Fans of construction toys will love the LEGO® City Cement Mixer (60478) model building kit for ages 7 and up. This detailed concrete mixer truck with 8 rubber tires features a large drum with an Archimedes’ screw system. Kids can turn a dial to mix and dispense the LEGO cement down the adjustable chute, just like real cement pouring. This big toy truck also features a driver’s cab that tilts to allow access to the engine.
