ABSTRACT:
A wire fencing tensioning apparatus comprising a generally rectangular shaped open frame carriage mounted on a standard three-way hitch on the rear of a tractor. The generally rectangular shaped open frame carriage comprises a plurality of corresponding parallel members joined at ends to form corners, which members and corners define the generally rectangular shaped open frame carriage. The wire fencing tensioning apparatus has a pair of extending hydraulic cylinders. Each of the extending hydraulic cylinders has a pulley attached to the top of the extending portion or piston thereof through each of which pulley a cable is strung. The wire fencing tensioning apparatus has a hydraulic control, the hydraulic control being capable of independently controlling each of extending hydraulic cylinders. The wire fencing tensioning apparatus has a pair of pulley-cable systems by which tension is supplied to "stretch" the wire. The pair of pulley-cable systems provide one pulley-cable system each on each of the pair of extending hydraulic cylinders. The pair of pulley-cable systems provide for tensioning two separate strands of fence wire from opposite directions as well as tensioning single strands from either direction of the wire fencing tensioning apparatus.
