| Abstract | ||||
| This trial is to use an innovative spiral rotor tiller for tillage heavy and dry clay soil texture. Efficiency of cutting and loosening soil layer indices soil pulverization, tillage profile, specific resistance (N/m2) of spiral rotor share and power requirements (kW) are identified to evaluate the performance of spiral rotor tiller. The studied variables are four setting angles with direction line of zero, 25°, 50° and 75°, three tilling angles of 25°, 30°, and 35° and four forward speeds of 1.0, 1.5, 2.0, and 2.5 km/h in heavy and dry clay soil. The results related that increasing setting angle from 0° to 75° the MWD decreased by about 48%, and also both of the specific resistance of thespiral rotor share and power requirement decreased by 45.8 and 39.8% respectively, while the tillage width increased by about 50% at forward speed 1.5 km/h and tilling angle 25°. | ||||
