Today’s blog post is brought to you by the letter ‘T’. Plus the Elves are learning about alliteration, which means that we have not one but two Technic tractors to show you.

They’re both remote control too, which also meant that we had something of an Elven showdown in the corridor this morning. Unable to squash any of their colleagues due to their finds herculean slowness, each Elf decided that the next best route to carnage was to turn their respective machines on one another. Cue the slowest vehicular joust in history, at the end of which the tractors calmly bumped into one another and the Elves at the controls left in disgust.

Well they may not be impressed, but we are, as each build is a masterclass in Technic engineering. Above is newcomer Brick_Sticker’s enormous Case 620 HD, driven by an XL motor and featuring an unusual (but very clever) pneumatic articulated steering mechanism, with an on-board compressor powered by a Medium motor providing the air pressure. Another Medium motor drives a power-take-off, and there are four pneumatic lines where tools could be attached.

It’s a spectacular machine and well worth your click – you can check out all the images and details via both Eurobricks and Brickshelf.

The Case’s gladiatorial opponent in the corridor joust comes from previous bloggee Damian Plesniak, and if anything it’s even slower. Driven by twin Medium motors, Damian’s tracked mini loader features skid-steering, plus a tilting and raising bucket powered by a third Medium motor and an XL.

It works a treat too, and you can see all of the (brilliantly taken) images on Flickr here, plus you can watch a video of the loader in action by visiting the Eurobricks discussion forum.
