Backhoes

Digging machines fascinate many young children. Backhoes are extra-large machines that draw earth backward instead of lifting it forward like shovels or other digging machines do. They can be found at many work sites, building roads and digging the foundations for people's homes and other buildings, even skyscrapers. This book explores the different types of backhoes and how they've helped people do jobs for many years. Full-color photographs of backhoes and workers in action help readers understand just how these extra-large machines get the job done.
