Design and Development of Power Puddler Implemented with Two-wheel Tractor

Abstract

 A power puddler implemented with a 11 hp two - wheel tractor was developed for primany and secondary tillage in irrigated paddy field.  Diesel engine (11 hp) was used for the power puddler.  The power engine was transmitted by pulley to rotary gearbox (ratio 1.46:1) with the chain and sprocket (ratio 1.88:1).  The cutting width of power puddler was 1.20 m.  There were six disk holder flanges fitted with 36 L - C type blades on the tiller shft.  The flangs were located on attain spiral form of the blade.  The spped of tye rotor ws 204 rpm with engine spped 2,400 rpm.  On the irrigted paddy of Phatum  Thani province. The power puddler ws used for primary tillage, field capacity was 2.88 rai/hr wiht 91.59% field efficiency.  fuel consumption was 1.40 I/rau (sum of two - wheel tractor and power puddler).  After water was being kept in the field for 1 day, the power puddler was used for secondary tillage.  Field capacity was 3.11 rai/hr with field efficiency 94.63 %, fuel consumption was 1.28 KI/rai (sum of two - wheel tractor and power puddler) and puddling index was 60 %.
