The 6900 is the first production grinder designed and built by Tigercat. The 6900 is a heavy-duty upswing grinder made for high throughput material reduction and mulch production.
With Tigercat’s legendary build quality, the 6900 is designed for extreme duty and long life, utilizing only the highest quality components. The upswing rotor and large infeed opening with outward wing walls maximize processing capacity.
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.
The machine has remote control functions for simple operation and mobility on site, along with an easy-to-use 25 cm display screen for machine monitoring and function adjustment.
Maintenance is made easy with convenient service access. The split hog box opens over centre to fully access the rotor and screens. The anvil and screens are hydraulically retractable. The single discharge conveyor is open on the bottom for clean operation and easy servicing. A tool storage area is mounted on the side of the machine that hydraulically raises and lowers for added convenience.
An optional large diameter magnetic head pulley is available to effectively remove metal from the end product. The machine is also prepared to accept over-band magnet systems.
