The disc harrow has become a fixture on nearly every farm since its introduction many years ago. When it’s doing its job, a disc should size residue to manageable
pieces, blend residue into soil to speed up decomposition and deter erosion, break up clods and level the field.
To do its job right, a disc needs enough weight to cut tough residue. It also needs gang placement to leave a uniform surface, allowing material to flow through the
tool rather than building up. A good disc harrow is easy to keep balanced, easy to use and easy to maintain.
