    AbstractThe objective of this research was to study the influence of threshing unit design of axial flow rice combine harvesters

    on harvesting losses when harvest Chainat 1 rice variety, which yields relatively higher losses from a threshing unit. The sampleconsisted of 17 machines in irrigated area of Khon Kaen, Kalasin and Mahasarakam provinces. The result of the researchindicated that the concave rod clearance (RC) was the most influenced on the loss equal 27.54%. The second, third and forthinfluence on the loss were the clearance between the lower concave and the tip of the teeth in horizontal (SC), concave clearance(CC) and the clearance between the upper concave and tip of the tooth in vertical (UC) which were 25.86%, 20.29% and 15.27%respectively. The number of tooth (NT), the rotor diameter (RD), and the height of tooth (HT) were little influenced on the lossequal 9.14%, 1.90%, and 0.22% respectively.Keywords: Threshing unit, Axial flow rice combine harvester, Harvesting, Losses

    Effects of Operating of Difference Type of Cutter Bar Driver on Vibration and Header Lossesof a Thai Combine Harvester

    1) 2)Somchai Chuan-Udom1) Waree Srison2)

    AbstractThe objective of this study was to determine effects of operating of difference type of cutter bar driver on vibration and

    header losses of a Thai combine harvester. Four types of cutter bar drivers were tested: reciprocating type, stir type, perpendicularaxis type driven by chain, and perpendicular axis type driven by belt. Comparative vibration and header loss of the 4 types weretested. Results of the test indicated that the 4 type tested similarly in the header loss. The vibration of the header tended to be lowestwhen using the perpendicular axis type driv
