Design and Development of a Small Electric Power Walk-Behind Teller

Abstract

Abstract

          Designs and development of a small-scale electric-powered soil-walking tiller showed that the tiller dimensions were 1.2 meters wide, 1.5 meters long, and 1.41 meters high. The utilized power was a 2,000-watt motor, a 100-amp controller, and a 30-amp lithium-ion battery. The power transmission system through a sprocket chain set had a ratio of 7.806:1. Gear 1 operates at a reduction ratio of 16:1 with a rotor speed of 29.7 rpm, while Gear 2 is operated at a reduction ratio of 12:1 with a rotor speed of 42.2 rpm. The tiller generated a torque of 1.729 horsepower and had the capability of tilling soil, including sandy loam, which prepared small-scale agricultural land for crop cultivation. The performance testing of the small-scale electric-powered soil-walking tiller in sandy loam soil in conditions whereas the nearby area measured 200 square meters, or 10 x 20 meters (200 square meters), the findings were obtained: For Gear 1 and Gear 2, the wheel speeds were measured at 3.186 and 4.91 kilometers per hour, respectively. The operational times were 0.122 and 0.079 hours, with slip rates of 16.93 and 11.89. Electrical energy consumption rates were 245.66 and 157.98 watts. The plowing width was 0.55 meters. The theoretical field capacity (TFC) was 1.094 and 1.693 acres per hour, while the effective field capacity (EFC) was 1.017 and 1.574 acres per hour. Efficiency (EFF) values were 92.1 and 93.66. The efficiency test was conducted by 5 experts who inspected all aspects and were at the highest level, with a mean score of 4.77 and a standard deviation of 0.46.
