Moon Mining: Harvester

Two things inspired this monstrosity, one was the movie Moon where they have set up a mining operation on the moon to harvest Helium 3 (needed for fusion reactors) and the announcement from Deep Space Industries (D.S.I) that they are going to start mining asteroids and the Moon in the near future.
I thought that seeing as it's on the Moon you wouldn't really need to worry about things like pollution and noise so you can build them big and loud. So as part of a running series about strip mining the Moon bare I give you the H.H.P (Heavy Harvester Platform) this one is called Leviathan and is number 2 of a fleet of 10 that slowly move over the surface of the Moon at about 3 mph and rip up the surface extracting the Helium 3 in its on board processing plant. Smaller transports take the Helium 3 to nearby depots where it's fired at the Earth in large containers.

It's damn dirty as behind each machine is several miles of dust that takes some time to settle and also it leaves behind a trench about 20 metres deep, but damn does it look awesome... Also it has no brakes.
