25 Questions

1. 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.

25. A 4*100 cm seed drill is to be operated at a forward speed of 3.6 km/h. The diameter of the ground wheel is 50 cm. a cup type metering mechanism with 10 cells on its periphery is used for dropping one seed in a hill. Power transmitted from the ground wheel shaft to the metering shaft with the help of chain and sprocket arrangement. If the desired plant population is 6000 per hectare and average emergence is 75% speed ratio between ground wheel shaft and metering shaft will be ____________
