A bulldozer is often a child's first construction toy. This book shows the real machine hard at work, carving roads, clearing land, ripping rock, demolishing buildings, mining, quarrying, plowing snow and working for the military. This book describes the many different blades and attachments and how a bulldozer's design keeps it from falling over or tipping backward. The photographs also show the many sizes of bulldozer, from the mammoth crawler to the (relatively) tiny calf bulldozer used in mining.
