An animal drawn 3*20 wheat seed drill is equipped with a fluted roller type metering mechanism. What will be the exposed length of the fluted roller for each row if the machine is to be calibrated for seed rate of 100 kg/ha. Assuming there is no slippage in the ground wheel or in the transmission during field operations.
