What It IsFor kids who are ready to graduate to more advanced building systems, there is LEGO's Technic line. Technic's interconnecting rods and parts let kids create more advanced models with more complex moveable parts, such as machines with wheels, in addition to the simple brick-building properties of LEGO.
No logging job is too big for the Tractor with Log Loader. After building, use the control knob to steer the tractor and unhitch the log loader trailer. The two pneumatic valves operate the fully articulated crane arm and grasp logs with the working grabber. The set includes step-by-step instructions to rebuild the tractor into a log handler.
This 525-piece set is best for advanced builders who are familiar with the Technic system.
