The purposes of this research were to 1) design and construct electric power tiller 2) find the efficiency of using an electric power tiller. The results of the design and making of the electric tiller revealed that the tiller's frame uses 2-inch steel angles with dimensions of width × length x height equal to 20 x 100 x 60 centimeters and was welded together according to the main structure. Then, install a 1000-watt electric motor, a 48-volt parallel battery control box, and the gear, along with other equipment assembled into the tractor frame, such as cage steel wheels, chains and sprockets, ball bearings, volume dolls, accelerators, and wheel axles. The efficiency of the use of the electric power tiller at average speeds of 5 km/h, 10 km/h, and 15 km/h was determined by an experiment in a 1-rai area. The experiment's results revealed that an electric tiller with an average speed of 15 km/h is appropriate. It was most suitable for use because the average amount of electricity used in plowing is 1,857.83 Wh, the process took 89.50 minutes, and the experimental area was 1 rai. If one unit of electricity costs 4.2 baht per charge, it is equal to 7.77 baht and 8 hours of charge time. When compared to the trialed fuel-system tiller, 1 liter of diesel fuel cost 32.94 baht. Using an electric tiller would reduce fuel costs by 25.17 baht per 1 rai of plowing area.
