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. |

: 1778 : 889 : 1092 : 253 : 45/33.75 |
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. Cost of Machine : Rs.30,000/- |

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 mould board 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. |

Uses:
It is used for
primary tillage operation and does not leave any dead furrow or uneven and sunken
spots in the field. The bottoms are so arranged that the right turning bottoms
can be quickly replaced with a set that turns the soil to the left.

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

4.5 TRAILED OR MOUNTED TYPE DISC ARROW |
||
|
|
|
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/- |

Features: The duckfoot
cultivator consists of a box type steel rectangular frame, rigid tynes and sweeps. The sweeps are triangular in shape
similar to foot of duck, hence called duckfoot
cultivator. The sweeps are made from old leaf spring steel and fixed to tynes with fasteners, which makes them replaceable after
being worn out or becoming dull. The tynes are made
of mild steel flat and forged to shape.
It is a tractor-mounted implement and depth of operation is controlled
by hydraulic system. The sweep cultivator is popular in black cotton soils.
This cultivator is mostly used in hard soils for shallow ploughing. Specification |

|
|
|
|
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. |

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. |
