Having to remove 5 miles (8 km) of fence we needed to be able to roll up the wire quickly. We originally built the wheel that holds the wire to fit on our post hole auger drive, which worked reasonably well but did not give us the control we wanted. This system now works very well. We directly drive the wheel with a 1000 RPM hydraulic motor (because we had it in our possession), we put a flow control into the line to slow it down a little. To keep tension on the wire we tie a Quad motorcycle to the other end of the wire for the last 500 feet the person on the Quad needs to apply some brakes to keep the tension on the spool too keep the wire roll nice and tight so it will not unravel when taken off. If we plan on reusing the wire we roll up one wire at a time, if we do not wish to reuse it we roll up all the strands in one go. A wire that is more then 1/2 mile long is harder to roll up because it has too much drag and sometimes will not hold together.
This attachment was built for our BobCat and is part of our post pulling system.
Notice the cone shape that the wire is rolled onto, this is so that the wire roll will slide off easily.
A bar is needed to nudge the wire roll off the cone. If the wire is rolled tightly it will stay together just as it comes off the cone. This spool is 1/2 mile (0.8 km) of barbed wire.
