| Abstract | Experiments were conducted in Bangkok clay soil to investigate the effect of tine types on pudding performance. For this purpose ·c· - shaped and 'L' - shaped blades were used. A third type of tine configuration was formed by mounting ·c· and 'L' blades toget11er called as 'C-L' type. Tests were conducted at different forward speeds of 1.0, 1. 5 and 2.0 kmph. The PTO torque was measured by slip ring torque transducer mounted wiU1 PTO drive shaft. The performance was evaluated at the end of 1st, 2nd and 3rd pass. The PTO power consumed was calculated from the PTO torque and speed data. The puddling performance of different blades was evaluated in terms of PTO power consumed, change in soil bulk density, dropping cone penetration, cone index, hydraulic conductivity, puddling index, viscosity, shear strength and clod aggregate size. It was found tho.t the power consumption by 'C' was lower than 'L' and 'C-L' blade attachment at any forward speed and pass combination. 'L' blade required 34% higher power than 'C' at pass 1 nnd 1.0 kmph forward speed. The power consumed was n function of number of pass. For all blades power during U1e 1st pass was higher than other two passes. 'C' blade performed better puddling than 'L' and 'C-L' blade attachment in terms of bulk density, falling cone penetration, cone index, puddling index, viscosity, shear strength, clod and aggregate distribution. The percent reduction in hydraulic conductivity by 'L' and 'C-L' blades was more than 'C' type blade attachment. The minimum hydraulic conductivity was found to be 0.81 mm/hr. |
