Purpose-built for high volume roadside processing, the Tigercat 850 offers many advantages over excavator conversions  – better service access, higher cooling capacity and processor head optimized hydraulics. Pair the 850 processor with the Tigercat 568 harvesting head for an all-Tigercat roadside processing solution.

Operator station

The 850 cabin is an operator’s dream. A hooked boom design and large windows with narrow side posts provide excellent visibility. An integrated cab riser and the rearVIEW camera system contributes to all-around visibility for the operator. Optimally positioned controls and a large touch screen display improve ergonomics and machine monitoring. Reduced noise levels help the operator enjoy the auxiliary audio input port, Bluetooth® audio and hands-free calling.

Optimized hydraulics

An efficient load sensing hydraulic system allows simultaneous machine and head functionality. The combination of high horsepower and processor head optimized hydraulics lead to responsive control, quick feed speed and powerful delimbing capability for high performance and productivity.

Forest duty construction

The durable design and construction starts with the Tigercat-built forest duty undercarriage and large diameter swing bearing. The upper assembly is built on a deep section turntable. All weldments are fabricated from high quality steel to resist impact.

Service access

Service access is unmatched with the ability to step down into the centre of the machine for clear, unobstructed access to the engine and daily service points. The roof enclosure tilts open to provide excellent access to the engine house. A large cast counterweight with door provides additional access to the engine from the rear of the machine. Large enclosure doors and a service platform provide easy access to all service points.

Tigercat power. Tigercat support.

The 850 processor is Tigercat FPT Tier 2 or Tier 4f powered. The Tier 4f engine conforms to the latest emissions standards in North America. With the Tier 2 engine option, Tigercat brings the benefits of Tigercat power and support to harvesting professionals around the world.
