"We work a lot of steep virgin country that has never been cultivated. Plenty of rushes, timber etc. What we need is maximum penetration and bite, yet a weight we can still pull around the steep stuff with 200Hp. The lobe blades we run are perfect for this, they really bite in due to their shape, and track better when on steep sidelings. They take less power to pull, and seem to last for years."
