New Implements for mechanical weeding: hoe, rotating ring blade, oscillating edge, rotating multi-edged ring and orchard rotavator have been designed and tested. The best weed control effect of a single treatment was obtained with the rotavator (96.5 percent). Rotary multi-edged ring was not quite as efficient (85.0 percent) while the efficacy of the hoe was only 59.4 percent. Tools on vertical axis shallowly penetrating soil seem to be most promising due to working with a low rotating velocity. Three treatments with the rotavator and seven with the hoe were required in order to keep the acceptable level of weeds during the period of April-August
