Overview

The L857 combines the stability of a full tail swing upper with a sloped tail for enhanced leveling capability and additional chain clearance for winch assisted operation on steep mountain terrain.

Increased Boom Envelope

The ER boom system provides tighter tuck, increased envelope and more below grade capability. Through-tip routing offers better protection of the hoses leading to the felling head. Three-mode ER provides the operator with a wide range of boom control options.

Open Access

The side opening engine roof completely exposes the top and both sides of the engine, and most hydraulic components. When open, the enclosure roof serves as a spacious side service platform to work comfortably and safely.

Designed for Steep Slopes

Optimized weight distribution and low centre of mass, along with Tigercat’s patented super duty leveling undercarriage, provide excellent stability on steep slopes. The unique sloping tail design increases leveling capability to 26 degrees. Additional clearance improves cable management on winch assist applications, reducing chain rub and interference.
