The Machinery Series is another nice extension to the CREATIVE BUILDER line, which places emphasis on the construction of diggers, cranes and trucks, some of the most favorite play themes of 6 to 9 year old youngsters! The line consists of four different pack options, each one containing instructions for three different models. Children can build iconic machines such as a Backhoe Loader, a Telescopic Handler and a Skid Steer Loader. The larger set also includes a motor which brings the Machinery models to life.
