Abstract | A stripper harvester f or rice developed a t t h e International Rice Research Institute ( IRRI ) bas e d o n a mechanism developed by Silsoe Research Institute was field tested to evaluate its field performance a nd to assess its prospect of adoption by the Filipino farmers. The machine was found to perform well in dry conditions . Average field capacity of t e machine was 0 . 12 ha/h with forward speed varying from 3. 5 to 5 km/h depending on crop and soil conditions. Shattering loss decreased with increase in forward speed while straw intake decreased at high rotor a nd low nose set ting s. Total machine loss was less than 2% of yield with negligible unstripped loss. In good standing crop, the s tripper handled less than one third of the straw as compared to manual arid mechanical reaping. Th e machine was able to thresh up to 97% of the grain s in the s tripped material. The labor requirement of u sing the stripper was 34 man- h/ha as compared to about 120 ma n- h/ha for manual reaping. Th e machine is still in the prototype stage and further development efforts a nd modifications are needed to improve its overa11 performance. Furthermore, the stripper sti11 needs t o b e tested during the wet harvest season to evaluate its performance in wet crop and soil conditions. |
