Abstract: A coupling assembly for use with a tractor having a three point mounting hitch assembly having two extension legs telescopically retained by two generally vertical sleeve members slanted towards each other and two lateral extension arms telescopically retained by a cross sleeve member, wherein the lateral extension arms can be extended or retracted and wherein the extension legs can be extended or retracted to alter the relative positions of an upper hook and two lower hooks.

Abstract: A fencing wire unwinder and tensioner for constructing wire fences, the apparatus comprising a carrying platform for spools and rolls of fencing wire, whereby the wire is unwound and tensioned in a single operation for attachment to the preset posts of the fence. The device may be adapted for barbed wire only, woven wire only, and chain link only, or barbed wire along with either of the latter. Spools of barbed wire strand and/or rolls of woven or chain link wire are carried rotatably on a platform, the wire being fastened to the fence and unwound therealong as the platform is carried along the fence line by the vehicle. The wire unwound from the roll is tensioned by braking band before leaving the platform. Helpers follow the platform and attach the fencing in tensioned condition to the preset line of posts.

Abstract: A fencing wire unwinder and tensioner, and method, for constructing wire fences, the apparatus comprising a carrying platform for spools and rolls of fencing wire, whereby the wire is unwound and tensioned in a single operation for attachment to the preset posts of the fence. According to one embodiment, the device is adapted for barbed wire only; to another embodiment, woven wire only; and a third embodiment both barbed and woven wire. Spools of barbed wire strand and/or rolls of woven wire are carried rotatably on a platform, the wire being fastened to the fence to be unwound therealong as the platform is carried along the fence line by the vehicle. As the wire is unwound from the roll it is tensioned before leaving the platform by a braking disc (barbed wire) or an elongate braking drum (woven wire). A braking band is provided for each of the drum and the discs so that the wire is adjustably tensioned as it is drawn from the apparatus.
