Abstract: The performance of precision planters is very important for attaining uniform seed spacing. Seed metering units of planters receive their motion from the driving wheel through various transmission members such as the chains, gears, shafts and belts. The slippery situation that do occur at the driving wheel adversely affects the performance of the metering unit. The research aimed at developing a planter whose metering wheel is totally eliminated and the entire operation could be well monitored. The DC motor incorporated to drive the metering shaft was powered by the pulses generated through the ON and OFF situations of the transistor. The planter was evaluated to determine its optimum operational conditions. The results showed that the forward speed of the planter is proportional to the rotational speed of the metering shaft. The optimum speed of the metering shaft is 45 rpm at the forward speed of 1.3 m/s.
