A coulter attachment is used with?

  • A.Disc harrow
  • B.Seed drill
  • C.MB plough
  • D.Subsoiler

Answer: C

A coulter is used with the MB plough (mouldboard plough).

A coulter is a sharp vertical knife or rolling disc mounted ahead of the plough bottom. It cuts the furrow slice vertically from the unploughed land and slices through trash and roots, which gives a clean furrow wall and less draft. Rolling coulters and knife coulters are attachments of the mouldboard plough.

A disc harrow cuts with its own discs and needs no coulter. A seed drill uses furrow openers, and a subsoiler uses a narrow shank and point to break hardpan.
