Provided is a work machine with improved operatability. In a cutting tool, a guard member that is made of metal is provided inside a chip discharge passage section, and a bottom wall of the chip discharge passage section on a saw blade side is covered by the guard member. In other words, a bottom surface of the chip discharge passage section is guarded by the guard member that is made of metal. Accordingly, the guard member can prevent high-temperature metal chips from coming into direct contact with the bottom wall of the chip discharge passage section. Thus, deformation of the chip discharge passage section when chips pass through the chip discharge passage section can be suppressed. Consequently, the durability of a saw cover can be increased, and the operatability of the cutting tool can be improved.

A hydraulic separation system and method enables efficient recycling of log yard waste from an elevated frame. The system separates fine granules, small rocks, small bark, large bark, and large rocks with a variety of sequentially positioned, hydraulically powered separating components. The separation is mechanical and the size and weight of the individual material determines where in the system it is separated. Conveyors carry the log yard waste through the system. Shaking screens shake in a fast, up and down motion to flip and move the material through the system. Adjustable sloped plates work to accelerate and decelerate the material through the system. Dampening fingers control the disposition of elongated pieces of large bark and help to decelerate down the material. Blowers separate the bark from heavier rock and granular material. The elevated frame to enable cleaning and access to materials discharged beneath the elevated frame.
