ABSTRACT

The existing twin wheel weeder was designed to minimize the high drudgery, time and high labor force required for the weeding. Modification of weeder was done to operate with adjustable height/length of rod, and to facilitates assembling and disassembling in less time to move very easily from one place to another. The modified weeder is tested on the field for weeding efficiency, field efficiency, soil mass manipulation, plant injury and compared with the existing twin wheel weeder. The moisture content of the testing field was found 19.3 % (w.b). Soil mass manipulation was found better in modified twin wheel weeder 3276 cm3 than the existing one (2700 cm3). It was 90.9% for modified weeder where as 86.67 % for the existing twin wheel weeder. It was 7.01% and 9.25% for modified twin wheel weeder and existing twin wheel weeder respectively. Field efficiency founed 88.33 % and 85.29 % respectively for modified and existing twin wheel weeder. The modified twin wheel weeder was found easy to transport from one place to another due to adjustable accessories.
