Title: Land clearing
Subtitle: Photograph of land clearing for the new town of Rock Gully, south of Western Australia
Date: 1959
Notes: A reinforced steel ball 8 feet in diameter and weighing 5 tons is dragged on a 200 foot chain behind two bulldozers. The chain has 2 inch links and weighs 8 tons. A third bulldozer follows the ball to add weight against particularly tough trees. In lightly timbered country the 'hi-ball' method clears 100 acres a day, in heavier timber 60 acres a day. The timber is bulldozed into windrows, left to dry for a year then then burned.
