10. Machines Go to School

How do you think earth-moving machines learn to do their jobs? They go to school! It's not easy for Backhoe to dig a tidy trench, and Bulldozer has a difficult time buillding an earth ramp. The Graders, Front-End Loaders and Excavators all need special instructions to do their jobs. And watch out for the Mini-Dozers - they have a good time learning their jobs. Even machines have fun at school.
