4.1 M.B PLOUGH

 

MOULD BOARD 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.

4.2 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

                      

LIGHT DUTY RIGID TYNE CULTIVATOR

DENMARK TYPE SPRING LOADED TILLER

 

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.

4.4  DISC HARROW

 

Mounted Medium Duty Offset 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.

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.

4.7 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.
