A stump grinder is a machine designed to remove tree stumps by using a rotating cutting disc that chips away the wood. The machine typically features a cutter wheel with fixed carbide teeth. The cutter wheel's movements are controlled by hydraulic cylinders, which allow it to move laterally and vertically to grind through the stump.
The semi-chisel chain has teeth with rounded corners formed by a radius between the top and side plates. While slower than full chisel in softwood, it retains an acceptable cutting sharpness longer, making it the preferred choice for dirtier wood, hard or dry wood, frozen wood or stump work, all of which would rapidly degrade full chisel chain ...
Time-lapse of Tigercat mulcher clearing brush. Forestry mulching is a land clearing method that uses a single machine to cut, grind, and clear vegetation.. A forestry mulching machine, also referred to as a forestry mulcher, forest masticator, or brushcutter, uses a rotary drum equipped with steel chipper tools ("teeth") or blades to shred vegetation.

Teeth designed to cut with the grain (ripping) are generally steeper than teeth designed to cut across the grain (crosscutting) Teeth: Sharp protrusions along the cutting side of the saw. Toe: The end farthest from the handle. Toothed edge: the edge with the teeth (on some saws both edges are toothed).
Built into each tooth is a depth gauge or "raker", which rides ahead of the tooth and limits the depth of cut, typically to around 0.5 mm (0.025"). Depth gauges are critical to safe chain operation. If left too high, they cause very slow cutting; if filed too low, the chain becomes more prone to kick back.
Best safety requires that the chain is properly sharpened. One key sharpening parameter is the depth gauge setting. The depth gauge is the small steel protuberance in front of each cutting tooth. The difference in height between the leading cutting edge and the depth gauge determines the thickness of the wood chip taken by the cutter.
