The Wire Tensioner is a great way of pulling sheep wire straight and surprising strains can be achieved using your quad, also with the 2 post holders front and back filled with posts or coils of wire add extra weight which increases traction allowing extra strain to be accomplished. Another time saver.
Good tyres (Bear Claw) on your quad is a must if pulling wire with the Wire tensioner as grip is the key to acceptable strain, and also pull with no less than a 500cc quad that has a low gear box. No more than 50 metres should be pulled at anyone time as, remember your pulling wire with a quad not a heavy tractor. Always fence down the hill as the gravity will be to your advantage, common sense goes along way when using these attachments.
