Project 42213 Unimog Mods and Attachments – 25/08/2025 – Road Roller

One of the great things about the LEGO Technic 42213 Unimog is how adaptable it is for attachments, and today’s project is another example of this flexibility – the Road Roller attachment.

This attachment is designed to tow behind the Unimog using the rear tow bar (added in my previous update). It features two pairs of wide wheels placed side by side, giving it a proper roller look. The doubled tyres give it enough weight and surface area to really resemble how a roller would press down and smooth surfaces in real life.

The build is simple but effective:

• A long tow arm connects securely to the rear tow hitch.

• Two axle beams hold the paired wheels in place, providing a sturdy base.

• The attachment is reinforced with lift arms and connectors to keep everything aligned and stable while being pulled along.

From a play and display perspective, it works really well. The roller follows behind smoothly, and the paired tyres give a realistic rolling effect. It’s also modular, so it can be easily detached and swapped out for other tools when needed.

This attachment opens up more possibilities for construction-style play with the Unimog – you can imagine it grading a dirt road, flattening gravel, or finishing off a construction site.

Another small but satisfying upgrade to the ever-growing list of attachments for Project 42213!
