What is a Disc Harrow? Disc Harrow Type.

In the era of mechanization, there are various types of tillage implement like plogh, rotavator, ripper, power harrow, etc used for different applications, Disc harrow is one of them. The disc harrow is a secondary tillage implement used for soil preparation.

It helps in breaking up clods and surface crusts, enhances soil granulation and surface uniformity, and prevents weed growth and destroys already existing weeds.

What is a Disc Harrow from Tractor Agriculture

Types of Disc Harrows

These types of Disc Harrows are available in different sizes, gang arrangements according to different types of tractors. These are basically of 2 types.

Trailing Type

The Mounted Type Harrow is hitched to a three-point linkage of Tractor and is raised using hydraulic power when transportation is completed.

Disc Harrows are available in many forms like:

i) Single Action

ii) Double Action

iii) Offset Type

Single Action disk harrow

Single Action Disc Harrows cuts the soil in just one direction. The cutting width is usually between 4’ to 20’.

Double Action disk harrow

Double Action Disc Harrows also are named Tandem Disc Harrows. Here, Disks are arranged in such how that disc of front gang throws the soil in one direction and discs of rear gang throws the soil in another way. this sort of harrow facilitates the homogeneous mixing of soil. they're the most suitable option for such requirements.

Offset disk harrow

This type of harrows is often worked upon in an offset position i.e. why it's called offset harrow. one change in hitch makes the harrow to maneuver either to the left or right side of the tractor. this is often very fashionable nowadays because it gives a smooth soil.

Offset Discs are available in both mounted and trailing types. Their sizes vary consistent with the dimensions and capability of a tractor.

7 Best Tillage Equipment to Have for a Mechanized Farm

Tillage is the initial process in agricultural practices and half of the job of growing crops is done by tilling or managing the soil. Once a farm has perfect soil conditions, it is easier for a farmer to accomplish further farming operations.

Tilling or managing soil requires many tough jobs from digging up the weeds to providing a perfect structure to the soil for planting. Farm mechanization allows a farmer to accomplish all the harsh jobs at a farm in minimum time and maximum efficiency. A fully mechanized farm should be well equipped with the necessary farm equipment required for tillage. Here we have mentioned the most used tillage equipment in agricultural practices.

Ploughs

Ploughs are the most basic tillage equipment used to break, turn and mix the soil and works efficiently even in rocky and rooted areas. Various models used worldwide as per their functions are – mould-board plough, reversible mould-board plough, disc plough etc.

Rotary Tillers

Popularly known as Rotavator, a rotary tiller is used in both primary and secondary tillage operations. Managing soil with rotavator ensures that the land is perfectly levelled with no clods to make it perfect for planting seeds.

Harrows

Harrow is used as primary tillage equipment in an open field for superficial ploughing, smashing the clods, aerate the soil and burying the organic remains and substances under the surface. Few Harrow models are high speed disc harrow, power harrow, poly disc harrow etc.

Sub Soilers

Sub soiler are used in the areas where deep tillage is required especially to break up hardpan layers in the soil and loosening the subsoil for improved drainage, ideal root growth and mineral osmosis.

Cultivator

A cultivator is used to loosen and aerate the soil to a depth of nine inches. The cultivator is used as secondary tillage machinery that easily till the soil on each side of the rows in the fields, removing unwanted weeds and grass.

Power Harrow

Power Harrow turns breaks even the most compact soil and refines and evenly distribute the soil over the entire working field to create a perfect seedbed in a single go.

Ripper

A Ripper is used to cut the weed roots under the surface, leaving the organic matter on the upper layer of the soil. It is suitable to use even in dry and harsh lands as the equipment have a robust structure to keep it safe from damages by underground stones & roots.

With the increasing mechanization in agriculture, farmers are using new and innovative agricultural machinery to get increased benefits. To know more about the modern farm equipment read below articles.
