Abstract: The present invention is a trailer for the repair and construction of fences used for example, to enclose farmland or livestock on a ranch. The trailer is a fully self-contained fencing apparatus which can be conveyed by various vehicles capable of traversing the terrain to be fenced. The trailer of the present invention is particularly useful for conserving expensive, heavy-duty conveyance vehicles such as 4-wheel drive pick-up trucks since it is a fully self-contained fencing apparatus and can easily be conveyed by smaller, less expensive vehicles such as ATVs (all-terrain vehicles). The trailer includes carriers such as tool boxes, mounting posts and mounting cylinders for carrying and storing fencing tools and materials. Discs for carrying and spooling out fence wire are mounted on the trailer and can be extended outward from the trailer such that numerous lines of fence wire can be spooled out simultaneously without the lines interfering with each other.
