A felled and delimbed tree is cut into logs of standard sizes, a process called bucking. A logger who specialises in this job is a buck sawyer. Bucking may be done in a variety of ways depending on the logging operation. Trees that have been previously felled and moved to a landing with a log skidder are spread out for processing. While many of ...
A good rule of thumb for all felling scenarios is to make the depth of the face cut or undercut, which is your directional angles notch face the way you want the tree to fall, roughly equal to 1/3 the diameter of the tree. [5] Additionally, one should leave about 10% for your holding wood or hinge wood to direct the tree on its way to the ...
The unit cost of the feller buncher is primary affected by the tree size and the tree volume. [10] The unit felling cost is lower when the tree size increased. For example, tree with 5 inches at DBH has the unit cost of $70 while tree with 15 inches at DBH has the unit cost of $12. As the cost of feller buncher is high, only large tree volume ...
The undercut or notch cut is the guiding or aiming slot for the tree and is a V-shaped notch placed on the side of the tree in the direction of intended fall. [4] The back cut or felling cut is made on the opposite side of the tree of the undercut and is cut through the base of the tree severing the “hinge” holding the tree up. [4]

The horse's performance varies according to the team, the size and shape of the trees to be pulled and the terrain, and it can pull an average maximum cube (in direct drag) of 1m3, 1.5 for two horses, with maximum efficiency at 0.5m3 for a single horse and 0.7m3 for three horses. Performance rises to 2.5m3 if a triqueballe or foretrain is used.
Widowmaker in New Mexico. In forestry, a widowmaker or fool killer is a detached or broken limb or tree top. The name indicates that such objects can kill forest workers by falling on them, thus "making widows" of their spouses.
Only the best trees are left to seed the regeneration. In many cases the mineral soil is intentionally exposed by equipment allowing small-seeded species that require exposed soil to grow. [ 2 ] [ 6 ] Sometimes, the cut is followed by the use of herbicides or prescribed fire to suppress any undesired vegetation. [ 2 ]
