ABSTRACT:
An assembly for creating furrows in a freshly plowed field. The furrows, two to three feet apart, are usually created in the fall and are useful for retaining moisture in the soil during the winter months and are helpful in preventing soil erosion by the wind. The furrowing assembly is detachably mounted on a mulcher bar assembly which is mounted to a moldboard plow. The mulcher bar assembly includes an elongated bar having several chisel-type field cultivators downwardly extending in a soil-engaging position. The orientation of the mulcher bar may be reversed so that rod-like teeth members extending therefrom are in a soil-engaging position for mulching in the spring. Thus, depending upon the orientation of the mulcher bar, the apparatus may be used for either mulching or furrowing.
