Overview

The LH822D is a compact, powerful and stable leveling harvester. It is well suited to high performance in plantation thinning, selective felling in natural stands and final felling applications. Tight tuck boom geometry minimizes residual stand damage in thinning applications.

Purpose built for severe forest duty, the LH822D harvester offers performance and durability advantages over excavator conversions. 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 thick, one-piece turntable.  All weldments are fabricated from high quality steel to resist impact.

The FH400 leveling undercarriage has long track frames, a wide stance carbody and super duty leveling components. It all leads to rock-solid stability, poise and operator comfort on steep slopes.

The combination of high horsepower and efficient harvester head optimized hydraulics provide the operator with responsive control, quick feed speed and powerful delimbing capability for high performance and productivity.
