Bulldozer

My three-year-old son is fascinated by earth moving equipment. He wants to know EVERYTHING about how they work and what they do. This book does not disappoint. It's heavily detailed, and extremely informative about all sorts of equipment (not just bulldozers). I found that taking a cross-section out of a ship we built from legos helped him understand what was happening in the pictures better. The text can be a bit boring, and by around the hundredth reading it can get irritating. But reading different sections of the book keeps it fresh, and the amazing amount of genuinely interesting information packed into this little book (and subsequently into my son's little head) makes it all worthwhile. The glossary in the back makes all the concepts involved really understandable, even to me, my son's non-technical mom. If your child is into diggers and dumpers, this book is a must.
