The power requirements of the small header combine were measured in rice field. The results were as follows.
1). Power requirements of cylinder and 2nd blower were affected by the flow rate of straw and grain.
2). The allowable flow rate for this combine was about 16-17kg/min.
3). The power distribution for combining rice were,
(1) Power of cylinder takes about 15-16 percent of the engine output.
(2) Powers of remaining stalk cutter and 2nd blower take respectively about 14-18 percent of the engine output.
(3) Powers of cutter and wheel take respectively about 8-10 percent and 6-8 percent of the engine output.
