As our largest 400 Series harvester head, the H427X is purpose-built for heavy-duty tracked machine applications and extreme harvesting.
The H427X features a standard, heavy-duty tilt frame and heavy-duty feed motor covers for added durability and protection. This helps provide operators with the toughness and responsiveness required with tracked applications, hardwood and large 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.
With its four-knife delimbing system, simplified service access and streamlined design, the tough H427X offers reliability for loggers in demanding applications.
