A portable windbreak may be operably attached to a vehicle for advancement in a forward direction. The portable windbreak includes a wheeled chassis and a set of panels. The wheeled chassis includes an elongated frame and a ground-engaging transport wheel operable to support the frame above ground, with the frame extending longitudinally along the forward direction to at least partly define a storage area. The set of panels is removably supported by the frame and extends longitudinally along the frame in a stored condition. The set of panels is shiftable between the stored condition and a deployed condition, in which one or more panels of the set extend outside of the storage area to form a windbreak wall.

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 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.

A modular livestock fencing system includes a plurality of collapsible modular fence units configured to house and control egress for livestock. Each collapsible modular fence includes two posts perpendicular to the ground and a plurality of rotatably supporting members connecting the two posts such that each rotatable supporting member can be rotated in a scissor motion to bring the two posts toward one another into a fully collapsed position where the posts are substantially in contact with one another or an expanded configuration where the posts are displaced from one another in a fully extended position. The system may include a locking mechanism which locks the supporting members at the fully extended position. The system includes a plurality of connection elements located on the two posts that are configured to connect one modular fence unit with one or more additional modular fence units.

A portable fence reel has a reel spool, and a frame including at least one arm, where the reel spool is rotatably mounted to the at least one arm. The fence reel also has a crank shaft, where rotation of a crank shaft results in rotation of the reel spool, and a winding handle. An automatic engaging mechanism includes a coupler rotationally fixed to the crank shaft, and a clutch portion configured to be driven by the winding handle and, in use, move along a longitudinal axis of the crank shaft to engage or disengage with the coupler.

A herd management system for monitoring and managing the movements of animals within a herd comprises a user interface for defining one or more virtual fences for each to comprise a paddock, a plurality of wireless tags affixed to the monitored animals, and a network server for managing communications between the user interface and wireless communication with the tags. The tags include devices for stimulating the animal to move as desired by the herd management system, including staying within a paddock or moving from one paddock to another as guided by the system.

In general, one aspect disclosed features an apparatus comprising: a mobile agricultural structure; and at least one wheel assembly mechanically coupled to the mobile agricultural structure, wherein each wheel assembly comprises: two or more wheels, a motor disposed between two of the wheels, a drive transference mechanically coupled to the motor and the wheels, wherein the motor is configured to turn the drive transference and the wheels together, a housing, wherein the motor is enclosed by the housing, and a rotatable mechanical linkage mechanically coupled between the housing and the mobile agricultural structure.
