The split hog box design allows for easy servicing of the rotor and grate components. The top can be raised at the control panel when the machine is in service mode and the engine is off.
The toolbox opens from the front and can be filled with tools from ground level. The technician is then able to climb up to the platform without the need to carry any tools.
Once on the platform, the technician can raise the toolbox and open the top cover.
The grinder’s upper frame pivots on the undercarriage, allowing the operator to adjust the infeed angle or discharge height for different material lengths. The adjustable angle eliminates the need for outriggers. The pivoting upper frame allows transport on a 46 cm (18 in) lowboy trailer without the need to fold the discharge conveyor.
