5. Bucking a log
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 as illustrated in Figure 3, it is cut from the top
(overbuck), avoid contacting ground as this will greatly reduce the chain sharpness.

When the log is supported on one end, as illustrated in Figure 4, cut 1/3 the diameter from the
underside ( underbuck) (1). Then make the finished cut by overbucking (2) to meet the first cut.

When bucking on a slope always stand on the uphill side of the log, as illustrated in Figure 6. When
