Quad bikes are an essential part of the New Zealand dairy farmer’s modern farming world. The corrosive nature of the cow manure on the farms causes the framework of the quad bike to rust out. Some bikes are treated with a diesel and oil mixture, however this evaporates off and breaks down in approximately 3 months. Most frames rust through on the front steering wishbone where the muck has built up over the top, and the owner is therefore unaware what is happening underneath or the safety issues about to present themselves.When the wishbone finally gives way all steering is lost and the bike is off over a bank or into a drain.
