N2  - Currently,  Thailand  is  the  third  largest  cassava  producer  of  the  world  and  highest  in   South- East Asia . The annual cassava  export  value of Thailand has  a growth trend  of about  100% between 2009 and 2013. There are many processes of cassava production  such as land preparation, planting, weed control, fertilization, irrigation and harvesting .  However,  share  of  labor  and  cost  in  the  harvesting  process  is  highest  compared  to  other  process.  The  labor  share  of  cassava  harvesting  is  61.7%  of  total  cassava  pr oduction.  Cassava  harvesting  has  been  always  time  and  manpower  consuming  operation.  At  the  moment,   the tractor -mounted cassava digger and conveyer is developing  in which  the famers are  involved  in  cutting,  collecting,  and  stor ing   before  it  is  used   in  the  field .  During  these processes ,  it requires  50.33 hours  (0.02 ha/hr ) per person  to  finish the land area of one  hectare .  Therefore, this research highlights the importance of new machine  and develops  the prototype model  called Cassava Stem Chopper  that  works automatically  which do not  require  any   labor  meaning  reducing   the  harvesting  cost  and  solve  labour  shortage   problem.  This  prototype  single  row  cassava  stem  chopper  consists  of   main  frame,  a   transmission gear unit, a cutting unit, a feeding unit,  and a chopping unit.  The result found  that the average chop ping capacity of this machine  was  in the range of  171-   819  kg/hr  with  the  traveling  speed  of  1.44  -   2.42  km/hr.  T he  re -germination  of  chopper  was  7.5% . In addition  to these, it was found that this cassava stem  chopper  can  work  7.5 times faster than traditional method.  The break- even point area of the  chopper  with the capacity of 0.15 ha/hr  was  equal to  46.2 ha/year at 1.45 km/hr
