Manual Operations » Limbing and Bucking

Limbing and Bucking


Limbing is cutting branches off of felled or standing trees. Bucking is sawing felled trees into sections called logs. The length of the logs is dependent on the species of the tree and type of final product.

As a tree falls it will often brush other trees and leaves broken live limbs or dead limbs hanging in surrounding trees. Sometimes falling trees will shoot off the stump and roll sideways or ahead creating pressures on tree limbs. Loggers should never limb a tree immediately after felling. It is often a good idea to drop several trees and then refuel the saw prior to limbing. This will provide more time for overhead hazards to come down.

Prior to limbing, loggers should evaluate five potential hazards as follows:

Highlights of Limbing and Bucking Requirements
  • Limbing and Bucking must be done on the uphill side of each tree or log, where rolling or sliding of logs may be expected.
  • Precautions, such as moving to a stable position, must be taken to prevent the logs or the butt from striking employees while limbing and bucking trees.
Top Bind

Top Bind

Arrows indicate saw travel direction and cross-hatching indicates the heartwood that will break. Depending upon the soundness of the wood and the timber lie, it may be advantageous to use the end of the bar and bore from point (C) in making cuts number (1) and number (3) if it appears there could be a danger of the log slabbing.

NOTE: A wedge section could be removed when sawing cut (2) if the top bind is excessive, to allow the tree cut to close as cuts (4) and (5) are made.

Bottom Bind

Bottom Bind

Cuts are similar to those for top bind, except top and bottom cuts are reversed.
