The Mighty Backhoe is the truck-of-all-trucks. It digs like an excavator and dozes like a bulldozer. That's why it's the favorite of Billy and all the kids in his neighborhood!

Sam drives the mighty tractor trailer with his bulldozer on top to a busy construction site where they are going to help build a new home.

Mike's Mighty Mixer mixes and pours cement at busy construction sites.

Alex watches the construction of a skyscraper on his block, from the day the empty lot is measured until the dedication of the new building and its adjacent playground.

Text and illustrations describe a variety of Tonka toy trucks and what these trucks can do.
