Where to buy

You talked. We listened. And then we made our all-time leader, the 622B, better than ever. The result? You get reinforced durability and increased accessibility. It’s ready for your toughest job, and it’s simplified to make maintenance a breeze. That’s the HTH622B Series-III.

Features include a new valve with better flow-through characteristics for reducing heat, while improving feed speed and sawing performance. A new measuring arm with 30 mm more travel and sensor protection provide increased accuracy in measuring crooked wood and improved uptime.

A new twin retainer front knife and strengthened upper delimb castings contribute to improved delimbing durability. The head also has a new tilt frame and optional integrated color marking system. A newly styled and 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, and a larger saw oil filler makes for faster fills with less spills.
