Abstract

Tree felling is the most important component among tree harvesting consisting of cutting, limbing, BUCKING and topping. BUCKING is the operation resulting in a felled tree being cut into logs. Motor-manual tree BUCKING in hardwood forest is the effective and important components that will result in the greatest value being recovered from the tree for a specific end use. This research was carried out in two compartments of Namkhaneh district, in KHEYRUD FOREST to assess the efficiency of BUCKING operations. This research was aimed to TIME STUDY of tree BUCKING operation in SHORT AND LONG LOG METHODs, estimate the productivity and COSTs of chainsaw, and develop a REGRESSION MODEL. Factors affecting the BUCKING time REGRESSION MODEL were DBH and tree length in short log and DBH in long log method. The hourly PRODUCTION of BUCKING in short log method with and without delay time was 35.57 m3/h and 56.86 m3/h, respectively. However, in long log method, the hourly PRODUCTIONs with and without delay time were 79.85 m3/h and 134.12 m3/h, respectively. BUCKING productivity in those methods were increased related to DBH as power. The unit COST of BUCKING operation in SHORT AND LONG LOG METHOD were decreased as power when DBH increased. Total BUCKING cycle time with delay averaged 6.77 and 3.44 minutes in SHORT AND LONG LOG METHOD, respectively.
