• Main functions:
  • Loosening and turning the soil
  • Mixing fertilisers or manure with soil
  • Removing weeds
• Usually made of wood, but modern ploughs are made of iron

Parts of a Plough

• Ploughshaft: Long wooden part
• Handle: Used by the farmer to control the plough
• Ploughshare: Strong triangular iron blade that cuts the soil
• Beam: Attached to the necks of bulls

 One farmer and a pair of bulls can easily operate a plough.
 Wooden ploughs are now being replaced by iron ploughs.
