Bucking a Log (see figures K – N)

Bucking is cutting a log into lengths. It is important to make 
sure your footing is firm and your weight is evenly distributed 
on both feet. When possible, the log should be raised and 
supported by the use of limbs, logs or chocks. Follow the 
simple directions for easy cutting.

When the log is supported along its entire length, it is cut from 
the top (overbuck).

When the log is supported on one end, cut 1/3 the diameter 
from the underside (underbuck). Then make the finished cut 
by overbucking to meet the first cut.

When the log is supported on both ends, cut 1/3 the diameter 
from the top overbuck. Then make the finished cut by 
underbucking the lower 2/3 to meet the first cut.

When bucking on a slope, always stand on the uphill side of 
the log. When “cutting through”, release the cutting pressure 
near the end of the cut without relaxing your grip on the chain 
saw handles in order to maintain complete control. Don’t let 
the chain contact the ground. After completing the cut, wait 
for the saw chain to stop before you move the chain saw. 
Always stop the chain saw motor before moving from tree to 
tree.
