6. Mouldboard
Types of mould board

8. Plough accessories
Jointer
small irregular piece of metal of shape of an ordinary plough
bottom.
purpose is to turn over a small ribbon like furrow slice directly
in front of the main plough bottom.
Coulter
to cut the furrow slice vertically from the land ahead of the
plough bottom.
It cuts the furrow slice from the land and leaves a clear wall.
It also cuts trashes which are covered under the soil by the
plough.

9. Rolling type disc coulter
Sliding type knife coulter
Jointer Coulter

10. Gauge wheel
auxiliary wheel maintain an uniform depth.
Land wheel
wheel of the plough which runs on ploughed land.
Front furrow wheel
front wheel of the plough runs in the furrow.
Rear furrow wheel
rear wheel of the plough which runs in the furrow.

11. Adjustment of mouldboard plough
(i) Vertical suction and (ii) Horizontal suction.
Vertical suction (Vertical clearance)
the maximum clearance under the land side and the horizontal surface
when the plough is resting on a horizontal surface in the working position
Horizontal suction (Horizontal clearance)
maximum clearance between the land side and a horizontal plane
touching point of share at its gunnel side and heal of land side

12. Throat clearance
It is the perpendicular distance between point of share and lower position of
the beam of the plough

13. Plough size
The perpendicular distance from wing of the share
to the line jointing the point of the share and heel of land
side is called size of plough. The size of the mouldboard
plough is expressed by width of cut of the soil.
