- Abstract
A field production study was conducted for a manual harvesting system using a chainsaw and cable skidder in a central Appalachian hardwood forest site. A partial cut was performed on a 50-acre tract with an average slope of 25 percent. Felling time per tree was most affected by diameter at breast height and the distance between harvested trees while skidding cycle time was mainly affected by turn payload size and skidding distance. Productivity of chainsaw felling was 362 ft³ per productive machine hour (PMH) (2.23 thousand board feet [MBF]/PMH) with a unit cost of $8.0/cunit (100 cubic feet) ($13.0/MBF). Cable skidding productivity was 289 ft.³/PMH (1.78 MBF/PMH) and unit cost was $27.0/cunit ($50.0/MBF). The balanced manual harvesting system could produce 7,236 ft.³ per week (44.63 MBF/week) with unit cost of $37.0/cunit ($60.0/MBF).
