A tractor operated rotary weeder was designed using computer aided design software and prototype was fabricated. The weeder was evaluated for its field performance in cotton crop. The experiments were conducted at three forward speeds (2.0, 2.5 and 3.0 km h-1), with two rotary speeds (210 and 240 rpm) for three different types of blades (L-type, C-type and J-type). The better performance of tractor operated rotary weeder was observed at 2.5 km h-1 forward speed with rotary speed of 210 rpm for L-type blade compared to other types. Results of field performance evaluation showed that the weeding efficiency and plant damage of the weeder were 89.50% and 3.75% with a fuel consumption of 5.5 lh-1 with an area coverage of 0.43 ha h-1. The cost of operation for the weeder was estimated to be Rs.1357 ha-1 as against Rs.2500 ha-1 for conventional method of manual weeding. The breakeven point for rotary weeder was found to be 98 h per annum with a payback period of 2.3 years.
