Open Source Tractor
From P2P Foundation
= OSTrac is an open source tractor/ loader. It is an articulated tractor that steers by bending in the middle. It also has a flexible coupling between the front and back, so that the wheels stay on the ground at all times.
A work in progress at Open Source Ecology
