One of my first micro models, spawned from messing around with a minimotor.
The tractor. Notice the "lights" and license plate.
The gear train, which powers the truck's four wheel drive.
Side view of the entire truck. I tried using an old 4x14 Technic battery pack as a trailer, so the truck would have an onboard power source, but that made it too heavy for it to haul its own weight. Alas. All the same, I like how it turned out.
