Adaptation and Performance Evaluation of a Tractor Operated Wood Chipper Shredder

Abstract

Performance evaluation of a tractor PTO operated of Chinese Wood Chipper Shredder was conducted at a farmer’s field in Dera Ghazi Khan Area for processing of Eucalyptus tree top-trimmed mixed waste material with leaves. The average machine throughput capacity was found to be 503 kg.h-1 with an average machine efficiency of 89 percent. Total average fuel consumption and labour requirement (un-skilled + skilled) were found to be 3.5 litres and 3.53 man-hour, respectively. The machine was also tested with clean Eucalyptus stems without leaves and small branches. The average throughput capacity in this case was found to be 568 kg.h-1 with an average machine efficiency of 97 percent. Total average fuel consumption and labour requirement (unskilled + skilled) were found to be 2.90 litres and 3.09 man-hour, respectively
