Slow, ponderous, usual looking, yet servicing the needs of countless motorists*, road graders are always the bridesmaid when it comes to LEGO. They have appeared as B-Models several times over the years, but we don’t think that they’ve ever made it onto the front of the box. Which is shame really, as they’re more technically complex than much of what drives on the roads they help to build.

Helping to rectify this is Jundis of Eurobricks, who has built this amazing Technic Caterpillar 120M2 motorgrader with an enormous array of functions.

Pneumatics allow the front blade and rear ripper to raise and lower, whilst the middle blade can move up, down, sideways and tilt, thanks to three separate pneumatic cylinders. The model features a variety of mechanical functions too, including working steering (both via the front wheels and central articulation), plus blade turning, pitch, and lateral movement.

It’s a properly clever creation and one that’s definitely worth a closer inspection. Head to the Eurobricks forum via the link above to read the Caterpillar’s full build details and watch a video of all those functions at work.
