Mouldboard+Plow

The Mouldboard Plow was made in the 18th century. It was used to help with agriculture. Besides moving the soil, it turned the soil up and over, bringing nutrients for the growth of plants. When dragged through a field the coulter cuts down into the soil and the share cuts horizontally from the previous furrow to the vertical cut. This releases a rectangular strip of sod that is then lifted by the share and carried by the mouldboard up and over, so that the strip of sod (slice of the topsoil) that is being cut lifts and rolls over as the plough moves forward, dropping back to the ground upside down into the furrow and onto the turned soil from the previous run down the field. Each gap in the ground where the soil has been lifted and moved across (usually to the right) is called a //furrow//. The sod that has been lifted from it rests at about a 45 degree angle in the next-door furrow and lies up the back of the sod from the previous run. As you can see it is very similar in style to the way that the Oliver Plow is.
