Power harrows are classified into four types: all metal harrows, metal teeth, spring tooth harrows, and disc harrows. (Spring tooth harrows were patented by David L. Garver.)
Power harrow work in the field to prepare a seed bed while maintaining the soil’s natural composition. Power harrows are part of the work that takes place after ploughing or subsoiling for the breaking of compacted ground. The machine makes sure that there is breakage of compacted ground soil, refining the manure.
The difference between power harrows and rotavators
Although both machines are working on similar parts of the function of preparing the seed bed, there is still a difference between the two machines. The working part of the rotavator is to mix the material and prepare it for use in all types of soil, dry and wet. timely preparation of soil for sowing purposes. After harvesting the rice crop, prepare the seedbed for wheat. However, power harrows are designed for soil aeration, which works on soft soil and grassless soil.
There are several benefits of power harrows. Some of them are soil preparation, strong levelling effect, prevention of hardpan and minimum maintenance.
