Due to the demanding and often abrasive environment of forestry, machinery components are routinely exposed to severe forces that lead to rapid material loss. 

The primary function of wear parts is to ensure the machine continues to operate effectively by providing a durable, replaceable interface with tough materials like wood, soil, and rocks.

They are typically made from highly durable, specialized materials such as high-grade alloy steel, manganese steel, or tungsten carbide to withstand extreme conditions. Advanced treatments like surface hardening can further extend their life.

Regular inspection and replacement of these parts are crucial for safety, productivity, and the overall longevity of the equipment. Neglecting to replace worn parts can lead to decreased performance, increased fuel consumption, unexpected breakdowns, and costly damage to the main machine components.
