The LEGO Technic Heavy-Duty Bulldozer is a 195-piece construction set designed for builders aged 7 and up. The completed model measures 3 inches (8 cm) high, 4 inches (10 cm) long, and 3 inches (8 cm) wide. It features working treads that allow the bulldozer to roll smoothly when pushed. The blade can be raised and lowered using a control element on top of the vehicle, mimicking the functionality of real construction equipment. This set serves as an introduction to engineering concepts through its realistic movement and mechanical functions. The building experience and play features make it suitable for children interested in vehicles and construction themes. The set can be used as a standalone play item or combined with other LEGO Technic models.
