DISC PLOUGH

• Disc plough is used in the following conditions:
  • Clayey and sticky soils where mould board plough does not scour well.
  • Soil having hard pan or plough sole below regular ploughing depth.
  • Dry and hard land which are difficult to plough with mould board plough.
  • Stony and stumpy soils which are likely to cause damage to mould board plough.
• Disc plough is capable of ploughing at more depth than mould board plough. Disc plough does not completely invert the soil. A disc plough consists of 2 or 3 discs, cross shaft, frame, disc bearing brackets, scrapers, land wheel and furrow wheel. Diameter of steel concave discs varies from 600 to 900 mm.
• Furrow wheel is attached at the rear of disc plough. This is provided to counter act the soil side thrust force exerted on the discs during ploughing. Scrapers are used to keep the disc surfaces clean. Discs are set at an angle to the direction of travel and also to vertical line.
