摘要

A manually operated engine powered rotor-weeder for delta region with a 1.4 hp petrol engine was designed and fabricated. The field performance was evaluated and compared with the performance of a traditional manual hand hoe. The weeder consists of main frame, handle rotary blades, shaft, sprocket and chain, chassis, cutting depth hint rear cutting depth adjuster, wooden engine sitting, engine and ground wheel. The theoretical field capacity of the rotor-weeder was 0.47 ha/hr with an effective field capacity of 0.34 ha/hr, which was approximately twenty times that of manual weeding. The performance index was 1,700 and fuel consumption was 3.2 litres in 8 hours time. The rotor-weeder had a weeding efficiency of 71 % for removing shallow-rooted weeds. This suggested that the engine powered weeder could be useful equipment in modernizing agriculture for small farm holders.
