Design, construction and evaluated rotary cultivator

In this study in order to reducing using of pesticides and herbicides and effective removing of row crops weeds was designed and constructed one row from four rows of mounted tractor rotary cultivator in agricultural engineering research institute in Karaj. The power supply source of system was tractor Pto shaft. The main parts comprise transmission unit, tillage unit, adaptation with rows unit was designed then was evaluated performance of machine by RNAM test procedurein Karaj Kamal Abad sugar beet research station. After working of machine in five meters distance and three replications, results proved weeding efficiency is varied between 87%-93% and theoretical field capacity for four rows is 0.6-0.64 hectare per hour and operating costs for rotary cultivator is 95% less than conventional-hand working-method.
