Harrow

An Introduction to Harrow
Harrow is a traditional farm or agricultural implement consisting of a heavy frame with sharp teeths or upright disks; used to break up and even off plowed ground. This sharp equipment is used mainly for cleaning away stubble of plants before tillage or crushing clods after tillage on uncultivated land, or in sticky, heavy clay soil fields. It is equipped with a series of sharp metal disks set on edge or at an angle on one or more axles and have a sharp, revolving circular blades, used to break up soil for sowing.

Though harrows and ploughs are used for cultivating the surface of the soil, the latter differs on its cultivation type. Ploughs are preferred for deeper cultivation, whereas harrows are suitable for shallow cultivation.

 
Harrows are also used to uproot weeds, aerate the soil, and cover seeds. Its main purpose is to break up clods / lumps of soil and to provide a finer soil structure and finish that is suitable for seeding and planting operations.
 

Brief History
Some decades back, wooden harrows and implements were used for shallow cultivation. In India, a ladder like device having twiggy branches is still used. Harrows were initially horse-drawn. In modern practice they are almost always tractor-mounted implements, drawn after the tractor, either trailed or mounted on the three-point linkage.

Types of Harrows
In modern large-scale farming, harrows are of varied types. all harrows can be used in one pass to prepare the soil for seeding. They are normally available in he following types:

 
  • Disc/Disk Harrows: These types of agricultural implements are typically used for heavy work, such as following ploughing to break up the sod.
  • Tine Harrows: They are are used to refine seed-bed condition before planting. This tool is also used for weed removal in growing crops and to loosen the inter-row soils to allow for water to soak into the subsoil.
  • Chain Harrows: Chain harrows are often used for lighter work such as leveling the tilth or covering seed.

Advantages of using Harrows
Harrowing is often carried out on fields to follow the rough finish left by ploughing operations. It makes the soil finer for cultivation. The following are the main advantages of using harrows:

  • Its heavily weighted gangs provide excellent ability
  • Easy gang adjustment for the perfect level finish
  • Available in variety of blades to suit your specific requirement
  • Capable of rendering years of efficient services.
