Wheeled grail

The wheeled grail is a large, heavier ploughing machine that It required a considerable force of animals to drag it, since It was used to make a lot of fallow. It was formed by a rectangular structure which was held on two wheels. It consists of the following parts: poles for the branches, handlebar, two blades, the tree, the punch, the estrinquet and a regulator to raise or lower the wheel axis. For its elaboration, a much more complex technology than small rotating was required. Generally, its construction was industrial.
