​Rotary Weeder

The Rotary Weeder is a tool used to remove weeds either manually or mechanically. It is helpful to farmers who uses minimal to zero amount of herbicides.  Manual weeding takes about 25 days solo work to finish one hectare. Pasali's latest mechanical weeder is light, one horsepower (HP), does three rows at a time and easy to operate, making it possible even for women to work with. Two weeders can to do a hectare of rice in just five hours.  However,  the latest model is still subject for further development.
