Abstract or Summary
  • To improve the present state of Forestry and the condition of forest workers is an important goal to be achieved in developing countries. With the growth of population, demand for wood products is increasing tremendously. Prices have gone up manyfold. One way to meet this demand is to increase productivity by reducing the wastage of wood and by saving time on various operations. The present tools and equipment are no longer adequate to achieve this goal so we should introduce new machines in timber harvesting. Chain saws, the first step toward mechanization, was introduced successfully, about 40 years ago in Europe and Northern iuerica. This study indicates that chain saws can be used effectively in the hilly forests of Pakistan. Productivity is increased 92 % and 29 % compared to manual tools, based on its effective time and total time respectively. The cost of the output of one cubic meter of wood with a chain saw is decreased 35 % considering its effective time but for its total time, cost is Abstract approved: 0 increased 6 % over the manual tools. This increase in cost may be reduced considerably by reducing the high delay times through better planning and crew vocational training.
