Abstract:

Weed control is one of the most difficult tasks on an agricultural farm. Mechanical weed control not only uproots the weeds between the crop rows but also keeps the soil surface loose, ensuring better soil aeration and water intake capacity. The developed weeder should have the following features: 2.0 hp, 2-stroke petrol engine. It is compact light low weight equipment, self-propelled with durable floating system. It is centrally driven with worm gear box for transmission. The working width of the developed machine could be adjusted between 140mm to 250mm. It is equipped with rotating blades with 176 rpm and is centrally driven. The cardiac cost involved in the operation of power paddy weeder was found out and the mean working heart rate value of the subject was 108 beats min-1. The energy expended during operation of a power paddy weeder was 19.50 kJ min-1. The oxygen uptake in terms of VO2 max was 46% which was above the acceptable limit of 35% of VO2 max. Mean overall discomfort rating on a 10 point visual analogue discomfort scale (0- no discomfort, 10- extreme discomfort) was 3.0 and scaled as "light discomfort".
