Design and Development of Mini Tractor Operated Multipurpose Equipment for Groundnut Crop

A study was developed to design and fabricate a multipurpose equipment during the year of 2021 in the Departmental Workshop of Farm Machinery and Power Engineering and evaluated at field of Dr. NTR College of Agricultural Engineering, Bapatla, Andhra Pradesh, India. The proposed design of machine is economical to fabricate, and have greater design simplicity than its counterpart, with proper seed placement at desired depth, distance between rowsis adjusted because of tynes are fitted with the nut and bolts. Developed multipurpose equipment also done spraying and weeding attachment can be used simultaneously on single run in groundnut crop so that, the time and labour can be saved and it can be used for any narrow row crops for intercultural operations. The overall dimensions of developed multipurpose equipment are 1800×600×1550 mm and the weight of machine was 150 kg. The designed and develop machine was operated at various speeds i.e 1.8, 2.5 and 3.2 km h-1. The field efficiency while doing sowing, spraying and weeding of equipment varies from 78,83 and 78% at 1.8, 2.5 and 3.2 km h-1. The different operations were operated effectively at 2.5 km h-1. The use of multipurpose equipment helps to overcome the problems of drudgery, labour shortage timeless of operation and as a result, the farm power availability in farms can be increased. Hence, there is a need for a multipurpose implement for carrying different operations in groundnut crop.
