Abstract
Weeds are one of the major causes of loss of agricultural produce. Weeds compete with crops for essential nutrients. In agriculture, it’s a very difficult task to weed out unwanted plants manually as well as using bullock operated equipment’s which may further lead to damage of main crops. More than 33 percent of the cost incurred in cultivation is diverted to weeding operations there by reducing the profit share of farmers. Weeders are machines used for weed removal. Mechanical weeding is one of the prominent forms of weed removal. Smaller weeding machines commonly known as portable weeders are solely used for weed removal in agricultural fields, gardens, public parks, etc. Unlike tractors, weeders are non-conventional so far as the displacement of labours is concerned. In promoting weeders especially considering the fact that the majority of farmers are having small land. So they can hardly afford costlier tractors. Therefore, the weeder should become a useful machine in the internal cleaning of crops which having small distance between them like groundnuts, sugarcane, soya bin crops, cultivation of paddy, in particular, and other crops in general for the smaller farmers. Main objective of weeder is to reduce the manpower as in today labours are very hard to find as well as working time is more Rotary tillers power is directly transmitted to the tillage blades, so the power transmission efficiency in rotary tillers is high. Hence there is a need to improve the design of blade through geometrical modifications so that will reduce the blade cost as well as land preparation cost. CAD, CAE & FEM are useful tools for analysing stresses and deformations in design of complex geometries.
