Abstract
The objective of this research was design and performance testing of the curve wheel lug of hand tractor to soil processing at dry area agricultural.The materials using were iron strip, cast iron, plat, nut and bolt.While tools of research were fabrication machine set like weld machine, lathe machine, grinding machine, vise and hummer, stopwatch as timer, meter as distance measurement, pole, and rope.Result of the research was showed curve wheel lug of 90 % to effect optimal grip, slip load of reduce, and upgrade of traction wheel.Based on testing in the area was result data that slip of curve lug wheel under 15 %.The result of performance testing of showed that trace tracks given optimal grip until wheel lug leaved soil.
