Evaluations of Head Feed Combine in Paddy Variety HKR – 47

Ahead feed combine was evaluated for optimization of combining parameters viz., cylinder speed (14.42, 15.53 and 16.64 m s -1 ), forward speed (3.5, 4.0 and 4.5 km h -1 ) and crop parameter viz., grain moisture content (18.2, 20.3, 22.4 %) in relation to threshing efficiency, cleaning efficiency and total grain losses for paddy variety HKR 47. The optimal threshing efficiency (99.62 %), cleaning efficiency (98.95 %) and total grain losses (1.45 %) was observed in moisture content of 18.2 %, cylinder speed of 16.64 m s -1 and forward speed of 4.5 km h -1 . Therefore, moisture content of 18.2 %, cylinder speed of 16.64 m s -1 and forward speed of 4.5 km h -1 was recommended for harvesting of paddy variety HKR 47.
