Garden tools are widely used in our lives. Garden tool manufacturers say that garden tools use skills when pruning branches.
For garden tools, for long-fiber cork, cutting the sapwood can prevent it from breaking when it falls. Cut both sides of the trunk at the same height as the bottom of the groove, and the depth is about 1/10 of the diameter of the trunk. If the trunk is thick, the cutting depth must not be wider than the guide. If the wood is rotten, do not cut the sapwood cut. Saw the felling kerf slightly above the bottom of the fallen tree groove, and cut horizontally. A non-sawn area of ??about 1/10 of the diameter of the trunk is left between the felling cut and the felling groove to act as a ridge break. Drive the wedges into the felling incision in time. Only use wooden, aluminum or plastic wedges. Do not use steel wedges, otherwise it may damage the chain saw chain and cause rebound. The broken ridge helps to control the tree's falling direction. Never saw through the broken ridge, otherwise the falling direction cannot be controlled, which may cause accidents.
If the diameter of the trunk is more than twice the length of the guide plate, or the diameter of the trunk is extremely large, and most of the tree core is not cut. In order to prevent the tree core from breaking and want to accurately control the tree's falling direction, it is necessary to saw the tree core. Use a chain saw to puncture the center of the fallen tree groove, and then swing the guide plate from top to bottom in an arc.
Garden tools can be cut into simple fan-shaped cuts for thinner tree trunks. Clamp the wood inserting teeth behind the broken ridge, and make the garden tools swing on this axis. You need to pay attention to only swinging to the broken ridge so that the inserting teeth rotate around the trunk.
