|
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.

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. |

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.

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. |

Features
Paddy Harrow is used for puddling for rice field in wet condition. It consists of two gangs of 8-discs mounted on a box frame in tandem. This is mounted on three point linkages of tractor and a wooden planker is attached at the rear-side of the harrow for leveling the field. It requires 40-45 hp tractors. The angle of the gangs can be adjusted with the help of a lever.
