Where to buy

The H425 harvester head combines large time-cutting power with excellent delimbing quality.

This harvester head gives unprecedented tree-processing performance, especially in large timber. The feed-roller-arm geometry ensures rollers grip solidly and reliably carry trunks in all diameter ranges.

The H425 offers a solution for final felling with its two saw box options for variable stem types: standard (narrow stem) and buttress (wide stem). This head is hard to beat when it comes to productivity, uptime and low daily operating costs for loggers.
