4.1 M.B PLOUGH
|
|
Features
It is a tractor-operated implement and consists of share point, share,
mould board, landslide, frog, shank, frame and three point 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 lever and three-point linkage. Its bar point makes it
suitable to break hardpan of the soil.

Uses:
It is used for primary tillage operations. It cuts trash and buries it
completely into the soil. 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 mainframe, disc beam assemblies,
rockshaft category –l or category -2, a heavy spring loaded furrow
wheel and a gauge wheel. In some models disc plough is designed to
operate as 2, 3 or 4 bottom, by adding or removing the sub-beam
assemblies according to requirement. The disc angle ranges from 40 to
450 to obtain the desired width of cut and the tilt angle
ranges from 15 to 250 for penetration. The discs of the
plough are made of high carbon steel or alloy steel and the edges are
hardened and sharpened. The discs are mounted on tapered roller
bearings. Scrapers prevent soil build up on the discs in sticky soils.
The furrow slice rides along the curvature and is pulverized to some
extent before being thrown.

4.3 TYNE TYPE
CULTIVATOR
|
|
|
Features
Cultivator consists of a frame, tynes fixed with reversible
shovels, 3-pont hitch system and heavy-duty springs. These
cultivators may or may not be fitted with springs. The function of
springs is to save the cultivator tynes from breaking when some
hard object comes in contact with the shovel or under the tyne.
The shovels are made of heat-treated steel for longer life. The
implement is mounted type and is controlled by the hydraulic
system of the tractor.

Uses:
Cultivators are used for seedbed preparation both in dry and wet
soils. It is also used for intercultural purpose by adjusting the
tynes in wider row crops. It is also used for puddling
purposes.
Cost of Machine : Rs.25,000 - Rs 30,000/-

4.4 DISC
HARROW
|
|
|
Features
The tractor mounted disc harrow consists of two gangs of discs
mounted one behind the other. The discs on the front gang throw
soil outward and the rear gang inward. Therefore, no soil remains
uncut by the offset disc harrow. The harrow consists of a sturdy
frame, discs arranged in two gangs, and three-point linkage. Discs
are important component of the harrow and are made from high
carbon steel or alloy steel; the cutting edges are hardened and
tempered to suitable hardness. The gangs can be moved in either
direction on the hitch frame. The rear gang can be moved the same
amount as the front gang. When operating in orchards or
plantations, the harrow can be offset to the right or left, thus
enabling soil to be thrown towards or away from the trees and
makes it possible to work under low–hanging branches. Discs with
notches on the outer rim are also available for operation in
weed-infested fields. Three point hydraulic linkage and hydraulic
control makes it highly maneuverable.

Uses:
The disc harrow is used for primary and secondary tillage
operations. It is ideal for field disking, especially in orchards,
plantations and vineyard. It is suitable for working under trees
close to the bunds and fence posts.
Cost of Machines : Rs.35,000/-
4.5 POWER
TILLER OPERATED ROTARY TILLER
|
|
Features
The power tiller is powered with an 8-15 hp diesel engine. The
engine power is transmitted to ground wheels through V –belt
pulley. A tail wheel is provided at the rear to maintain the
operating depth. The rotary weeding attachment does weeding.
The rotary weeder consists of three rows of discs mounted with
6 numbers of curved blades in opposite directions
alternatively on each disc. These blades help in cutting and
mulching the soil. The width of coverage of the rotary tiller
is 500 mm and the depth of operation can be adjusted to weed
and mulch the soil in the cropped field.

Uses:
It is for mechanical control of weeds in crops such as
tapioca, cotton, sugarcane, maize, tomato and pulses whose
rows spacing is more than 450 rpm. Attachments like sweep
blades, ridger, trailer can be used with the machine. The
lightweight power tiller can also be used for tillage under
hill agriculture and terrace farming.
Cost of Machine : Rs.1,25,000/-
4.6
ROTAVATOR
|
|
Features
It consists of a steel frame with three point hitch
system, a rotary shaft on which blades are mounted, power
transmission system, and gearbox. The blades are of
L-shape, made from medium carbon steel or alloy steel,
hardened and tempered to suitable hardness. The PTO of
tractor drives the rotavator blades. Rotary motion of the
PTO is transmitted to the shaft carrying the blades
through gearbox and transmission system. A good seedbed
and pulverization of the soil is achieved in a single pass
of the rotavator. The power requirement will vary
depending upon the width of the rotavator. The horse power
of the tractor used will depend on the size of the
rotavator.

PULVERISING ROLLER
|
|
Features
Pulverizing roller is an attachment to a commercially
available cultivator. The pulverizing roller consists
of star wheels, central shaft, pulverizing members,
mounting link and depth controlling wheel. The
pulverizing members are similar in shape to lawn mower
blades and are inserted in the cast star wheels in
such a way that it forms helical shape and
progressively come in contact with soil and breaks it.
The roller is attached to the cultivator with the help
of two mounting links having bearing housing on one
side and tensile springs on other side.
