Overview & Specifications
As our largest 400 Series harvester head, the H427 delivers performance, durability and precision for big timber. With heavy-duty features and a large capacity, this powerhouse head is made for late thinnings to the final cut.
Featuring a strong frame, with an optional top saw, and HD tilt frame, the H427 delivers reliable performance and productivity. Its high feed force and cut capacity make it ideal for harvesting large-diameter timber.
The latest measuring system design improves length and diameter accuracy for efficient, high-output processing. Its efficient, powerful control valve and optimized four-roller feed arm geometry ensure consistent productivity on wheeled and tracked carriers.
The four-knife delimbing system delivers consistent, clean results, while simplified service access and a streamlined design help reduce downtime in the field. The durable H427 offers reliability in demanding forestry applications.
