The H423 harvester head is designed to carry out a wide range of harvesting jobs from early to late thinnings, to light regeneration harvesting. It has outstanding multi-tree-handling qualities, a compact frame design and excellent power-to-weight ratios.
The H423 harvester features four feed rollers that form a circle around the stem. This unique continuous four-wheel-drive with hydraulic connected feed rollers and mechanical differential lock ensures strong, fast feeding. Its powerful, well-positioned saw unit masters fast and precise felling and crosscutting.
Thanks to a short frame and optimal placement of the one fixed delimbing and four moving knives, this head delivers superb delimbing performance. The H423 excels when loggers pair it with multi-tree-handling equipment.
