Problem Statement:

sowing seeds in rocky land

---

Detail:

A normal harrow proves inadequate in the rocky or hard surface. Round steel rings or a roll of strings can be attached to the harrow to make it mobile and mechanical. By this method sowing can be done successfully in rocky lands also. This implement has huge potential if perfected. Farmers in most parts of the country do not or cannot bring under the plough such land as that which has a lot of embedded rocks or stones. The mobile harrow has potential to put fallow lands to continuous cultivation.
