Abstract

ABSTRACT Results of time studies carried out at Daphar Forest Plantation on the performance of peg-tooth crosscut saw, raker-tooth crosscut saw and power chainsaw in felling and conversion of poplar trees, show that power chain saw is very fast in cutting and demands only about 13% and 27% of the time/tree than with peg-tooth and raker-tooth crosscut saws, respectively. Power chainsaw also gives 4 and 7.2 times higher productivity of timber/hour at a cost which is about half and one fourth of the cost of work with raker-tooth and peg-tooth crosscut saws, respectively.
