A backhoe has four wheels. 1, 2, 3 and 4. This part is the tractor which contains the engine. The engine gives the backhoe its power. This part is where all of the controls are, and it's called the cab. Here come some lights so the backhoe can work in the dark. The steering wheel allows the driver to turn the backhoe left and right. We'd better include a seat for the driver to sit on. And of course, we need the driver to operate it. The exhaust pipe moves hot air and gases away from the engine. Let's add some windows to protect the driver And some doors so the driver can get in and out. These are called stabilizer legs, and they help keep the backhoe steady when it's digging in the ground. Here is the backhoe and the backhoe bucket. This part is used for digging holes. This is the front loader and the front loader bucket. The front loader is really strong and can lift lots of heavy dirt and rocks. And there is the finished backhoe! Let's see it in action!
