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.

LH822D with 575 bushfire salvage, Australia
This LH822D is equipped with the 575 harvesting head. This machine was destined to showcase at AUSTimber 2020 but unfortunately never made it due to COVID-19. This unit has the shorter 8,2 metre (27 ft) boom option for better stability & lift capacity in larger trees and is working in the Green Hills region of southern NSW State Forests where approximately 52 000 hectares (128,495 acres) of plantation Radiata pine was burned by bushfires earlier this year. A huge thank you to P & T Lonergan, G & J Groves Pty Ltd, and Oldina Logging for running the machine demo for us, and also to FCNSW for allowing the demo during these challenging times. Onetrak’s Tumut branch has worked hard to get this demo organized. Thank you Onetrak. Download in HD
