LEGO TECHNIC 42129

Celebrate a hero of the construction world as you build a replica version of the biggest Cat dozer with this LEGO Technic App-Controlled Cat D11 Bulldozer (42131) kit. This large set lets adults enjoy quality ‘me time’ focusing on their passion. Just like the real Cat bulldozer, this model is built in modular sections.

With many authentic features and functions packed into this model, there’s lots to discover.

Use the CONTROL+ app to operate and explore this heavy-duty machine. The app delivers realistic movement as you raise, lower and tilt the blade or raise and lower the ripper and ladder.
