Thinning with the gafner tri-trac feller/buncher: A case study. Forest Service research paper

Technical Report ·
OSTI ID:6365041
The productivity of a small, three-wheeled shear feller/buncher was evaluated in a fifth-row plantation thinning. Standard time study data were collected during observation of 40 complete machine cycles that resulted in 182 cut trees. Regression analysis was used to examine the influence of stand variables on productivity. Productive cycle time per tree increased as tree size increased. Maximum productivity was achieved with larger tree sizes and full accumulation. Production averaged 252 trees (14.2 cords) per productive machine hour (PMH). These results are consistent with a recent Canadian study of a similar machine.
