Where to buy

The H425X harvester head is purpose-built for tracked harvesters. It 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. This design improves responsiveness with unprecedented tree-processing performance, especially in large timber.

This harvester head offers options for many applications, with multi-tree handling, an integrated top saw (for processing and hardwood), and feed wheel options.
