Abstract Agriculture performs a critical role in Indian economy. The cause behind reduction in the productiveness of agricultural is weeds. Weed removal is serious problem faced by the farmers that will decrease the farmer pastime to proceed cultivation. The main objective of this paper is to assemble and advance a battery operated weeder to furnish the excellent possibilities for cultivation. The working of this task is relies upon on the battery panel. This is motorizedtools pushed through the battery energy which moves blades to cut the weeds by way of chain sprocket mechanism. The plan is simple and convenient to operate. This tools is designed to limit the human effort, to limit the price and provide the efficient work output. This weeder will fulfill the necessities of the marginal farmers.

Weed control is one of the most tough tasks in agriculture that debts for a substantial share of the value involved in agriculture production. Farmers usually expressedtheirsubjectforthehighqualityweedmanipulate measurestoarresttheboomandpropagationofweeds.In Indian agriculture, it’s a very hard venture to weed out unwanted flowers manually as nicely as using bullock operated gear which may additionally further lead to damage of main crops. More than 33 percent of the value incurred in cultivation is diverted to weeding operations there bydecreasing the profitshare of farmers.A weed is actuallyanyplantwhichgrowswhereitisunwanted.Aweed canbeconceptofasanyplantgrowingintheincorrectplace attheincorrecttimeanddoingextradamagethanaccurate (Parish, 1990).
