The main components of the rotary tillage attachment are mainframe, power transmission system, blade assembly, hitching mechanism and protective cover. The depth of tillage obtained is 10 to 15 cm and the effective width of field coverage is 30 to 32 cm. The actual field capacity of the machine is 0.054 ha per hr and the quantity of fuel required to operate the machine is 0.860 1 per hr. Operator can easily walk behind the rotary tiller and turn the garden tractor to either side. The cost of production of the rotary tillage attachment is Rs. 1500.00 and the total cost of ploughing per hectare using the machine is Rs. 450.00.ennullThesis
