Only a sturdy concrete mixer can handle a big construction project. With the LEGO Technic Concrete Mixer Truck, you can have the best concrete in no time. Drive the truck to the right place and turn the drum to mix the concrete. Time to unload? Move the rotating drum counterclockwise to let the concrete flow out. Make sure the funnel is positioned above the place where you need the concrete, so you can immediately get on with your next building project.
