Spring Chisel Oil Palm (Elaeis guineensis Jacq) Bunch Harvester

Abstract

Spring chisel oil palm harvester was designed to reduce torn wounds of oil palm bunch by conventional harvesting tool during the early stage of harvesting (3.5 years old). The test was conducted in oil palm field at Kaosaming district, Trat province during October 2007 – September, 2009. The spring was facilitated to enhance the impact power from 27.58±0.45 to  
43.752±1.24 kg; the action could be repeated at the same position if necessary. This mechanism was found to decrease the torn wound. This average field capacity was 11.50±1.07 second/fresh fruit bunch or the average production was 9.47±0.45 kg/min.
