If you have children around or – like us – messy mythical creatures, then we’ve got just the Lego creation for you! This Hovertrack Luctor 544 tractor is a brilliant model in its own right – with a working six-cylinder piston engine, remotely controlled all-wheel-drive, gearbox and steering, trailer hitch and LED lights – but what it’s towing is even more impressive…

That big red box is apparently a Schuitemaker Rapide 8400 RS forage wagon (no, us neither) which is in essence a giant carpet cleaner. It’s used for collecting mown grass via a huge spiky rotating thresher type thingumy, which is then stored for dispatching elsewhere. It’s an impressive piece of kit, and previous bloggee 896gerard has constructed a Technic version that really, truly, and brilliantly works. It might be made from Danish plastic but this model can clean TLCB office better than our vacuum cleaner.

You can the full gallery of images via Brickshelf here, but to really appreciate how good this model is you’ve got to see it in action – click this link to visit 896gerard’s MOCpages account for the full details and a video of some incredible Lego engineering…
