Los yugos con que se unce el ganado vacuno de labor son aperos muy antiguos e imprescindibles en la agricultura tradicional. En Castilla y León, como en la mayor parte de la Península Ibérica, se emplea el yugo cornal, que presenta una rica tipología geográfica, con variantes funcionales dentro de cada tipo.

The yokes for the cattle used in farming (cows and oxen) are ancient yet essential implements for traditional agriculture. In the region of Castille-Leon, as in most other areas in the Iberian Peninsula, farmers use a kind of yoke which is tied to the horns of the animals. This kind of yoke presents a rich variety of local types, and functional variants within these types, as a result of its wide geographical distribution.
