To solve the problems of congestion and increased power consumption wheat combine harvesters (WCHs) caused by excessive feed rate, this paper proposes a method to reduce rate decreasing length stalk designs double-cutterbar header (DCH). Using threshing test bench taking stalk, speed tangential rotor as influencing factors conveying time index, influence different parameters on performance was ...

multistage and semi-mechanized harvesting of rice in khouzestan province, iran, causes much loss. depending on available facilities and conditions, either spike-tooth or rasp-bar cylinders are employed with either direct or indirect combine harvesting methods. the present research studied the effect of these different harvesting methods on the amount of losses in two rice varieties in 2001-2002...
