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.

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

4.3
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 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.

TOP
Power requirement (hp/kW) : 25-60/18.75- 45,
tractor |
Uses:
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.

|
Uses:
It is suitable for secondary tillage operation for breaking clods and
preparing seed bed for sowing purpose. It has provision to change the
disc angle. Offset type disc harrows can be used for doing
interculture in horticultural crops.

4.5
ROTAVATOR
Features:
It consists of a steel frame, 3-point hitch system, a rotary shaft on
which blades are mounted, power transmission system and a gearbox. The
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

4.6
POST-HOLE DIGGER
Features:
It consists of a frame, three point hitch system and a auger. For
