower rack arms being shiftably attached to the chassis at rack pivot joints and having unsupported ends positioned outboard of the rack pivot joints in the stored condition, said upper and lower rack arms being spaced vertically and removably connected relative to one another by a connection joint adjacent the unsupported ends, with the connection joint cooperating with the upper and lower rack arms to restrict relative movement between the upper and lower rack arms. ### Claim 2 (depends on 1) The portable livestock corral as claimed in claim 1, said upper and lower rack arms being pivotally attached to the corral frame. ### Claim 3 (depends on 2) The portable livestock corral as claimed in claim 2, said upper and lower rack arms being pivotally attached to the corral frame at respective pivot joints that permit the upper and lower rack arms to pivot independently of one another. ### Claim 4 (depends on 1) The portable livestock corral as claimed in claim 1, said upper and lower rack arms each including a horizontal arm and a gusset. ### Claim 5 (depends on 4) The portable livestock corral as claimed in claim 4, said gusset of the upper rack arm being located above the horizontal arm of the upper rack arm, said gusset of the lower rack arm being located below the horizontal arm of the lower rack arm. ### Claim 6 (depends on 4) The portable livestock corral as claimed in claim 4, said horizontal arms of the upper and lower rack arms being substantially parallel to one another. ### Claim 7 (depends on 4) The portable livestock corral as claimed in claim 4, said corral panels each including multiple laterally-extending rows of cross members, said corral panels being configured so that upper and lower rack arms are spaced to receive a plurality of rows of cross members therebetween in the stored condition. ### Claim 8 (depends on 1) The portable livestock corral as claimed in claim 1, said shiftable rack including an upright connector pin that removably engages the upper and lower rack arms to form the connection joint. ### Claim 9 (depends on 8) The portable livestock corral as claimed in claim 8, said upper and lower rack arms including fixed sleeves adjacent the unsupported ends, said connector pin being slidably received by the fixed sleeves so that the connector pin and fixed sleeves cooperatively restrict relative movement between the upper and lower rack arms. ### Claim 10 (depends on 1) The portable livestock corral as claimed in claim 1, said shiftable rack defining a lateral rack length dimension that ranges from about thirty-six inches to about sixty inches. ### Claim 11 (depends on 1) The portable livestock corral as claimed in claim 1, said corral frame including a spine extending longitudinally along the forward direction and at least partly defining opposed storage areas to receive corresponding corral panels. ### Claim 12 (depends on 11) The portable livestock corral as claimed in claim 11, said portable livestock corral defining a maximum corral width dimension and said spine defining a maximum spine width dimension, with a ratio of maximum spine width dimension to maximum corral width dimension being less than about 1:5. ### Claim 13 (depends on 12) The portable livestock corral as claimed in claim 12, said maximum corral width dimension being greater than about one hundred inches. ### Claim 14 (depends on 11) The portable livestock corral as claimed in claim 11, said spine defining a maximum spine width dimension that is less than about twelve inches. ### Claim 15 (depends on 11) The portable livestock corral as claimed in claim 11, said opposed sets of corral panels presenting a plurality of corral panels on respective sides of the spine, each of said plurality of corral panels on respective sides of the spine defining a corresponding folded panel width dimension, with a ratio of maximum spine width dimension to folded panel width dimension ranging from 1:4 to about 1:10. ### Claim 16 (depends on 15) The portable livestock corral as claimed in claim 15, each of said plurality of corral panels ranging from about ten corral panels to about eighteen corral panels, stacked alongside one another in the stored condition. ### Claim 17 (depends on 1) The portable livestock corral as claimed in claim 1, said corral frame including a spine extending longitudinally along the forward direction and at least partly defining opposed storage areas to receive corresponding corral panels, said chassis including a ground-engaging transport wheel operable to support the corral frame above ground, with the transport wheel being longitudinally spaced from the storage areas. ### Claim 18 (depends on 17) The portable livestock corral as claimed in claim 17, said opposed sets of corral panels each being shiftable into and out of a deployed condition, in which one or more corral panels of each of said opposed sets extend outside of the respective storage area to form an enclosed livestock pen. ### Claim 19 (depends on 1) The portable livestock corral as claimed in claim 1, said opposed sets of corral panels each including a series of corral panels pivotally attached to one another in series and configured to be folded into and out of at least partial registration with one another.
