PRUNING AND LIMBING
Pruning is removing branches from a standing tree.
Limbing is removing branches from a felled tree.
LIMBING (Fig. 17)
* Start at base of the felled tree and work toward the top.
- Leave the larger limbs underneath the felled tree to
support the tree as you work.
Figure 17
PRUNING (Fig. 18)
Small branches - smaller than width of guide bar.
Large branches - larger than width of guide bar.
• Remove small limbs with one cut.
• Remove larger, supporting branches with the 1/3 - 2/3
cutting techniques described in the bucking section.
PRUNING PROCEDURE
