  4.1
M.B.PLOUGH
Features:
It is tractor operated implement and it consists of share point, share,
mouldboard, 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

|
Uses:
This is used for primary tillage operations. It cuts trash and buries
it completely. It is also used for turning green manure crop for

4.2 REVERSIBLE TWO BOTTOM M.B PLOUGH
|
|
 |
|
Features
The two
bottom reversible plough is a unique implement, which is directly
mounted to the tractor. This is a hydraulically /mechanically
operated basic implement for preparation of land. It is very useful
for primary tillage in hard and dry trashy land. The Mould Board (M.B)
retains their mirror finish at all time contributing to well turned
furrows. The plough has special wear resistant steel bottoms with bar
points for toughest ploughing jobs. Bar point bottom ensures longer
life as it can be extended or reversed. The M.B bottom reversing
mechanism is operated by a lever provided on the distributor. When
the implement is hitched, plough bottom is free to rotate 180 degree
along the axis of the hollow shaft. |

4.3 DISC PLOUGH
Fe
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
used where M.B. Plough is not useful such as hard and dry soil.

  4.4
TYNE TYPE 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 centimetres 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.

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 pe row spacing. |

4.5 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.

ROTAVATOR
Features:
|
It consists of a steel frame, 3-point hitch system, a rotary shaft on

blades are of L-shape, made from medium carbon steel or alloy steel,
hardened and tempered to suitable hardness It uses the power from
tractor PTO. Rotavator is used as both primary and secondary tillage
operations. A good seedbed and pulverization of the soil is achieved
in a single pass of the rotavator. It is used in both dry land and wet
land conditions. It is also suitable for incorporating straw and
manure in the field. The power requirement will vary depending upon
