Harrow is a piece of primary tillage equipment that used to divide the clods after ploughing, to gather the trash from the cultivated and to straighten the seedbed. The use of harrow on the field is known as harrowing work. 


Harrowing


Harrowing is a secondary tillage process which grinds, smoothens and prepares the soil, as in seedbed preparation and control weeds activity.


There are several types of harrow used in agriculture here is a list.


  • Disc Harrow
  • Tine Harrow
  • Chain Disc Harrow
  • Spike Tooth Harrow
  • Zig-zag Harrow
  • Blade Harrow
  • Other types.


Disc Harrow


Disc harrow one of the most used agriculture machine that performs harrowing works by wheeling steel discs, each set being positioned on a common shaft. These are powered by the pulling force. 


Types of Disc Harrows


If we explore the types of a disc harrow then we need to look back in the history. Plough was the common method to develop the land but at the beginning of nineteenth-century harrows comes in play. These harrows also made with the wood and steel structure and get power from the animals. With the invention of tractors, these become so popular and convenient in-field preparation work. Types of disc harrow mainly depend on their gang configuration or trailed or mounted type. 


Disc harrows are of two types depending upon the origins of power.


1. Tractor drawn Harrow

2. Animal drawn Harrow


Tractor drawn disc harrow


When it comes to breaking hard ground, full of straws and grasses then disc harrows are best in use. A tractor-drawn disc harrow cuts the lumps of clay, clods and bulbs. 


If we talk about the structure and work of a harrow then the main role can be defined by the arrangement of the discs. Discs are positioned on one, two or more shafts which may be arranged at a variable angle to the line of movement.


As the harrow is pulled by a tractor, the discs revolve on the ground.

Depending upon the disc organisations, disc harrows are classified into two classes: 


1. Single action disc harrow

2. Double action disc harrow


Single action disc harrow


  • This type of disc harrow got two-disc gangs set end to end, which throws the soil in different directions.
  • The discs are organised in such a way that the right side gang launches the soil towards the right, and left side gang dispenses the soil towards left 


Double action harrow


  • With double action disc harrow, one or two gangs follow behind the set of the other one or two, designed in such a way that the front and back groups project the soil in opposing directions. With this harrow entire field is worked double in every trip.


It may be of two types of as follows- 


1. Tandem Disc Harrow

2. Off-set Disc Harrow


Tandem disc harrow


In the tandem disc harrow, four gangs of the disc are arranged at angled in opposite direction with the pulling power can be divided equally.


Off-set disc harrow


In the off-set arrangement two gangs added in front and behind as in tandem, able of being off-set to both side of the centre line of pull. With disc facing the opposite direction, the soil is thrown in both directions. Disc gangs are organised at suitable angles so that both drives are counter checked with each other.


Off-set disc harrow used in orchards and gardens and it line of pulling is not middle, moves left to right of the tractor that's why named as off-set disc harrow.
