A Thai-made 108 kW rice combine harvester was midi"ed by replacing the cutter bar system with a stripper
header. The power requirement of the modi"ed machine was measured at no load and during "eld operation.
The stripper header system consisted of a 3 m wide stripping rotor, a metal hood and an adjustable nose. The
outer diameter of the stripping rotor was 450 mm. The stripping rotor consisted of eight rubber blades "xed on
an octagonal drum with each blade having 71 teeth. The work rate and harvesting losses were measured to
examine the "eld performance of the modi"ed machine.
