Development and Performance Evaluation of a Prototype Electrically Powered Brush Cutter

Abstract

An electrically operated brush cutter was developed and fabricated to eliminate inherent ergonomic designs and costs of imported brush cutters and also improve performance efficiency. The machine incorporated an electric power pack which provides 4hours of continuous power for cutting, ergonomic design a ground wheel roller was introduced to reduce carpal disorder that could be associated with hand held brush cutters. Machine effective efficiency is rated at 46.67% and the blade cutting efficiency is 87.5%. The minimum height of cut is 1.3mm while the machine is capable of operating at variable conditions. The estimated cost of the machine is N10, 000.00 compare to the cost of imported machines
