On May 15th, the "San Isidro Labrador" festival, many people came to the town for the carts blessing. Pedro also took his cart, but had bad intentions, stopping his wagon very close to the door of the church, far from the other carts.

When the priest asked Pedro to align his cart with the others, then Pedro replied "I don't want tour blessing, my cart is already blessed by the Devil" and he tried to enter his cart to the church, but the oxen resisted to enter; rather they escaped from the yoke and cart rolled street down with Pedro.

The priest said then: "You will wander forever with your cart".

The oxen was saved from the curse, because they refused to enter the church.

According to the legend, since then the cart already blessed by the devil, wanders without oxen pulling it, causing horror with the noise of its wheels.

According to some villagers, the cart without oxen wanders through towns where there are no love nor harmony among its inhabitants, always after the midnight.
