Weeding is a time consuming and tedious operation in rice farming system. So years ago a lot efforts are made to design different types of weeder like manual, animal drawn, self-powered or tractor operated. The existing STIHL power weeder is self-powered, low weight, two row type, have features like 1.8 hp, 2-stroke petrol engine. Modified version has float with centrally driven worm gear system for power transmission. The minimum row to row distance should be 25 cm with line sowing/transplanting for better operation of weeder.  One extra covering attachment is given to protect the splashing of mud into the operator surface. Alternate peg system in weeding wheel is provided for weeding in row. Modified weeder took less time (2 hours) to cover one-acre area. The cost incurred to cover one-acre area for modified weeder is INR 500 in comparison to existing weeder is INR 750.

Key word: Power weeder, Cost, Modified weeder, Float, Row to row distance.
