Where to buy

The Waratah H425X harvesting head is purpose-built for tracked harvesters and features a rugged main saw box with heavier steel plating, extra component guarding, hose protection, and increased drive arm durability for demanding track machine applications. The H425X four roller feed arm geometry ensures rollers grip solidly in all diameters, improving responsiveness with unprecedented tree-processing performance - especially in large timber.

Additionally, the H425X offers options for many applications, with multi-tree handling, integrated top saw (for processing and hardwood), with feed wheel or knife variations for variable stem types.
