TILLAGE IMPLEMENTS
4.1
M.B.PLOUGH
Features:
It is tractor operated implement and it consists of share point, share,
mould board, landside, frog, shank, frame and hitch system. The share
point is of bar type and is made from high carbon steel or low alloy
steel. The share is also made from high carbon steel or low alloy steel.
Both are hardened and tempered to suitable hardness (about 45 ARC). The
working of the plough is controlled by hydraulic system of the tractor.
Mould board plough is a primary tillage implement.

It is used for primary tillage operations. It cuts trash and buries it
completely. It is also used for turning green manure crop for decaying
under the soil, which adds humus to the soil. It is also used
for turning and mixing compost, farmyard manure or lime into the soil. |

DISC PLOUGH
Features:
The plough consists of common main frame, disc beam assemblies, rockshaft
category-1 or category-2, a heave spring loaded furrow wheel and a gauge
wheel. In some model disc plough is designed to operate as 2, 3 or 4
bottoms, by adding or removing sub beams the sub beam assemblies according
to requirement. The disc angle ranges from 40-450 to obtain the
desired width of cut and the tilt angle ranges from 15-25 0 for
penetration. Disc plough is used for primary tillage and it is specially

TRACTOR MOUNTED CULTIVATOR
Features:
Cultivator consists of a frame, tynes (fixed or spring loaded) having
reversible shovels and 3-pont hitch system. Cultivators are primarily used
for intercultural operation after the crop has come up a few centimeters
above the ground. But cultivator is also used for opening the land,
preparing the seed bed and sowing of the seeds as well cultivators for the
secondary tillage are available as animal drawn and tractor drawn. In
medium and light soil duck foot type cultivators are also used for primary
tillage operation.

Duck foot type cultivator is used for tillage operation, destruction
of weeds and retention of soil moisture. Shovel type cultivator is
used for seed bed preparation, also used for intercultural operation
by adjusting the tynes as per row spacing. |
Cost (Rs) : 15,000-25,000

4.4
DISC HARROW
Features:
The tractor mounted disc harrow consists of two gangs of discs mounted one
behind the other. The disc on front gang throws soil outwards and the rear
gang inward. Therefore, no soil remains uncut by the offset disc harrow.
Disc harrow is secondary tillage implement. It is used after the primary
tillage. It is used to break the clods developed during primary tillage
operation.
