Journal of the institution of engineers (India): Series ASummary: For precise hill dropping of pre-germinated paddy seeds, a wetland paddy seeder was designed and developed. In order to make it an electric motor operated self-propelled seeder, it was essential to measure the torque required to propel the seeder and force required to actuate the clutch to take turn with the seeder. A torque transducer was attached to the driving motor for measuring torque and two load cells were attached to the clutch to measure the force required to disengage the clutch. The speed of driving motor and forward speed of the seeder were measured by using inductive proximity sensor. The propelling torque, power requirement and wheel slip were measured at forward speeds of 0.5, 1 and 1.5 km/h. The torque requirement increased from 9.43 to 16.85 N-m and the corresponding power requirement increased from 20.61 to 133.63 W when the forward speed was increased from 0.5 to 1.5 km/h. The wheel slip varied from 15.53 to 29.71% within the speed range. The effect of forward speed on torque, power and wheel slip was found significant (at 1% level). Time taken by the seeder to make ‘U’ turn at the head land of field was found to be on an average 9.45–9.5 s. The force requirements to disengage the right side and left side dog clutch were measured to be 46.56 N and 49.67 N, respectively. Based on the test results a 24 V 180 W DC motor with nominal torque of 20 N-m at 80 rpm speed was selected for driving the seeder in wetland. The developed self-propelled seeder was operated satisfactorily in the puddled field.
