Experimental Field Performance Analysis of Small Weed Remover in Sugarcane Grassland

摘要

Agriculture is a backbone of country’s economy. To increase the crop production efficiency weeds are to be removed. The present weeding machines are different in dimension which may not be suited to small and medium field farmers, due cost effectiveness and dimensions. This work presents the development of sugarcane weed remover (SWR) and its performance investigation to improve the weed removal rate. The SWR is an application specific machine, it consists of single cylinder air cooled gasoline engine, blade assembly and transmission system. In order to improve SWR efficiency different blade profiles are theoretically analysed. The optimised blade profile is employed in the weed remover which offers fuel consumption of 0.11 g/(KW.h). The SWR on-field experience confirmed that the field capacity and efficiency in weeding is 0.0025 ha/hr and 60% respectively.
