We made our all-time leader, the 622B, better than ever with the HTH622B Series-III. This harvesting and processing head delivers increased productivity, improved feeding and saw performance.
The valve offers better flow-through characteristics for reducing heat, while improving feed speed and sawing performance. A measuring arm with 30 mm more travel and sensor protection provide increased accuracy in measuring crooked wood and improved uptime.
The twin retainer front knife and strengthened upper delimb castings contribute to improved delimbing durability. This harvester head also features a tilt frame and optional integrated color marking system.
A stronger valve cover and hinges as well as reinforced drive arm covers keep key components protected. Additionally, new handles and a tool-less entry provide access to a simplified hose layout. A larger saw oil filler makes for faster fills with less spills.
